Re: Moving ompf2 to a new host

Quick update:
For some reason we are still on the old host. I am investigating what went wrong; the promised 5 days have passed.

Major maintenance coming up

Hi all, FYI: Update on the previous post: a domain transfer request is being processed. I sadly cannot setup PHPBB on a temporary domain, so I need to do this when the transfer completes. This reportedly takes between 2 and 5 days. If the move comes through today or tomorrow morning I can setup the ...

Moving ompf2 to a new host

Hi all, For the past couple of years, ompf2 was kindly hosted on the servers of the NHTV university of applied sciences, even after I moved to a different university. About a year ago, we had to disable outgoing email for the board, as it was generating spam. This effectively means that new users ca...

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...

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...
