LuxCoreRender Forums

Hi! I just want to be sure that I understand it correctly: in Disney, we don't make real transmission/subsurface scattering, we just fake it according to empirical laws? I just wonder about this https://blog.selfshadow.com/publication ... slides.pdf (page 20). Is it just a combination with "rea...

Good advice! I'm going to do this way

Thanks, Dade! It sounds really interesting. I think it is a good topic just to begin with!

I guess PBRT v3 has already Disney 2015 implementation in the source code: https://github.com/mmp/pbrt-v3/blob/mas ... disney.cpp

Hope i can dig into on Weekend

Hi all! I would like to help with LuxCoreRender development. I used to work with the old version of LuxRender (I've done some kind of illuminance sensor and custom color map. Haven't ever pushed it), but I have not so much experience with the modern version (looks like the code has changed a lot). I...

Hey Dade, thank you for the explanation.

I hope, I could help a bit with luxcorerender development (I've done something like an illuminance sensor for old good lux render, but never try to push it into the repository). I'll put my note into "LuxCoreRender Project wants you!" topic

Wow, thanks for the clear explanation! I just wonder how do you combine rays emission/intersection/shading/shadowing on GPU side? Is it something like Wavefront Path Tracing used in PBRT (https://research.nvidia.com/sites/default/files/pubs/2013-07_Megakernels-Considered-Harmful/laine2013hpg_paper.p...

Hi all, I just wonder which engines uses OptiX intersection acceleration? I've made a couple of breakpoints in OptiX initialization code (optixaccel and optixaccelhw) and it stops only for OpenCl engines. Do CPU engines using OptiX intersection? The other question: how OpenCl code and OptiX are work...
