Golang GenBuffer Examples

Example #1

File: glimage.go Project: Miaque/mojo

func glInit() {
	var err error
	glimage.program, err = CreateProgram(vertexShader, fragmentShader)
	if err != nil {
		panic(err)
	}

	glimage.quadXY = gl.GenBuffer()
	glimage.quadUV = gl.GenBuffer()

	gl.BindBuffer(gl.ARRAY_BUFFER, glimage.quadXY)
	gl.BufferData(gl.ARRAY_BUFFER, gl.STATIC_DRAW, quadXYCoords)
	gl.BindBuffer(gl.ARRAY_BUFFER, glimage.quadUV)
	gl.BufferData(gl.ARRAY_BUFFER, gl.STATIC_DRAW, quadUVCoords)

	glimage.pos = gl.GetAttribLocation(glimage.program, "pos")
	glimage.mvp = gl.GetUniformLocation(glimage.program, "mvp")
	glimage.uvp = gl.GetUniformLocation(glimage.program, "uvp")
	glimage.inUV = gl.GetAttribLocation(glimage.program, "inUV")
	glimage.textureSample = gl.GetUniformLocation(glimage.program, "textureSample")
}

Example #2

File: main.go Project: xfong/gocl

func initGL() {
	var err error
	program, err = glutil.CreateProgram(vertexShader, fragmentShader)
	if err != nil {
		log.Printf("error creating GL program: %v", err)
		return
	}

	buf = gl.GenBuffer()
	gl.BindBuffer(gl.ARRAY_BUFFER, buf)
	gl.BufferData(gl.ARRAY_BUFFER, gl.STATIC_DRAW, triangleData)

	position = gl.GetAttribLocation(program, "position")
	color = gl.GetUniformLocation(program, "color")
	offset = gl.GetUniformLocation(program, "offset")
	touchLoc = geom.Point{geom.Width / 2, geom.Height / 2}
}
