Types

type GL

type GL struct {
	// contains filtered or unexported fields
}

GL implements the OpenGL version 2.0 API. Values of this type must be created via the API function, and it must not be used after the associated OpenGL context becomes invalid.

func API

func API(context glbase.Contexter) *GL

API returns a value that offers methods matching the OpenGL version 2.0 API.

The returned API must not be used after the provided OpenGL context becomes invalid.

func (*GL) Accum

func (gl *GL) Accum(op glbase.Enum, value float32)

Accum executes an operation on the accumulation buffer.

Parameter op defines the accumulation buffer operation (GL.ACCUM, GL.LOAD, GL.ADD, GL.MULT, or GL.RETURN) and specifies how the value parameter is used.

The accumulation buffer is an extended-range color buffer. Images are not rendered into it. Rather, images rendered into one of the color buffers are added to the contents of the accumulation buffer after rendering. Effects such as antialiasing (of points, lines, and polygons), motion blur, and depth of field can be created by accumulating images generated with different transformation matrices.

Each pixel in the accumulation buffer consists of red, green, blue, and alpha values. The number of bits per component in the accumulation buffer depends on the implementation. You can examine this number by calling GetIntegerv four times, with arguments GL.ACCUM_RED_BITS, GL.ACCUM_GREEN_BITS, GL.ACCUM_BLUE_BITS, and GL.ACCUM_ALPHA_BITS. Regardless of the number of bits per component, the range of values stored by each component is (-1, 1). The accumulation buffer pixels are mapped one-to-one with frame buffer pixels.

All accumulation buffer operations are limited to the area of the current scissor box and applied identically to the red, green, blue, and alpha components of each pixel. If a Accum operation results in a value outside the range (-1, 1), the contents of an accumulation buffer pixel component are undefined.

The operations are as follows:

GL.ACCUM
    Obtains R, G, B, and A values from the buffer currently selected for
    reading (see ReadBuffer). Each component value is divided by 2 n -
    1 , where n is the number of bits allocated to each color component
    in the currently selected buffer. The result is a floating-point
    value in the range 0 1 , which is multiplied by value and added to
    the corresponding pixel component in the accumulation buffer,
    thereby updating the accumulation buffer.

GL.LOAD
    Similar to GL.ACCUM, except that the current value in the
    accumulation buffer is not used in the calculation of the new value.
    That is, the R, G, B, and A values from the currently selected
    buffer are divided by 2 n - 1 , multiplied by value, and then stored
    in the corresponding accumulation buffer cell, overwriting the
    current value.

GL.ADD
    Adds value to each R, G, B, and A in the accumulation buffer.

GL.MULT
    Multiplies each R, G, B, and A in the accumulation buffer by value
    and returns the scaled component to its corresponding accumulation
    buffer location.

GL.RETURN
    Transfers accumulation buffer values to the color buffer or buffers
    currently selected for writing. Each R, G, B, and A component is
    multiplied by value, then multiplied by 2 n - 1 , clamped to the
    range 0 2 n - 1 , and stored in the corresponding display buffer
    cell. The only fragment operations that are applied to this transfer
    are pixel ownership, scissor, dithering, and color writemasks.

To clear the accumulation buffer, call ClearAccum with R, G, B, and A values to set it to, then call Clear with the accumulation buffer enabled.

Error GL.INVALID_ENUM is generated if op is not an accepted value. GL.INVALID_OPERATION is generated if there is no accumulation buffer. GL.INVALID_OPERATION is generated if Accum is executed between the execution of Begin and the corresponding execution of End.

https://www.opengl.org/sdk/docs/man2/xhtml/glAreTexturesResident.xml

func (*GL) AttachShader

func (gl *GL) AttachShader(program glbase.Program, shader glbase.Shader)

AttachShader attaches a shader object to a program object.

In order to create an executable, there must be a way to specify the list of things that will be linked together. Program objects provide this mechanism. Shaders that are to be linked together in a program object must first be attached to that program object. This indicates that shader will be included in link operations that will be performed on program.

All operations that can be performed on a shader object are valid whether or not the shader object is attached to a program object. It is permissible to attach a shader object to a program object before source code has been loaded into the shader object or before the shader object has been compiled. It is permissible to attach multiple shader objects of the same type because each may contain a portion of the complete shader. It is also permissible to attach a shader object to more than one program object. If a shader object is deleted while it is attached to a program object, it will be flagged for deletion, and deletion will not occur until DetachShader is called to detach it from all program objects to which it is attached.

Error GL.INVALID_VALUE is generated if either program or shader is not a value generated by OpenGL. GL.INVALID_OPERATION is generated if program is not a program object. GL.INVALID_OPERATION is generated if shader is not a shader object. GL.INVALID_OPERATION is generated if shader is already attached to program. GL.INVALID_OPERATION is generated if AttachShader is executed between the execution of Begin and the corresponding execution of End.

AttachShader is available in GL version 2.0 or greater.

func (*GL) BindAttribLocation

func (gl *GL) BindAttribLocation(program glbase.Program, index glbase.Attrib, name string)

BindAttribLocation associates a user-defined attribute variable in the program object specified by program with a generic vertex attribute index. The name parameter specifies the name of the vertex shader attribute variable to which index is to be bound. When program is made part of the current state, values provided via the generic vertex attribute index will modify the value of the user-defined attribute variable specified by name.

If name refers to a matrix attribute variable, index refers to the first column of the matrix. Other matrix columns are then automatically bound to locations index+1 for a matrix of type mat2; index+1 and index+2 for a matrix of type mat3; and index+1, index+2, and index+3 for a matrix of type mat4.

This command makes it possible for vertex shaders to use descriptive names for attribute variables rather than generic variables that are numbered from 0 to GL.MAX_VERTEX_ATTRIBS-1. The values sent to each generic attribute index are part of current state, just like standard vertex attributes such as color, normal, and vertex position. If a different program object is made current by calling UseProgram, the generic vertex attributes are tracked in such a way that the same values will be observed by attributes in the new program object that are also bound to index.

Attribute variable name-to-generic attribute index bindings for a program object can be explicitly assigned at any time by calling BindAttribLocation. Attribute bindings do not go into effect until LinkProgram is called. After a program object has been linked successfully, the index values for generic attributes remain fixed (and their values can be queried) until the next link command occurs.

