Added the support to OpenCL for PhotonGI caustic cache update.

Also the updating happens one sample later as specified: If I want cache updates at sample 8,16,24,32... I have to choose 7 as parameter. This is normal, the update is done at least after X samples, not exactly at X samples (threads continue to asynchronous render while the need of an update is rec...

They looks really good, light is everything, who need geometry ?

Cyclic cache prevents persistent cache, that has to be exposed properly in Blender. Persistent (indirect) cache should work, persistent (caustic) cache should work too but it quite pointless as the saved cache will be used only for the very first cycle ... don't talk about "Cycles" ... it confuse m...

According Nvidia: https://docs.nvidia.com/deploy/xid-errors/index.html What Is an Xid Message The Xid message is an error report from the NVIDIA driver that is printed to the operating system's kernel log or event log. Xid messages indicate that a general GPU error occurred, most often due to the dr...

Btw. I do hope by "closing pending stuff" you also mean fix for vis. cache bug and also make that env cache work on gpu

"vis. cache" = "env cache" ?

(But yes, that is the idea)

I still think it would be useful: - The cache could be re-generated periodically on CPU parallel with the GPU rendering (no performance loss :!:) It has a cost: we do hybrid rendering so if we use the CPU for cache update, we have to stop the CPU rendering (i.e. the cost). The main reason I see for...

This pretty much rendering like SPPM without radius reduction. Would it be possible to add this as well? Yes, but it would require a lot of work and be of quite little use. The current solution works transparently for all other code, reducing the radius would require some weight computation and exp...

And this with an update every 16 spp but exactly the same other caustic cache parameters: Huuuh do you mean it can be the same for Indirect cache ? so it turn as an online cache ? The same process would be trivial to do for indirect cache (i.e. it would require to change only one line of code) but ...

I added the support for periodic update of the PGI caustic cache to PATHCPU (OpenCL support will follow as usual). This pretty much rendering like SPPM without radius reduction. It is also very near to do a subset of BiDir paths. The new property to enable the updated is: path.photongi.caustic.updat...
