Re: Optix 6.0 Path Tracing demo

Well I think this deserves its own topic. :) I don't handle this at all; the demo uses unidirectional path tracing only, no photon mapping. But what I got for photon mapping is: lightcolor * dot( D, N ) / lightPdf, where D is a cosine-weighted random direction with pdf = (dot( D, N ) / PI) / lightAr...

Re: Optix 6.0 Path Tracing demo

Please go ahead. But I think this is straight from McGuire's page?

Optix 6.0 Path Tracing demo

Hi all, Since the release of Optix 6.0 a few weeks ago I have been playing a bit with the new RTX support. Here's a demo that should run on Maxwell, Pascal and Turing, which allows a direct comparison of the ray tracing performance of these platforms. Spoiler: Turing fares well. http://www.cs.uu.nl/...

Re: CUDA 10 available

It looks like we'll only be able to access the ray tracing hardware via OptiX / Vulcan / DX12. No CUDA. If your renderer is implemented in CUDA, you can call OptiX from CUDA, but you don't get to use the hardware directly. Add to that that this is a feature promised for Optix 5.2, which is not avail...

Re: Something's wrong with the RSS and forum posting

It's back to http. Should be better now.
EDIT: that didn't solve it. :(
EDIT2: now it seems to be working.
EDIT3: now also with https, by deselecting something about forcing https. I did it. :ugeek:

Re: Something's wrong with the RSS and forum posting

The domain was recently transferred to me (it was being paid for by my previous employer, and the files are still hosted there), and in the process we moved to https. That's the only change that could have caused this. I am not sure if the https has any benefits (for us), so I will turn it off for n...