Applications are not allowed to bind any of the standard OpenGL vertex attributes using this command, as they are bound automatically when needed. Any attribute binding that occurs after the program object has been linked will not take effect until the next time the program object is linked.

If name was bound previously, that information is lost. Thus you cannot bind one user-defined attribute variable to multiple indices, but you can bind multiple user-defined attribute variables to the same index.

Applications are allowed to bind more than one user-defined attribute variable to the same generic vertex attribute index. This is called aliasing, and it is allowed only if just one of the aliased attributes is active in the executable program, or if no path through the shader consumes more than one attribute of a set of attributes aliased to the same location. The compiler and linker are allowed to assume that no aliasing is done and are free to employ optimizations that work only in the absence of aliasing. OpenGL implementations are not required to do error checking to detect aliasing. Because there is no way to bind standard attributes, it is not possible to alias generic attributes with conventional ones (except for generic attribute 0).

BindAttribLocation can be called before any vertex shader objects are bound to the specified program object. It is also permissible to bind a generic attribute index to an attribute variable name that is never used in a vertex shader.

Active attributes that are not explicitly bound will be bound by the linker when LinkProgram is called. The locations assigned can be queried by calling GetAttribLocation.

Error GL.INVALID_VALUE is generated if index is greater than or equal to GL.MAX_VERTEX_ATTRIBS. GL.INVALID_OPERATION is generated if name starts with the reserved prefix "gl_". GL.INVALID_VALUE is generated if program is not a value generated by OpenGL. GL.INVALID_OPERATION is generated if program is not a program object. GL.INVALID_OPERATION is generated if BindAttribLocation is executed between the execution of Begin and the corresponding execution of End.

BindAttribLocation is available in GL version 2.0 or greater.

func (*GL) BindBuffer

func (gl *GL) BindBuffer(target glbase.Enum, buffer glbase.Buffer)

BindBuffer creates or puts in use a named buffer object. Calling BindBuffer with target set to GL.ARRAY_BUFFER, GL.ELEMENT_ARRAY_BUFFER, GL.PIXEL_PACK_BUFFER or GL.PIXEL_UNPACK_BUFFER and buffer set to the name of the new buffer object binds the buffer object name to the target. When a buffer object is bound to a target, the previous binding for that target is automatically broken.

Buffer object names are unsigned integers. The value zero is reserved, but there is no default buffer object for each buffer object target. Instead, buffer set to zero effectively unbinds any buffer object previously bound, and restores client memory usage for that buffer object target. Buffer object names and the corresponding buffer object contents are local to the shared display-list space (see XCreateContext) of the current GL rendering context; two rendering contexts share buffer object names only if they also share display lists.

GenBuffers may be called to generate a set of new buffer object names.

The state of a buffer object immediately after it is first bound is an unmapped zero-sized memory buffer with GL.READ_WRITE access and GL.STATIC_DRAW usage.

While a non-zero buffer object name is bound, GL operations on the target to which it is bound affect the bound buffer object, and queries of the target to which it is bound return state from the bound buffer object. While buffer object name zero is bound, as in the initial state, attempts to modify or query state on the target to which it is bound generates an GL.INVALID_OPERATION error.

When vertex array pointer state is changed, for example by a call to NormalPointer, the current buffer object binding (GL.ARRAY_BUFFER_BINDING) is copied into the corresponding client state for the vertex array type being changed, for example GL.NORMAL_ARRAY_BUFFER_BINDING. While a non-zero buffer object is bound to the GL.ARRAY_BUFFER target, the vertex array pointer parameter that is traditionally interpreted as a pointer to client-side memory is instead interpreted as an offset within the buffer object measured in basic machine units.

While a non-zero buffer object is bound to the GL.ELEMENT_ARRAY_BUFFER target, the indices parameter of DrawElements, DrawRangeElements, or MultiDrawElements that is traditionally interpreted as a pointer to client-side memory is instead interpreted as an offset within the buffer object measured in basic machine units.

While a non-zero buffer object is bound to the GL.PIXEL_PACK_BUFFER target, the following commands are affected: GetCompressedTexImage, GetConvolutionFilter, GetHistogram, GetMinmax, GetPixelMap, GetPolygonStipple, GetSeparableFilter, GetTexImage, and ReadPixels. The pointer parameter that is traditionally interpreted as a pointer to client-side memory where the pixels are to be packed is instead interpreted as an offset within the buffer object measured in basic machine units.

While a non-zero buffer object is bound to the GL.PIXEL_UNPACK_BUFFER target, the following commands are affected: Bitmap, ColorSubTable, ColorTable, CompressedTexImage1D, CompressedTexImage2D, CompressedTexImage3D, CompressedTexSubImage1D, CompressedTexSubImage2D, CompressedTexSubImage3D, ConvolutionFilter1D, ConvolutionFilter2D, DrawPixels, PixelMap, PolygonStipple, SeparableFilter2D, TexImage1D, TexImage2D, TexImage3D, TexSubImage1D, TexSubImage2D, and TexSubImage3D. The pointer parameter that is traditionally interpreted as a pointer to client-side memory from which the pixels are to be unpacked is instead interpreted as an offset within the buffer object measured in basic machine units.

A buffer object binding created with BindBuffer remains active until a different buffer object name is bound to the same target, or until the bound buffer object is deleted with DeleteBuffers.

Once created, a named buffer object may be re-bound to any target as often as needed. However, the GL implementation may make choices about how to optimize the storage of a buffer object based on its initial binding target.

Error GL.INVALID_ENUM is generated if target is not one of the allowable values. GL.INVALID_OPERATION is generated if BindBuffer is executed between the execution of Begin and the corresponding execution of End.

BindBuffer is available in GL version 1.5 or greater.

func (*GL) BufferData

func (gl *GL) BufferData(target glbase.Enum, size int, data interface{}, usage glbase.Enum)

BufferData creates a new data store for the buffer object currently bound to target. Any pre-existing data store is deleted. The new data store is created with the specified size in bytes and usage. If data is not nil, it must be a slice that is used to initialize the data store. In that case the size parameter is ignored and the store size will match the slice data size.

In its initial state, the new data store is not mapped, it has a NULL mapped pointer, and its mapped access is GL.READ_WRITE.

The target constant must be one of GL.ARRAY_BUFFER, GL.COPY_READ_BUFFER, GL.COPY_WRITE_BUFFER, GL.ELEMENT_ARRAY_BUFFER, GL.PIXEL_PACK_BUFFER, GL.PIXEL_UNPACK_BUFFER, GL.TEXTURE_BUFFER, GL.TRANSFORM_FEEDBACK_BUFFER, or GL.UNIFORM_BUFFER.

