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:

(The portalengine demo)

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.

Nice work man. Sweet program

I tried running it in fullscreen on my x800XT PE and now I get an error saying "Couldn't creat Direct3D interface device". Even reinstalling the program doesn't fix it. Is there something I can use to find it in the registry to delete it? I tried searching for 3dc but that comes up with way too many items.

I must say this must be one of the best examples of detail normal mapping I have seen. (Think I saw the first just after Geforce3 was released, wonder why more people do not do it? -after people see this I am sure more will)

FYI- The shadows seem messed up on my 5200 (61.12 drivers). If they are enabled only ambient lighting seems to show up. And frame jumps from 7-1000(!) every second frame(timer bug?). Disabling shadows seems to make the demo run normally.
