I have the origins of a 3d engine working now, but in order to start on my game, I need to be able to display dialogs, and the mouse pointer using opengls raster graphics
My problem is this:
The glRasterPos2f function accepts x and y world coordinates, not screen/viewport pixels.
How do I convert between the two?
I want to display a pixmap at MouseX,MouseY,
and therefore need to perform this conversion.
