Raytrace/reflections

Has anybody actually managed to make a raytrace shader in 3dgs?

I don't think they are possible with the first pixelshader version.

I don't think that realtime raytracing is even possible(I mean it's possible, but you'd have a framerate of 0.05). For reflections you could use a environment shader or you could use the camerafortexture (I think) function that's in the pro version. Realtime reflections aren't possible in 3DGS I think. I believe that's a directx 9 feature.

What about need for speed underground. Seemed like real raytracing.

it is possible to make (but not only using shaders): look out for the "still sucking on nature" or something like this title (its a demo and can be found at scene.org, i think. it provides nearly realtime raytracing (but it is dated 2001 if i am correct)

True raytracing would be pretty impractical, no? But flat mirror reflections, in conjunction with bump mapping would be great - Someone said this was possible with the professional version - this not only allows stunning water and wet surface reflections, but mirrors and glass as well.

You would think that a demo of this would go a long way to selling the pro version.. 3 cents.
