Another nice and detailed demo Humus! What I've noticed in the last few demos with offset bumpmapping and bumpmap self shadowing is that the shadow maps look very sharp. They look almost as if shadow volumes were used.

Looks good, nice work

I'm curious about one thing though... if shadows, compressed bump maps and compressed base maps are all set to false I get about 75 fps. Enabling only compressed bump maps gives a nice boost to about 90 fps, and enabling only compressed base maps gives me about 93 fps. The weird thing (I think, I've never done any 3D programming) is that with both compressed bump maps and compressed base maps enabled, I get 91 fps. Granted it's not a big difference, but it does make me curious. Individually they both give a nice performance boost, but shouldn't the boost get bigger when using both? I see the same pattern with shadows enabled, only the numbers are lower.

This is with a Radeon 9800 Pro and Catalyst 4.6 drivers if it matters

I think humus has a cubic shadow mapping demo in OpenGL on this site (shadows that rocks?) Anyway it uses the "packing a float into a color texture" hack to accomplish this.

There is also another demo of this "hack" at:

Sure you can! You don't need to use depth textures, you can just use any regular texture format and shaders.

Looks greate!

BTW, currently it is not possible to use cubic shadow mapping in OpenGL, right?
AFAIK, GL_DEPTH_COMPONENT format is not supported under GL_TEXTURE_CUBE_MAP_ARB redner target.
