Hello, I got some example shadow mapping code and have finally managed to simplify it to a point where what is going on is actually obvious. The code was part of a demo, which I have tried to keep mostly the same. The demo uses two objects, a strange purple thing and a green landscape. The shadow mapping works, but only with these two objects. The objects are loaded into a display list. When I substitute my objects in the same place, the mapping breaks down: Why is it that even though the objects are display lists, the one that came with the demo works and the one that I made didn't. What can I do to fix my display lists so that they work with this algorithm? I present my python source code: www.geometrian.com/shadowmapping.zip Run Game.py Line 121 loads the floor which came with the demo. Line 122 loads my floor. Line 123 loads the object which came with the demo. Line 124 loads my object. Thanks, Geometrian
