What are the difference ?The solution for light cache I have in mind is a bit less sophisticate than Corona one but it is less sophisticate to make possible a GPU implementation. So the outcome should be in favor of LuxCore. Especially if you have a Titan V
Corona's UHDCache is really a good solution with on-line training, small memory footprint, etc. but if you run 5-10 times faster in term of brute force, you have a very good head start
No because of GPUs. It will be built during a pre-processing stage so it can be transferred to the GPUs.Sharlybg wrote: ↑Mon Apr 16, 2018 10:07 amWhat are the difference ?The solution for light cache I have in mind is a bit less sophisticate than Corona one but it is less sophisticate to make possible a GPU implementation.

Luxcore will not be online ?
excuse me if i'm insisting like this but i've more questionNo because of GPUs. It will be built during a pre-processing stage so it can be transferred to the GPUs.
On-line training is better because the quality of the light cache improve over the rendering time. The quality of light cache built during a pre-processing phase is constant over the rendering time. CPU Vs. CPU, a light cache with on-line training is better than one without.Sharlybg wrote: ↑Mon Apr 16, 2018 4:42 pmexcuse me if i'm insisting like this but i've more questionNo because of GPUs.

If we take CPU only as reference (no GPU acceleration).
1) Do we lose a lot of performance compared to online method ?
Oh this is what i fear. It seem to be the most efficient way. If i've to choose i go for online. The current state of luxcore bidir engine is already good even on mid range i7. All my interior and caustics renders goes througt bidir cpu. I prefere to have online light cache on a Threadripper (3x faster than my i7 6700k). i think it is more efficient to have Bidir + online LC for indirect and caustic and GPU + path tracer + denoise for simple case and exterior.On-line training is better because the quality of the light cache improve over the rendering time.
