the method I mentioned also relies heavily on c++ templates Sounds like it would be rather complicated to translate to OpenCL? I haven't honestly looked atthe opencl side of the engine. the way this is accomplished on the CPU side is thru templating which cl doesn't have. the CPU side abstracts out...

polarization and diffraction isn't just good for rendering a CD tho. its also useful for the rendering of rainbows ( Jensen did a paper several years ago about extending mie scattering to accurately render double rainbows), but also for glowing solid objects(wilkie), birifringence in crystals, fluor...

octane render recently announced their 2018.1 release features (including something they call "vectron" and "spectron") while spectron is really exciting to me (it includes support four rendering fluorescence and polarization), vectron is merely an implementation of something I s...

matt pharr, of pbrt fame, recently did a series of blog posts on getting a scene from moana to run and render over pbrt3. while this isn't as much cgi news, it would be neat to convert a production ready scene to luxcore and see if we can render it. the scene is somewhere between 50-70gb when loaded...

interesting - the many light problem has been a hot topic the last couple of years - with a lot of people tackling it - it's always nice to pick your brain and get the reasons behind your decisions and directions you are taking

another thought that is somewhat related (I think) tungsten and pbrt v3 both use a spatial light cache, albeit not exactly what you're doing. tungsten is using solid angle sampling iirc which is supposed to help calculate things faster. I believe pbrt v3 even has solid angle sampling of triangles in...

there isn't currently an exporter available for 3ds max - we need a community member to take the lead and develop one if we are going to have one

A Practical Extension to Microfacet Theory for the Modeling of Varying Iridescence I actually mentioned this in the features wishlist thread along with the improvements to glossy surfaces and the GGX microfacet distribution. the implementation is even included on the project website (for mitsuba)

Unbiased Photon Gathering for Light Transport Simulation Beyond Points and Beams: Higher-Dimensional Photon Samples for Volumetric Light Transport Example Implementation If it's not too late to enter a suggestion, these papers both seem very promising. They build on the VCM/UPBP techniques and can ...

out of core geometry and textures in luxcore would be a huge feature.