The usage parameter is a hint to the GL implementation as to how a buffer object's data store will be accessed. This enables the GL implementation to make more intelligent decisions that may significantly impact buffer object performance. It does not, however, constrain the actual usage of the data store. usage can be broken down into two parts: first, the frequency of access (modification and usage), and second, the nature of that access.

A usage frequency of STREAM and nature of DRAW is specified via the constant GL.STREAM_DRAW, for example.

The usage frequency of access may be one of:

STREAM
    The data store contents will be modified once and used at most a few times.

STATIC
    The data store contents will be modified once and used many times.

DYNAMIC
    The data store contents will be modified repeatedly and used many times.

The usage nature of access may be one of:

DRAW
    The data store contents are modified by the application, and used as
    the source for GL drawing and image specification commands.

READ
    The data store contents are modified by reading data from the GL,
    and used to return that data when queried by the application.

COPY
    The data store contents are modified by reading data from the GL,
    and used as the source for GL drawing and image specification
    commands.

Clients must align data elements consistent with the requirements of the client platform, with an additional base-level requirement that an offset within a buffer to a datum comprising N bytes be a multiple of N.

Error GL.INVALID_ENUM is generated if target is not one of the accepted buffer targets. GL.INVALID_ENUM is generated if usage is not GL.STREAM_DRAW, GL.STREAM_READ, GL.STREAM_COPY, GL.STATIC_DRAW, GL.STATIC_READ, GL.STATIC_COPY, GL.DYNAMIC_DRAW, GL.DYNAMIC_READ, or GL.DYNAMIC_COPY. GL.INVALID_VALUE is generated if size is negative. GL.INVALID_OPERATION is generated if the reserved buffer object name 0 is bound to target. GL.OUT_OF_MEMORY is generated if the GL is unable to create a data store with the specified size.

func (*GL) CreateProgram

func (gl *GL) CreateProgram() glbase.Program

CreateProgram creates an empty program object and returns a non-zero value by which it can be referenced. A program object is an object to which shader objects can be attached. This provides a mechanism to specify the shader objects that will be linked to create a program. It also provides a means for checking the compatibility of the shaders that will be used to create a program (for instance, checking the compatibility between a vertex shader and a fragment shader). When no longer needed as part of a program object, shader objects can be detached.

One or more executables are created in a program object by successfully attaching shader objects to it with AttachShader, successfully compiling the shader objects with CompileShader, and successfully linking the program object with LinkProgram. These executables are made part of current state when UseProgram is called. Program objects can be deleted by calling DeleteProgram. The memory associated with the program object will be deleted when it is no longer part of current rendering state for any context.

Like display lists and texture objects, the name space for program objects may be shared across a set of contexts, as long as the server sides of the contexts share the same address space. If the name space is shared across contexts, any attached objects and the data associated with those attached objects are shared as well.

Applications are responsible for providing the synchronization across API calls when objects are accessed from different execution threads.

This function returns 0 if an error occurs creating the program object.

Error GL.INVALID_OPERATION is generated if CreateProgram is executed between the execution of Begin and the corresponding execution of End.

CreateProgram is available in GL version 2.0 or greater.

func (*GL) CreateShader

func (gl *GL) CreateShader(gltype glbase.Enum) glbase.Shader

CreateShader creates an empty shader object and returns a non-zero value by which it can be referenced. A shader object is used to maintain the source code strings that define a shader. shaderType indicates the type of shader to be created.

Two types of shaders are supported. A shader of type GL.VERTEX_SHADER is a shader that is intended to run on the programmable vertex processor and replace the fixed functionality vertex processing in OpenGL. A shader of type GL.FRAGMENT_SHADER is a shader that is intended to run on the programmable fragment processor and replace the fixed functionality fragment processing in OpenGL.

When created, a shader object's GL.SHADER_TYPE parameter is set to either GL.VERTEX_SHADER or GL.FRAGMENT_SHADER, depending on the value of shaderType.

Like display lists and texture objects, the name space for shader objects may be shared across a set of contexts, as long as the server sides of the contexts share the same address space. If the name space is shared across contexts, any attached objects and the data associated with those attached objects are shared as well.

This function returns 0 if an error occurs creating the shader object.

Error GL.INVALID_ENUM is generated if shaderType is not an accepted value. GL.INVALID_OPERATION is generated if CreateShader is executed between the execution of Begin and the corresponding execution of End.

CreateShader is available in GL version 2.0 or greater.

func (*GL) DeleteBuffers

func (gl *GL) DeleteBuffers(buffers []glbase.Buffer)

DeleteBuffers deletes the buffer objects whose names are stored in the buffers slice.

After a buffer object is deleted, it has no contents, and its name is free for reuse (for example by GenBuffers). If a buffer object that is currently bound is deleted, the binding reverts to 0 (the absence of any buffer object, which reverts to client memory usage).

DeleteBuffers silently ignores 0's and names that do not correspond to existing buffer objects.

Error GL.INVALID_VALUE is generated if n is negative. GL.INVALID_OPERATION is generated if DeleteBuffers is executed between the execution of Begin and the corresponding execution of End.

DeleteBuffers is available in GL version 1.5 or greater.

func (*GL) DeleteProgram

func (gl *GL) DeleteProgram(program glbase.Program)

DeleteProgram frees the memory and invalidates the name associated with the program object specified by program. This command effectively undoes the effects of a call to CreateProgram.

If a program object is in use as part of current rendering state, it will be flagged for deletion, but it will not be deleted until it is no longer part of current state for any rendering context. If a program object to be deleted has shader objects attached to it, those shader objects will be automatically detached but not deleted unless they have already been flagged for deletion by a previous call to DeleteShader. A value of 0 for program will be silently ignored.

To determine whether a program object has been flagged for deletion, call GetProgram with arguments program and GL.DELETE_STATUS.

Error GL.INVALID_VALUE is generated if program is not a value generated by OpenGL.

DeleteProgram is available in GL version 2.0 or greater.

func (*GL) DeleteShader

func (gl *GL) DeleteShader(shader glbase.Shader)

DeleteShader frees the memory and invalidates the name associated with the shader object specified by shader. This command effectively undoes the effects of a call to CreateShader.

