Re: Adaptive Environment Sampling on CPU and GPU

It sounds like this does not only help with direct light like ELVC but indirect light also? Would this work with BiDir(VM) too? (Looks like a simple way of path guiding (MIS) to me.) Direct light sampling is done for each path vertex so after the first bounce, it contributes to indirect lighting to...

Hopefully this also means the region/border rendering will work much better too
It is not related. It has a different explanation and an easy workaround.

Re: Adaptive Environment Sampling on CPU and GPU

Adaptive Environment Sampling on CPU and GPU Ohoh, their solution, when compare to LuxCore Env. Light Visibility Cache, is a classic trade off between memory usage and quality: ELVC requires a LOT more memory/pre-processing to works well but it deliver better results ( if you use enough memory/pre-...

Re: LuxCore v2.3 proposed features

About the speed problem, I can accelerate the DLSC and EVLC (not PGI) by 2-3 times but I need to find the free time to work on it. The trick is to use Embree shadow rays instead of normal rays: I have even done a test and it was 2+ times faster but writing a complete solution is not trivial.

runs out of memory in region rendering..
About this: just set the radius by hand (i.e. use a value != from 0.0) and you will have no problems with region rendering.

Re: (Open)Subdiv and Displacement shapes

Added the support for vector displacement. Added a new paragraph to the first post with an explanation and some (sick !) example.

Re: LuxMark v4.0alpha0

By the way, I also have a version of the wallpaper scene that uses Path OpenCL + light tracing, so it wouldn't have to be a CPU-only benchmark. I was thinking to include hybrid rendering but how to you weights the GPU+CPU performance ? One doesn't eye tracing, the other does light tracing, have the...

Re: openCL issue with procedural texture and particles

I did my test in blender v2.80, may be it is a old bug of BlendLuxCore fixed in v2.80 :?:

Re: (Open)Subdiv and Displacement shapes

I think it is not used that often. It could be a nice to have feature, but haven't heard many people using/talking about it Edit. Also about the adaptivness, the only case I would find it useful are huge assets like terrains. For smaller objects, products, I don't see any need for adaptivness, coul...
