Where can I find good tutorial about glReadPixel or other code you would recommend to use. I bought 4 OpenGL Books, none of them have good tutorial for it. How do you get RGB or RGBA value number when you use a mouse and pick a color on a single pixel on openGL window? Please post full code for mouse and return RGB value here or post url address where I can download good tutorial Waldoo