If a shader object to be deleted is attached to a program object, it will be flagged for deletion, but it will not be deleted until it is no longer attached to any program object, for any rendering context (it must be detached from wherever it was attached before it will be deleted). A value of 0 for shader will be silently ignored.

To determine whether an object has been flagged for deletion, call GetShader with arguments shader and GL.DELETE_STATUS.

Error GL.INVALID_VALUE is generated if shader is not a value generated by OpenGL.

DeleteShader is available in GL version 2.0 or greater.

func (*GL) DeleteTextures

func (gl *GL) DeleteTextures(textures []glbase.Texture)

DeleteTextures deletes the textures objects whose names are stored in the textures slice. After a texture is deleted, it has no contents or dimensionality, and its name is free for reuse (for example by GenTextures). If a texture that is currently bound is deleted, the binding reverts to 0 (the default texture).

DeleteTextures silently ignores 0's and names that do not correspond to existing textures.

Error GL.INVALID_VALUE is generated if n is negative.

DeleteTextures is available in GL version 2.0 or greater.

func (*GL) DepthRange

func (gl *GL) DepthRange(nearVal, farVal float64)

DepthRange specifies the mapping of depth values from normalized device coordinates to window coordinates.

Parameter nearVal specifies the mapping of the near clipping plane to window coordinates (defaults to 0), while farVal specifies the mapping of the far clipping plane to window coordinates (defaults to 1).

After clipping and division by w, depth coordinates range from -1 to 1, corresponding to the near and far clipping planes. DepthRange specifies a linear mapping of the normalized depth coordinates in this range to window depth coordinates. Regardless of the actual depth buffer implementation, window coordinate depth values are treated as though they range from 0 through 1 (like color components). Thus, the values accepted by DepthRange are both clamped to this range before they are accepted.

The default setting of (0, 1) maps the near plane to 0 and the far plane to 1. With this mapping, the depth buffer range is fully utilized.

It is not necessary that nearVal be less than farVal. Reverse mappings such as nearVal 1, and farVal 0 are acceptable.

GL.INVALID_OPERATION is generated if DepthRange is executed between the execution of Begin and the corresponding execution of End.

func (*GL) GenBuffers

func (gl *GL) GenBuffers(n int) []glbase.Buffer

GenBuffers returns n buffer object names. There is no guarantee that the names form a contiguous set of integers; however, it is guaranteed that none of the returned names was in use immediately before the call to GenBuffers.

Buffer object names returned by a call to GenBuffers are not returned by subsequent calls, unless they are first deleted with DeleteBuffers.

No buffer objects are associated with the returned buffer object names until they are first bound by calling BindBuffer.

Error GL.INVALID_VALUE is generated if n is negative. GL.INVALID_OPERATION is generated if GenBuffers is executed between the execution of Begin and the corresponding execution of End.

GenBuffers is available in GL version 1.5 or greater.

func (*GL) GenTextures

func (gl *GL) GenTextures(n int) []glbase.Texture

GenTextures returns n texture names in textures. There is no guarantee that the names form a contiguous set of integers; however, it is guaranteed that none of the returned names was in use immediately before the call to GenTextures.

The generated textures have no dimensionality; they assume the dimensionality of the texture target to which they are first bound (see BindTexture).

Texture names returned by a call to GenTextures are not returned by subsequent calls, unless they are first deleted with DeleteTextures.

Error GL.INVALID_VALUE is generated if n is negative.

GenTextures is available in GL version 2.0 or greater.

https://www.opengl.org/sdk/docs/man2/xhtml/glGetAttachedShaders.xml

func (*GL) GetAttribLocation

func (gl *GL) GetAttribLocation(program glbase.Program, name string) glbase.Attrib

GetAttribLocation queries the previously linked program object specified by program for the attribute variable specified by name and returns the index of the generic vertex attribute that is bound to that attribute variable. If name is a matrix attribute variable, the index of the first column of the matrix is returned. If the named attribute variable is not an active attribute in the specified program object or if name starts with the reserved prefix "gl_", a value of -1 is returned.

The association between an attribute variable name and a generic attribute index can be specified at any time by calling BindAttribLocation. Attribute bindings do not go into effect until LinkProgram is called. After a program object has been linked successfully, the index values for attribute variables remain fixed until the next link command occurs. The attribute values can only be queried after a link if the link was successful. GetAttribLocation returns the binding that actually went into effect the last time LinkProgram was called for the specified program object. Attribute bindings that have been specified since the last link operation are not returned by GetAttribLocation.

Error GL_INVALID_OPERATION is generated if program is not a value generated by OpenGL. GL_INVALID_OPERATION is generated if program is not a program object. GL_INVALID_OPERATION is generated if program has not been successfully linked. GL_INVALID_OPERATION is generated if GetAttribLocation is executed between the execution of Begin and the corresponding execution of End.

    params returns the number of shader objects attached to program.

GL.ACTIVE_ATTRIBUTES
    params returns the number of active attribute variables for program.

GL.ACTIVE_ATTRIBUTE_MAX_LENGTH
    params returns the length of the longest active attribute name for
    program, including the null termination character (the size of
    the character buffer required to store the longest attribute name).
    If no active attributes exist, 0 is returned.

GL.ACTIVE_UNIFORMS
    params returns the number of active uniform variables for program.

GL.ACTIVE_UNIFORM_MAX_LENGTH
    params returns the length of the longest active uniform variable
    name for program, including the null termination character (i.e.,

    program will output.

GL.GEOMETRY_INPUT_TYPE
    params returns a symbolic constant indicating the primitive type accepted
    as input to the geometry shader contained in program.

GL.GEOMETRY_OUTPUT_TYPE
    params returns a symbolic constant indicating the primitive type that will
    be output by the geometry shader contained in program.

GL.ACTIVE_UNIFORM_BLOCKS and GL.ACTIVE_UNIFORM_BLOCK_MAX_NAME_LENGTH are available only if the GL version 3.1 or greater.

GL.GEOMETRY_VERTICES_OUT, GL.GEOMETRY_INPUT_TYPE and GL.GEOMETRY_OUTPUT_TYPE are accepted only if the GL version is 3.2 or greater.

func (*GL) GetShaderInfoLog

func (gl *GL) GetShaderInfoLog(shader glbase.Shader) []byte

GetShaderInfoLog returns the information log for the specified shader object. The information log for a shader object is modified when the shader is compiled.

