func Init

func Init() error

Init initializes the OpenGL bindings by loading the function pointers (for each OpenGL function) from the active OpenGL context.

It must be called under the presence of an active OpenGL context, e.g., always after calling window.MakeContextCurrent() and always before calling any OpenGL functions exported by this package.

On Windows, Init loads pointers that are context-specific (and hence you must re-init if switching between OpenGL contexts, although not calling Init again after switching between OpenGL contexts may work if the contexts belong to the same graphics driver/device).

On macOS and the other POSIX systems, the behavior is different, but code written compatible with the Windows behavior is compatible with macOS and the other POSIX systems. That is, always Init under an active OpenGL context, and always re-init after switching graphics contexts.

For information about caveats of Init, you should read the "Platform Specific Function Retrieval" section of https://www.opengl.org/wiki/Load_OpenGL_Functions.

func InitWithProcAddrFunc

func InitWithProcAddrFunc(getProcAddr func(name string) unsafe.Pointer) error

InitWithProcAddrFunc intializes the package using the specified OpenGL function pointer loading function. For more cases Init should be used instead.

func PixelStorei

func PixelStorei(pname uint32, param int32)

func PolygonOffset

func PolygonOffset(factor float32, units float32)

func Ptr

func Ptr(data interface{}) unsafe.Pointer

Ptr takes a slice or pointer (to a singular scalar value or the first element of an array or slice) and returns its GL-compatible address.

For example:

var data []uint8
...
gl.TexImage2D(gl.TEXTURE_2D, ..., gl.UNSIGNED_BYTE, gl.Ptr(&data[0]))

func PtrOffset

func PtrOffset(offset int) unsafe.Pointer

PtrOffset takes a pointer offset and returns a GL-compatible pointer. Useful for functions such as glVertexAttribPointer that take pointer parameters indicating an offset rather than an absolute memory address.

func ReadPixels

func ReadPixels(x int32, y int32, width int32, height int32, format uint32, xtype uint32, pixels unsafe.Pointer)

func StencilOpSeparate

func Str

func Str(str string) *uint8

Str takes a null-terminated Go string and returns its GL-compatible address. This function reaches into Go string storage in an unsafe way so the caller must ensure the string is not garbage collected.

func Strs

func Strs(strs ...string) (cstrs **uint8, free func())

Strs takes a list of Go strings (with or without null-termination) and returns their C counterpart.

The returned free function must be called once you are done using the strings in order to free the memory.

If no strings are provided as a parameter this function will panic.
