I've upload a new version. The shadows should work on nvidia now. I also improved dynamic branching performance a bit.

Yep, I get no shadows or light on my 6600GT.

The shadows do not work on nvidia cards in linux (driver version 87.56) unless I change the depth of the render target from 16 to 24.

Forgive my late comment on this great demo

I was interested how you did the omnidirectoral shadow mapping. Obviously it had to be cube maps or dual paraboloids. Cube maps, however, don't support depth maps to my knowledge.
From what I understood, you write the length of the light vector to a RBBA8 colour cubemap, and read the x coordinate in the pixel shader. At this point, it gets beyond my understanding. This is actually a 8bit depth value? 8bit depth?
Also, the shadow calculation atten *= float(dot(lVec, lVec) < shadow * shadow); is beyond my understanding. dot(lVec, lVec) == 1 for all values, and shadow*shadow is always less than 1 (unless distance was infinite), so this expression is equal to atten=0.0;? That can't be.
What is my mistake? I mean, it obviously *works* (as can be seen), but I am unable to understand why...
Thanks for your answer