The information log for a shader object is a string that may contain diagnostic messages, warning messages, and other information about the last compile operation. When a shader object is created, its information log will be a string of length 0, and the size of the current log can be obtained by calling GetShaderiv with the value GL.INFO_LOG_LENGTH.

The information log for a shader object is the OpenGL implementer's primary mechanism for conveying information about the compilation process. Therefore, the information log can be helpful to application developers during the development process, even when compilation is successful. Application developers should not expect different OpenGL implementations to produce identical information logs.

Error GL.INVALID_VALUE is generated if shader is not a value generated by OpenGL. GL.INVALID_OPERATION is generated if shader is not a shader object. GL.INVALID_VALUE is generated if maxLength is less than 0. GL.INVALID_OPERATION is generated if GetShaderInfoLog is executed between the execution of Begin and the corresponding execution of End.

  params returns the length of the concatenation of the source strings
  that make up the shader source for the shader, including the null
  termination character. (the size of the character buffer
  required to store the shader source). If no source code exists, 0 is
  returned.

Error GL.INVALID_VALUE is generated if shader is not a value generated by OpenGL. GL.INVALID_OPERATION is generated if shader does not refer to a shader object. GL.INVALID_ENUM is generated if pname is not an accepted value. GL.INVALID_OPERATION is generated if GetShader is executed between the execution of Begin and the corresponding execution of End.

func (*GL) GetUniformLocation

func (gl *GL) GetUniformLocation(program glbase.Program, name string) glbase.Uniform

GetUniformLocation returns an integer that represents the location of a specific uniform variable within a program object. name must be an active uniform variable name in program that is not a structure, an array of structures, or a subcomponent of a vector or a matrix. This function returns -1 if name does not correspond to an active uniform variable in program or if name starts with the reserved prefix "gl_".

Uniform variables that are structures or arrays of structures may be queried by calling GetUniformLocation for each field within the structure. The array element operator "[]" and the structure field operator "." may be used in name in order to select elements within an array or fields within a structure. The result of using these operators is not allowed to be another structure, an array of structures, or a subcomponent of a vector or a matrix. Except if the last part of name indicates a uniform variable array, the location of the first element of an array can be retrieved by using the name of the array, or by using the name appended by "[0]".

The actual locations assigned to uniform variables are not known until the program object is linked successfully. After linking has occurred, the command GetUniformLocation can be used to obtain the location of a uniform variable. This location value can then be passed to Uniform to set the value of the uniform variable or to GetUniform in order to query the current value of the uniform variable. After a program object has been linked successfully, the index values for uniform variables remain fixed until the next link command occurs. Uniform variable locations and values can only be queried after a link if the link was successful.

Error GL.INVALID_VALUE is generated if program is not a value generated by OpenGL. GL.INVALID_OPERATION is generated if program is not a program object. GL.INVALID_OPERATION is generated if program has not been successfully linked. GL.INVALID_OPERATION is generated if GetUniformLocation is executed between the execution of Begin and the corresponding execution of End.

GetUniformLocation is available in GL version 2.0 or greater.

func (*GL) GetUniformfv

func (gl *GL) GetUniformfv(program glbase.Program, location glbase.Uniform, params []float32)

GetUniformfv returns in params the value of the specified uniform variable. The type of the uniform variable specified by location determines the number of values returned. If the uniform variable is defined in the shader as a boolean, int, or float, a single value will be returned. If it is defined as a vec2, ivec2, or bvec2, two values will be returned. If it is defined as a vec3, ivec3, or bvec3, three values will be returned, and so on. To query values stored in uniform variables declared as arrays, call GetUniformfv for each element of the array. To query values stored in uniform variables declared as structures, call GetUniformfv for each field in the structure. The values for uniform variables declared as a matrix will be returned in column major order.

The locations assigned to uniform variables are not known until the program object is linked. After linking has occurred, the command GetUniformLocation can be used to obtain the location of a uniform variable. This location value can then be passed to GetUniformfv in order to query the current value of the uniform variable. After a program object has been linked successfully, the index values for uniform variables remain fixed until the next link command occurs. The uniform variable values can only be queried after a link if the link was successful.

Error GL.INVALID_VALUE is generated if program is not a value generated by OpenGL. GL.INVALID_OPERATION is generated if program is not a program object. GL.INVALID_OPERATION is generated if program has not been successfully linked. GL.INVALID_OPERATION is generated if location does not correspond to a valid uniform variable location for the specified program object. GL.INVALID_OPERATION is generated if GetUniformfv is executed between the execution of Begin and the corresponding execution of End.

GetUniformfv is available in GL version 2.0 or greater.

func (*GL) GetUniformiv

func (gl *GL) GetUniformiv(program glbase.Program, location glbase.Uniform, params []int32)

    params returns a single value, the name of the buffer object
    currently bound to the binding point corresponding to generic vertex
    attribute array index. If no buffer object is bound, 0 is returned.
    The initial value is 0.

GL.VERTEX_ATTRIB_ARRAY_ENABLED
    params returns a single value that is non-zero (true) if the vertex
    attribute array for index is enabled and 0 (false) if it is
    disabled. The initial value is 0.

GL.VERTEX_ATTRIB_ARRAY_SIZE
    params returns a single value, the size of the vertex attribute
    array for index. The size is the number of values for each element
    of the vertex attribute array, and it will be 1, 2, 3, or 4. The
    initial value is 4.

GL.VERTEX_ATTRIB_ARRAY_STRIDE
    params returns a single value, the array stride for (number of bytes
    between successive elements in) the vertex attribute array for
    index. A value of 0 indicates that the array elements are stored
    sequentially in memory. The initial value is 0.

GL.VERTEX_ATTRIB_ARRAY_TYPE
    params returns a single value, a symbolic constant indicating the
    array type for the vertex attribute array for index. Possible values
    are GL.BYTE, GL.UNSIGNED_BYTE, GL.SHORT, GL.UNSIGNED_SHORT, GL.INT,
    GL.UNSIGNED_INT, GL.FLOAT, and GL.DOUBLE. The initial value is
    GL.FLOAT.

GL.VERTEX_ATTRIB_ARRAY_NORMALIZED
    params returns a single value that is non-zero (true) if fixed-point
    data types for the vertex attribute array indicated by index are
    normalized when they are converted to floating point, and 0 (false)
    otherwise. The initial value is 0.

