Lighting problems in OpenGL
Author
In the demo from Bruno I saw that there was strange lighting when looking at different angles.
I''ve got the same problem and I don''t know how to get normal lighting.
Please help me because I''ve been searching for a week now and I still don''t know how to fix it!
Can you add a link to Bruno''s demo? I don''t read all threads (probably more people don''t).
I wasn''t defining any normals in the demo... Opengl was doing the lighning the way he wanted.
You have to define normals for each polygon on the scene.
Take a look at the NEHE tutorials.. he teaches how to define normals for a cube.

zedzeek: no, I only position the light when initializing OGL.
Bruno: When loading an object I define the normals too, I think I'm doing something wrong.

It works! 
My normals were good, but I didn''t update the light each frame (after the camera).
Thanks for the replies, they helped me very much!
