Re: Fujiyama Renderer

Thanks for your reply,

I'm surprised they have let you work on your own personal renderer. About the code, is it possible to make it compile on Windows without any substantial change?

Re: Fujiyama Renderer

Interesting piece of software. However, I would be more glad if it was open source. I have a couple of questions to ask: How long have you been developing Fujiyama? Was it developed inside Digital Domain as an in-house renderer? If yes, was it used in a real production movie? Can you share some impl...

Re: Psychopath: a microgeometry path tracer

Cool project! You're the guy who worked on Big Bugs Bunny and probably many other feature films from the Blender Foundation. I never knew that you are also a programmer :)

Re: Small volumetric path tracer

By the way, what's the maximum depth did you use when rendering SSS? In my implementation https://github.com/D-POWER/vpath, I noticed that small values didn't work and I needed to use like 100 or even 200 as the maximum recursion depth.

Thanks

Re: Small volumetric path tracer

Of course I don't mind. That's some very cool renders you've got there :)
I think you should also update this page: http://davibu.interfree.it/opencl/smallptgpu/smallptGPU.html

Re: Small volumetric path tracer

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

Re: Small volumetric path tracer

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

Re: Small volumetric path tracer

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