GL.CURRENT_VERTEX_ATTRIB
    params returns four values that represent the current value for the
    generic vertex attribute specified by index. Generic vertex
    attribute 0 is unique in that it has no current state, so an error
    will be generated if index is 0. The initial value for all other
    generic vertex attributes is (0,0,0,1).

All of the parameters except GL.CURRENT_VERTEX_ATTRIB represent client-side state.

Error GL.INVALID_VALUE is generated if index is greater than or equal to GL.MAX_VERTEX_ATTRIBS. GL.INVALID_ENUM is generated if pname is not an accepted value. GL.INVALID_OPERATION is generated if index is 0 and pname is GL.CURRENT_VERTEX_ATTRIB.

https://www.opengl.org/sdk/docs/man2/xhtml/glLineStipple.xml

func (*GL) LinkProgram

func (gl *GL) LinkProgram(program glbase.Program)

LinkProgram links the program object specified by program. If any shader objects of type GL.VERTEX_SHADER are attached to program, they will be used to create an executable that will run on the programmable vertex processor. If any shader objects of type GL.FRAGMENT_SHADER are attached to program, they will be used to create an executable that will run on the programmable fragment processor.

The status of the link operation will be stored as part of the program object's state. This value will be set to GL.TRUE if the program object was linked without errors and is ready for use, and GL.FALSE otherwise. It can be queried by calling GetProgramiv with arguments program and GL.LINK_STATUS.

As a result of a successful link operation, all active user-defined uniform variables belonging to program will be initialized to 0, and each of the program object's active uniform variables will be assigned a location that can be queried by calling GetUniformLocation. Also, any active user-defined attribute variables that have not been bound to a generic vertex attribute index will be bound to one at this time.

Linking of a program object can fail for a number of reasons as specified in the OpenGL Shading Language Specification. The following lists some of the conditions that will cause a link error.

  • The number of active attribute variables supported by the implementation has been exceeded.

  • The storage limit for uniform variables has been exceeded.

  • The number of active uniform variables supported by the implementation has been exceeded.

  • The main function is missing for the vertex shader or the fragment shader.

  • A varying variable actually used in the fragment shader is not declared in the same way (or is not declared at all) in the vertex shader.

  • A reference to a function or variable name is unresolved.

  • A shared global is declared with two different types or two different initial values.

  • One or more of the attached shader objects has not been successfully compiled.

  • Binding a generic attribute matrix caused some rows of the matrix to fall outside the allowed maximum of GL.MAX_VERTEX_ATTRIBS.

  • Not enough contiguous vertex attribute slots could be found to bind attribute matrices.

When a program object has been successfully linked, the program object can be made part of current state by calling UseProgram. Whether or not the link operation was successful, the program object's information log will be overwritten. The information log can be retrieved by calling GetProgramInfoLog.

LinkProgram will also install the generated executables as part of the current rendering state if the link operation was successful and the specified program object is already currently in use as a result of a previous call to UseProgram. If the program object currently in use is relinked unsuccessfully, its link status will be set to GL.FALSE , but the executables and associated state will remain part of the current state until a subsequent call to UseProgram removes it from use. After it is removed from use, it cannot be made part of current state until it has been successfully relinked.

If program contains shader objects of type GL.VERTEX_SHADER but does not contain shader objects of type GL.FRAGMENT_SHADER, the vertex shader will be linked against the implicit interface for fixed functionality fragment processing. Similarly, if program contains shader objects of type GL.FRAGMENT_SHADER but it does not contain shader objects of type GL.VERTEX_SHADER, the fragment shader will be linked against the implicit interface for fixed functionality vertex processing.

The program object's information log is updated and the program is generated at the time of the link operation. After the link operation, applications are free to modify attached shader objects, compile attached shader objects, detach shader objects, delete shader objects, and attach additional shader objects. None of these operations affects the information log or the program that is part of the program object.

If the link operation is unsuccessful, any information about a previous link operation on program is lost (a failed link does not restore the old state of program). Certain information can still be retrieved from program even after an unsuccessful link operation. See for instance GetActiveAttrib and GetActiveUniform.

Error GL.INVALID_VALUE is generated if program is not a value generated by OpenGL. GL.INVALID_OPERATION is generated if program is not a program object. GL.INVALID_OPERATION is generated if LinkProgram is executed between the execution of Begin and the corresponding execution of End.

LinkProgram is available in GL version 2.0 or greater.

func (*GL) MultMatrixd

func (gl *GL) MultMatrixd(m []float64)

MultMatrixd multiplies the current matrix with the provided matrix.

The m parameter must hold 16 consecutive elements of a 4x4 column-major matrix.

The current matrix is determined by the current matrix mode (see MatrixMode). It is either the projection matrix, modelview matrix, or the texture matrix.

For example, if the current matrix is C and the coordinates to be transformed are v = (v[0], v[1], v[2], v[3]), then the current transformation is C × v, or

c[0]  c[4]  c[8]  c[12]     v[0]
c[1]  c[5]  c[9]  c[13]     v[1]
c[2]  c[6]  c[10] c[14]  X  v[2]
c[3]  c[7]  c[11] c[15]     v[3]

Calling MultMatrix with an argument of m = m[0], m[1], ..., m[15] replaces the current transformation with (C X M) x v, or

c[0]  c[4]  c[8]  c[12]   m[0]  m[4]  m[8]  m[12]   v[0]
c[1]  c[5]  c[9]  c[13]   m[1]  m[5]  m[9]  m[13]   v[1]
c[2]  c[6]  c[10] c[14] X m[2]  m[6]  m[10] m[14] X v[2]
c[3]  c[7]  c[11] c[15]   m[3]  m[7]  m[11] m[15]   v[3]

Where 'X' denotes matrix multiplication, and v is represented as a 4x1 matrix.

While the elements of the matrix may be specified with single or double precision, the GL may store or operate on these values in less-than-single precision.

In many computer languages, 4×4 arrays are represented in row-major order. The transformations just described represent these matrices in column-major order. The order of the multiplication is important. For example, if the current transformation is a rotation, and MultMatrix is called with a translation matrix, the translation is done directly on the coordinates to be transformed, while the rotation is done on the results of that translation.

GL.INVALID_OPERATION is generated if MultMatrix is executed between the execution of Begin and the corresponding execution of End.

func (*GL) MultMatrixf

func (gl *GL) MultMatrixf(m []float32)

MultMatrixf multiplies the current matrix with the provided matrix.

