Re: Boosting Monte Carlo Rendering by Ray Histogram Fusion

Looks good. If they use filtering, I seriously hope its not mine :|. You said they use MIS/RIS? Do you have the source that mentions this? Cheers :) :) Of course I didn't know what type of filtering they actually use, but it looks very promising. Today I didn't know any production render without MI...

Re: Boosting Monte Carlo Rendering by Ray Histogram Fusion

Probably you guys already see new Demo of Brigade. Unfortunately I couldn't found any description and comments on video are disabled :) There is only static geometry with instensing, Unidirectional PT with MIS/RIS and there is defensively filtering on top. I think filtering technique is close to thi...

Re: Some images from my renderer

vcm rocks ??? where are you coming from ? it is for shure the slowest approach to handle complex lighting/illumination In common cases unidirectional path tracing with external light sampling and MIS is industry standard, but there is situations where this approach has problems.(for example "flower...

Re: Some images from my renderer

Very nice renders and layered materials looks great, fingerprint layer was highest level of awesomeness :D VCM rocks, SDS paths is totally clear :) what was render time for second image(Lilacs in glass vase)? Flower scene is not a simple case for BVH with object splits, because AABBs doesn't fits we...

Re: Ray Sorting

fluid Shading part is very important because every shading event may be linked to some textures(diffuse, specular, normal, displace) and in productions renderers this number and size of textures may be very large. So processing shading events in coherently useful way really important. Your question...

Re: Colibri Renderer

Unlukily I had to give it up a few years ago, after real life demands limited my time and energy up to the point that I was no longer able to keep working on spare time projects. Too bad, as my RT was growing up nicely :( It's really hard to do such hard work for long time and it's even harder when...
