Small volumetric path tracer

[dbz]

Interesting. How is the performance on cuda?

[D-POWER]

It depends on the scene, but on average there is 8 to 9 times speedup on my nvidia GT220

Looks Nice,

And have you also fixed the version on the git repository ? Or upload the cuda version ?

[D-POWER]

I have just upload the new source code. Though, keep in mind that the source code is still experimental and lacks proper optimization, considering that my cuda knowledge is quite limited

EDIT: here is the link to the github repository https://github.com/D-POWER/vpath

Sure,

It is just to give a try and review...

Thx

[D-POWER]

Any suggestions/improvements is very welcome. I'm always looking for techniques to squeeze more speed

[spectral]

I haven't take a closer look,

But this project seems to implement SSS to and support more kind of primitives : http://gpupathtracer.blogspot.be/

Maybe take a look

Yes, I'm aware of Peter and Karl's gpu path tracer, actually it inspired me a lot in writing my own volumetric path tracer

D-Power, I hope you don't mind I borrowed your idea of applying scattering to SmallPT and I added this features to the good old SmallPTGPU (an OpenCL version of Kevin Beason's SmallPT available here http://code.google.com/p/ocltoys/):
