Swallowing the elephant...

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...

Re: Direct Light Sampling Cache (aka Light cache part I)

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

Re: Direct Light Sampling Cache (aka Light cache part I)

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...

Re: How do you use LuxCoreRender with 3DS Max?

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

Re: CGI tech news box

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)

Re: LuxCore v2.1 proposed features

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 ...

Re: CGI tech news box

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

Re: LuxCore v2.1 proposed features

Another, not so much feature, but request would be inline documentation of the interfaces used throughout the code - Lights, Materials, Volumes, etc. I feel we might attract a lot more developers if the code and designed choices were explained. For instance, I would love to try my hand at material d...

White balance corrector in imagepippeline
I don't mind giving a go at a c++ version of a white balancer - ive done one in the past, but correct me if I'm wrong - isn't that what tonemapping already does?

Re: LuxCore v2.1 proposed features

There has recently been a lot of work around the GGX microfacet distribution and visible normal sampling. This feature request would encompass offering the GGX distribution and also the multiple scattering ggx. Similarly there is the paper on Irridescent microfacets that was also released last year ...
