Why do you get soft shadows for free? Normal ray tracing has hard shadows.

iztok,
being raytraced have nothing to do with soft shadows. It's raytraced because it takes a list of objects and computes visibility by checking whether the line from the fragment to the light intersects a sphere.

Spiff,
set desktop bitdepth to 32 or use fullscreen.

This is only really meant for simple objects such as spheres. It doesn't apply to complex models. I'm thinking of writing a raytracing demo for more complex shapes, but it will likely be slower than shadow mapping and stencil shadows and still only be hard shadows.

No shadows on my 5950 either. ATI whore!