The m parameter must hold 16 consecutive elements of a 4x4 column-major matrix.

The current matrix is determined by the current matrix mode (see MatrixMode). It is either the projection matrix, modelview matrix, or the texture matrix.

For example, if the current matrix is C and the coordinates to be transformed are v = (v[0], v[1], v[2], v[3]), then the current transformation is C × v, or

c[0]  c[4]  c[8]  c[12]     v[0]
c[1]  c[5]  c[9]  c[13]     v[1]
c[2]  c[6]  c[10] c[14]  X  v[2]
c[3]  c[7]  c[11] c[15]     v[3]

Calling MultMatrix with an argument of m = m[0], m[1], ..., m[15] replaces the current transformation with (C X M) x v, or

c[0]  c[4]  c[8]  c[12]   m[0]  m[4]  m[8]  m[12]   v[0]
c[1]  c[5]  c[9]  c[13]   m[1]  m[5]  m[9]  m[13]   v[1]
c[2]  c[6]  c[10] c[14] X m[2]  m[6]  m[10] m[14] X v[2]
c[3]  c[7]  c[11] c[15]   m[3]  m[7]  m[11] m[15]   v[3]

Where 'X' denotes matrix multiplication, and v is represented as a 4x1 matrix.

func (*GL) Uniform1f

func (gl *GL) Uniform1f(location glbase.Uniform, v0 float32)

Uniform1f modifies the value of a single uniform variable. The location of the uniform variable to be modified is specified by location, which should be a value returned by GetUniformLocation. Uniform1f operates on the program object that was made part of current state by calling UseProgram.

The functions Uniform{1|2|3|4}{f|i|ui} are used to change the value of the uniform variable specified by location using the values passed as arguments. The number specified in the function should match the number of components in the data type of the specified uniform variable (1 for float, int, unsigned int, bool; 2 for vec2, ivec2, uvec2, bvec2, etc.). The suffix f indicates that floating-point values are being passed; the suffix i indicates that integer values are being passed; the suffix ui indicates that unsigned integer values are being passed, and this type should also match the data type of the specified uniform variable. The i variants of this function should be used to provide values for uniform variables defined as int, ivec2, ivec3, ivec4, or arrays of these. The ui variants of this function should be used to provide values for uniform variables defined as unsigned int, uvec2, uvec3, uvec4, or arrays of these. The f variants should be used to provide values for uniform variables of type float, vec2, vec3, vec4, or arrays of these. Either the i, ui or f variants may be used to provide values for uniform variables of type bool, bvec2, bvec3, bvec4, or arrays of these. The uniform variable will be set to false if the input value is 0 or 0.0f, and it will be set to true otherwise.

Uniform1i and Uniform1iv are the only two functions that may be used to load uniform variables defined as sampler types. Loading samplers with any other function will result in a GL.INVALID_OPERATION error.

If m + n - 1 is larger than the size of the uniform variable array, values for all array elements beyond the end of the array will be ignored. The number specified in the name of the command indicates the number of components for each element in value, and it should match the number of components in the data type of the specified uniform variable (1 for float, int, bool; 2 for vec2, ivec2, bvec2, etc.). The data type specified in the name of the command must match the data type for the specified uniform variable as described for Uniform{1|2|3|4}{f|i|ui}.

Uniform1i and Uniform1iv are the only two functions that may be used to load uniform variables defined as sampler types. Loading samplers with any other function will result in a GL.INVALID_OPERATION error.

All active uniform variables defined in a program object are initialized to 0 when the program object is linked successfully. They retain the values assigned to them by a call to Uniform* until the next successful link operation occurs on the program object, when they are once again initialized to 0.

func (*GL) Uniform4i

func (gl *GL) Uniform4i(location glbase.Uniform, v0, v1, v2, v3 int32)

Uniform4i modifies the value of a single uniform variable. The location of the uniform variable to be modified is specified by location, which should be a value returned by GetUniformLocation. Uniform4i operates on the program object that was made part of current state by calling UseProgram.

The functions Uniform{1|2|3|4}{f|i|ui} are used to change the value of the uniform variable specified by location using the values passed as arguments. The number specified in the function should match the number of components in the data type of the specified uniform variable (1 for float, int, unsigned int, bool; 2 for vec2, ivec2, uvec2, bvec2, etc.). The suffix f indicates that floating-point values are being passed; the suffix i indicates that integer values are being passed; the suffix ui indicates that unsigned integer values are being passed, and this type should also match the data type of the specified uniform variable. The i variants of this function should be used to provide values for uniform variables defined as int, ivec2, ivec3, ivec4, or arrays of these. The ui variants of this function should be used to provide values for uniform variables defined as unsigned int, uvec2, uvec3, uvec4, or arrays of these. The f variants should be used to provide values for uniform variables of type float, vec2, vec3, vec4, or arrays of these. Either the i, ui or f variants may be used to provide values for uniform variables of type bool, bvec2, bvec3, bvec4, or arrays of these. The uniform variable will be set to false if the input value is 0 or 0.0f, and it will be set to true otherwise.

Uniform1i and Uniform1iv are the only two functions that may be used to load uniform variables defined as sampler types. Loading samplers with any other function will result in a GL.INVALID_OPERATION error.

They retain the values assigned to them by a call to Uniform* until the next successful link operation occurs on the program object, when they are once again initialized to 0.

func (*GL) Uniform4iv

func (gl *GL) Uniform4iv(location glbase.Uniform, value []int32)

Uniform4iv modifies the value of a uniform variable or a uniform variable array. The location of the uniform variable to be modified is specified by location, which should be a value returned by GetUniformLocation. Uniform4iv operates on the program object that was made part of current state by calling UseProgram.

The functions Uniform{1|2|3|4}{f|i|ui}v can be used to modify a single uniform variable or a uniform variable array. These functions receive a slice with the values to be loaded into a uniform variable or a uniform variable array. A slice with length 1 should be used if modifying the value of a single uniform variable, and a length of 1 or greater can be used to modify an entire array or part of an array. When loading n elements starting at an arbitrary position m in a uniform variable array, elements m + n - 1 in the array will be replaced with the new values. If m + n - 1 is larger than the size of the uniform variable array, values for all array elements beyond the end of the array will be ignored.

func (*GL) UniformMatrix2fv

func (gl *GL) UniformMatrix2fv(location glbase.Uniform, transpose bool, value []float32)

UniformMatrix2fv modifies the value of a uniform variable or a uniform variable array. The location of the uniform variable to be modified is specified by location, which should be a value returned by GetUniformLocation. UniformMatrix2fv operates on the program object that was made part of current state by calling UseProgram.

