Hi Guy's

I am a bit new at programming on CUDA. I am working on a hobby project, a path tracer. I was wondering how you guy's deal with CUDA.

Do you guys perform all graphics related computing on the GPU or is it more of a hybrid approach? For instance performing ray intersection test on the GPU and doing the BSDFs on the CPU (host)?

I hope you can answer my questions since I am curious how applications like yours and for instance Arion deal with this.

Thanks in advance,

Thomas Kroes

As this is commercial software I doubt you are going to get much information on how it works/is made.

Yeah, sorry, it's our policy not to talk about internals.
What i can say is that octane's raytracer runs entirely on the GPU.
The CPU only does IO and user interface.

I think, this is the winning point of Octane.
