Golang glGetShaderPrecisionFormat Examples

Example #1

File: es2.go Project: nick-fedesna/egles

func GetShaderPrecisionFormat(shadertype, precisiontype uint) (
	range_ int32, precision int32) {
	C.glGetShaderPrecisionFormat(
		C.GLenum(shadertype), C.GLenum(precisiontype),
		(*C.GLint)(&range_), (*C.GLint)(&precision))
	return
}

Example #2

File: gl_opengles.go Project: tanema/amore

func GetShaderPrecisionFormat(shadertype, precisiontype Enum) (rangeLow, rangeHigh, precision int) {
	const glintSize = 4
	var cRange [2]C.GLint
	var cPrecision C.GLint

	C.glGetShaderPrecisionFormat(shadertype.c(), precisiontype.c(), &cRange[0], &cPrecision)
	return int(cRange[0]), int(cRange[1]), int(cPrecision)
}

Example #3

File: gles2.go Project: remogatto/egles

	shadertype Enum, precisiontype Enum,
	range_ *int32, precision *int32) {
	C.glGetShaderPrecisionFormat(
		C.GLenum(shadertype),
		C.GLenum(precisiontype),
		(*C.GLint)(range_),
		(*C.GLint)(precision))
}
