Re: My Optix porting of SmallVCM (only PathTracer & BDPT)

Hi Emphy, you can download the full sources from here, but I have no much time to give you details about the implementation (that however is a straightforward porting of the SmallVCM's bidirectional path-tracer): https://docs.google.com/file/d/0B5XiKsI39CvcWkZ1alNncTIxM1E/ Environment used: - Window...

Boosting Monte Carlo Rendering by Ray Histogram Fusion

Hey guys, good news: http://dev.ipol.im/~mdelbra/rhf/ "Boosting Monte Carlo Rendering by Ray Histogram Fusion" "This paper proposes a new multi-scale filter accelerating Monte Carlo renderers. [...] This simple and easily reproducible algorithm provides a PSNR gain of 10 to 15 decibels, or equivalen...

Re: My Optix porting of SmallVCM (only PathTracer & BDPT)

You should look at the Streaming Bidirectional path tracing (Chapter 8) from Dietger van Antwerpen: http://repository.tudelft.nl/view/ir/uuid:4a5be464-dc52-4bd0-9ede-faefdaff8be6/ Actually it's better read the whole thesis ;). Hi, thanks for this link, it's hard to find a publication with so many d...

Ah, ok, so probably it use both (pressing 'p' (lowecase) the number of devices should decrease)...

Re: My Optix porting of SmallVCM (only PathTracer & BDPT)

Ah... I forgot... GTX690 is a dual GPU, you have to press the 'P' (uppercase!) key to increase the number of devices used (I'm not sure if Optix automatically use both)...

Re: My Path Tracer + Bidirectional Path Tracer

50 FPS for the path tracer... looks really better ;-) But as you know, there is more "math" stuffs with the BDPT and also more divergence because of additional lights path... so, doing a fast PT is simple... but doing a BDPT with the same speed... I'm not sure it is possible ! Yes, BDPT shoot more ...

Re: My Path Tracer + Bidirectional Path Tracer

Hi, Yes it was with 3.5 ! It works with 3.0 but looks VERY VERY SLOW !! I got 4 FPS on a GTX690 I have try to reproduce your test scene in our GPU renderer, it use a kind of BDPT too... and is not optimized yet (For the next version) ! 47 FPS ! And with our new path tracer (no caustics) we got 200 ...

Re: My Path Tracer + Bidirectional Path Tracer

Ok, some people report crash on the 3.5 version. It's strange, because I have simply recompiled the code using the compute model 3.5 (as for the other two versions). Looks like a CUDA 5.0 compiler bug (unfortunately it's not the first I discover...). I'm going to post this on the nVidia Developer Fo...

Which version have you tried? At least the SM2.0 works on my video card: nVidia Geforce 555M 2Gb.

My Optix porting of SmallVCM (only PathTracer & BDPT)

Hi all, I have implemented a Path Tracer and a Bidirectional Path Tracer based on the brilliant SmallVCM code using Optix 3.0.1 (I'm going to update it with the fresh new Optix 3.5). You can download the demos here (based on your compute capability): Pathtracer SM2.0: https://drive.google.com/file/d...