The functions UniformMatrix{2|3|4|2x3|3x2|2x4|4x2|3x4|4x3}fv are used to modify a matrix or an array of matrices. The numbers in the function name are interpreted as the dimensionality of the matrix. The number 2 indicates a 2x2 matrix (4 values), the number 3 indicates a 3x3 matrix (9 values), and the number 4 indicates a 4x4 matrix (16 values). Non-square matrix dimensionality is explicit, with the first number representing the number of columns and the second number representing the number of rows. For example, 2x4 indicates a 2x4 matrix with 2 columns and 4 rows (8 values). The length of the provided slice must be a multiple of the number of values per matrix, to update one or more consecutive matrices.

If transpose is false, each matrix is assumed to be supplied in column major order. If transpose is true, each matrix is assumed to be supplied in row major order.

func (*GL) UseProgram

func (gl *GL) UseProgram(program glbase.Program)

UseProgram installs the program object specified by program as part of current rendering state. One or more executables are created in a program object by successfully attaching shader objects to it with AttachShader, successfully compiling the shader objects with CompileShader, and successfully linking the program object with LinkProgram.

A program object will contain an executable that will run on the vertex processor if it contains one or more shader objects of type GL.VERTEX_SHADER that have been successfully compiled and linked. Similarly, a program object will contain an executable that will run on the fragment processor if it contains one or more shader objects of type GL.FRAGMENT_SHADER that have been successfully compiled and linked.

Successfully installing an executable on a programmable processor will cause the corresponding fixed functionality of OpenGL to be disabled. Specifically, if an executable is installed on the vertex processor, the OpenGL fixed functionality will be disabled as follows.

  • The modelview matrix is not applied to vertex coordinates.

  • The projection matrix is not applied to vertex coordinates.

  • The texture matrices are not applied to texture coordinates.

  • Normals are not transformed to eye coordinates.

  • Normals are not rescaled or normalized.

  • Normalization of GL.AUTO_NORMAL evaluated normals is not performed.

  • Texture coordinates are not generated automatically.

  • Per-vertex lighting is not performed.

  • Color material computations are not performed.

  • Color index lighting is not performed.

  • This list also applies when setting the current raster position.

The executable that is installed on the vertex processor is expected to implement any or all of the desired functionality from the preceding list. Similarly, if an executable is installed on the fragment processor, the OpenGL fixed functionality will be disabled as follows.

  • Texture environment and texture functions are not applied.

  • Texture application is not applied.

  • Color sum is not applied.

  • Fog is not applied.

Again, the fragment shader that is installed is expected to implement any or all of the desired functionality from the preceding list.

While a program object is in use, applications are free to modify attached shader objects, compile attached shader objects, attach additional shader objects, and detach or delete shader objects. None of these operations will affect the executables that are part of the current state. However, relinking the program object that is currently in use will install the program object as part of the current rendering state if the link operation was successful (see LinkProgram). If the program object currently in use is relinked unsuccessfully, its link status will be set to GL.FALSE, but the executables and associated state will remain part of the current state until a subsequent call to UseProgram removes it from use. After it is removed from use, it cannot be made part of current state until it has been successfully relinked.

If program contains shader objects of type GL.VERTEX_SHADER but it does not contain shader objects of type GL.FRAGMENT_SHADER, an executable will be installed on the vertex processor, but fixed functionality will be used for fragment processing. Similarly, if program contains shader objects of type GL.FRAGMENT_SHADER but it does not contain shader objects of type GL.VERTEX_SHADER, an executable will be installed on the fragment processor, but fixed functionality will be used for vertex processing. If program is 0, the programmable processors will be disabled, and fixed functionality will be used for both vertex and fragment processing.

While a program object is in use, the state that controls the disabled fixed functionality may also be updated using the normal OpenGL calls.

Like display lists and texture objects, the name space for program objects may be shared across a set of contexts, as long as the server sides of the contexts share the same address space. If the name space is shared across contexts, any attached objects and the data associated with those attached objects are shared as well.

Applications are responsible for providing the synchronization across API calls when objects are accessed from different execution threads.

Error GL.INVALID_VALUE is generated if program is neither 0 nor a value generated by OpenGL. GL.INVALID_OPERATION is generated if program is not a program object. GL.INVALID_OPERATION is generated if program could not be made part of current state. GL.INVALID_OPERATION is generated if UseProgram is executed between the execution of Begin and the corresponding execution of End.

UseProgram is available in GL version 2.0 or greater.

func (*GL) VertexAttribPointer

func (gl *GL) VertexAttribPointer(index glbase.Attrib, size int, gltype glbase.Enum, normalized bool, stride int, offset uintptr)

VertexAttribPointer specifies the location and data format of the array of generic vertex attributes at index to use when rendering. size specifies the number of components per attribute and must be 1, 2, 3, or 4. type specifies the data type of each component, and stride specifies the byte stride from one attribute to the next, allowing vertices and attributes to be packed into a single array or stored in separate arrays. normalized indicates whether the values stored in an integer format are to be mapped to the range [-1,1] (for signed values) or [0,1] (for unsigned values) when they are accessed and converted to floating point; otherwise, values will be converted to floats directly without normalization. offset is a byte offset into the buffer object's data store, which must be bound to the GL.ARRAY_BUFFER target with BindBuffer.

The buffer object binding (GL.ARRAY_BUFFER_BINDING) is saved as generic vertex attribute array client-side state (GL.VERTEX_ATTRIB_ARRAY_BUFFER_BINDING) for the provided index.

To enable and disable a generic vertex attribute array, call EnableVertexAttribArray and DisableVertexAttribArray with index. If enabled, the generic vertex attribute array is used when DrawArrays or DrawElements is called. Each generic vertex attribute array is initially disabled.

VertexAttribPointer is typically implemented on the client side.

Error GL.INVALID_ENUM is generated if type is not an accepted value. GL.INVALID_VALUE is generated if index is greater than or equal to GL.MAX_VERTEX_ATTRIBS. GL.INVALID_VALUE is generated if size is not 1, 2, 3, or 4. GL.INVALID_VALUE is generated if stride is negative.
