Taking the above tutorial one step further, this tutorial deals with polygon collision.  There's a big difference.  This will tell you if a line segment intersects the actual polygon instead of the entire plane in which the polygon lies.

Functions Used:  glViewport(), glMatrixMode(), glLoadIdentity(), gluPerspective(), glClear(), gluLookAt(), glBegin(), glEnd(), SwapBuffers(), sqrt(), arcos(), _isnan()
