colorMaterial $= Enabled colorMaterial $= Just (FrontAndBack, AmbientAndDiffuse)
Something's wrong. I don't think that should typecheck. IIUC setting colorMaterial to Just or Nothing enables or disables it respectively.
Yes, this is a type error. I forgot to remove it. Normalizing the normals and shutting off specular improved the scene the most. Thanks!
A number of different things could be going wrong. To simplify things:
* Set the light source position to Vector4 1 1 0 0 <-- note the last zero This makes the light source infinite, which is a simpler lighting model.
* Turn the specular lighting to zero, also for a simpler lighting model.
(When you use specular and point lighting at the same time, you usually also want to enable lightModelLocalViewer, but hold off until you have the basics working.)
* Turn colorMaterial off, and just use a plain blue sphere (e.g. glutSolidSphere).
* Follow the advice on the other thread about enabling GL_NORMALIZE.
As you turn off features, you should see something conspicuous that illuminates (sorry) the problem.
Once you have a scene that looks reasonable, you can start re-enabling features one by one.
