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.

Uniform4i writes an ivec4 uniform variable.

func (Uniform) I4v 

func (dst Uniform) I4v(src []int32)

Uniform4i writes an ivec4 uniform array of len(src)/4 elements.

func (Uniform) Iv 

func (dst Uniform) Iv(src []int32)

Uniform1iv writes a int uniform array of len(src) elements.

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 INVALID_OPERATION error.

func (Uniform) Matrix2fv 

func (dst Uniform) Matrix2fv(src []float32)

UniformMatrix2fv writes 2x2 matrices. Each matrix uses four float32 values, so the number of matrices written is len(src)/4.

Each matrix must be supplied in column major order.

http://www.khronos.org/opengles/sdk/docs/man3/html/glUniform.xhtml

func (Uniform) Matrix3fv 

func (dst Uniform) Matrix3fv(src []float32)

UniformMatrix3fv writes 3x3 matrices. Each matrix uses nine float32 values, so the number of matrices written is len(src)/9.

Each matrix must be supplied in column major order.

http://www.khronos.org/opengles/sdk/docs/man3/html/glUniform.xhtml

func (Uniform) Matrix4fv 

func (dst Uniform) Matrix4fv(src []float32)

UniformMatrix4fv writes 4x4 matrices. Each matrix uses 16 float32 values, so the number of matrices written is len(src)/16.

Each matrix must be supplied in column major order.
