comment Opengl lighting not working
In that case, I usually find that the normals are not calculated properly or the light is not close enough. I would add some temporary controls to move the light around while the program is running and log the coordinates for you. If that does not work, I don't know what to tell you.

If it is a dark grey and not just black, then you only need to adjust the light settings. If it is black, I cannot help because the code looks fine. Maybe you could include a little more for us?

comment GLSL code is very slow…why?
This app draws only a little bit more, but surely not enough for a big drop in fps.

comment GLSL code is very slow…why?
Because I copied all of the other relevant code from one of my other apps, which functions very well.

comment GLSL code is very slow…why?
I call it once per texture when the application starts. That is all. That is why I am so confused.

comment GLSL light coloring blocked surfaces
I am working on implementing this now. That second tutorial is very thorough and geared toward beginners, so it is already giving me nice results. I've also combined the multisample and shadow shaders and buffers, so performance is now barely effected! Can you add this as an answer so I can mark it?

That is not what I said. I simply said I would prefer that. I am open to doing whatever I need to.

comment GLSL light coloring blocked surfaces
I have found a bit of a problem with that. As the scene rotates, the light appears to illuminate things differently. Instead of giving me a smooth, circular lighting pattern, it seems to simply apply light in a cone shape from the center of each object to the edge pointing toward the light. You would expect that, but while the objects and the light are not moving, the lighting patter changes based on the rotation and scaling of the matrices.
