Functions ¶

func CompileShader ¶

func CompileShader(source string, shaderType uint32) (uint32, error)

func DrawImage ¶

func DrawImage(windowWidth, windowHeight int, img image.Image, imageRectSpecs RectSpecs)

You must have initialized glfw and gl before using this function

func InRectSpecs ¶

func InRectSpecs(rectSpecs RectSpecs, xPos, yPos int) bool

useful for mouse events
