The Iray Light Transport Simulation and Rendering System: https://arxiv.org/pdf/1705.01263.pdf

An interesting reading with few inside information (they did dispersion, as LuxCore does, before me, damn ! :lol: ).

Bidirectional Engine under GPU boost. They also compare Luxrender with they bidir GPU engine.

Yes i clearly remind this situation about bidir and had it in mind when posting this paper here. Just do it to never forget about all interesting thing i found for this topics.

It is clear it isn't the way to go by now. If you want to know my main wish is currently this one :
- a cache to accelerate renderings and use efficiently any number of light sources in a scene.

Going to implement the first one now, the second is a bit more complex and may be something more appropriate for the next version.
Really hope when this happen it will Rock. But step by step don't want to be to exited. :lol:

Irawan shading model, quite interesting, it may be worth integrating in LuxCore as a texture: https://github.com/Thunderloom/ThunderLoom

Importance Sampling of Many Lights With Adaptive Tree Splitting: https://sites.google.com/site/ckulla/home/many-lights

Interesting but it may be redundant once we have a light cache.
