"ray-traced clouds"

[chrisrt2]

I'm not too much into the technical side of the graphics world but I do remember massive arguments on these boards about whether next-gen or even just the PS3 would be able to support ray-tracing while maintaining acceptable performance... as it stands now the clouds in Warhawk are ray-traced...

Will ray-tracing be practical in other applications in other games? How about on the ‘360 or the Wii?

It looks like something Cell is well suited for. I imagine on XeCPU it'd consume too much resources needed for other things, but system wide, I really don't know. Maybe some such techniques do get used? Wii is unlikely to have the processing power needed for this.

They could have the Dust particles Ray Traced aswel in Warhawk.

We've been through this before - the clouds are most likely using simple raycasting, ie. rays are not bounced around and traced into the scene, so it is nowhere near as demanding as using raytraced reflections, refractions, or global illumination.

Laa-Yosh is right. I thought the OP was talking solely about RayTraced clouds, and don't mean to imply full raytracing scenes. Though with reported reflections and refractions in that Quantic Dreams demo, maybe they are using it on PS3 ?

Quantic dream demo has no reflection nor refraction ,except for static cubemaps here and here.
