This OpenGL sample shows how to draw a plane in 3d using your mouse. Also explains how to transform mouse coordinates to 3d world coordinates. This tutorial shows the connection between 'glulookat' command, mouse position on the screen and 3d world coordinates. This example will get you familiar with the gluunproject perspective projection, ray picking and the use of glreadpixels. Also explains the glulookat implementation, the right mathematical formula to use, the correct matrix projection and givesĀ a connection between these commands. Get full OpenGL source.
