func DumpTexture

func DumpTexture(textureId gl.Texture) (*image.NRGBA, error)

func DumpTextureAsPng

func DumpTextureAsPng(textureId gl.Texture, outfile io.Writer) error

func DumpTextureAsPngFile

func DumpTextureAsPngFile(textureId gl.Texture, path string) error

func GetActiveTextureUnit

func GetActiveTextureUnit() gl.GLenum

func GetBindingsSet

func GetBindingsSet() map[string]int

func GetColorMatrix

func GetColorMatrix() []float64

func GetColours

func GetColours() map[string]string

func GetDepthRange

func GetDepthRange() (float64, float64)

Returns the current (near, far) values as set from the last glDepthRange call.

func GetFlagSet

func GetFlagSet() map[string]gl.GLenum

func GetMatrixMode

func GetMatrixMode() gl.GLenum

Returns an enum denoting the current matrix mode.

func GetModelViewMatrix

func GetModelViewMatrix() []float64

func GetProjectionMatrix

func GetProjectionMatrix() []float64

func GetTextureMatrix

func GetTextureMatrix() []float64

func GetViewport

func GetViewport() (int32, int32, uint32, uint32)

Returns (x-pos, y-pos, width, height) of the current viewport.

func ScreenShot

func ScreenShot(width, height int, out io.Writer)

func ScreenShotNrgba

func ScreenShotNrgba(width, height int) *image.NRGBA
