Re: Cycle X (and OpenCL)

There is the whole SYCL thing that tries to somewhat standardize things accross vendors. https://sycl.tech/ The Intel OneAPI is apparently one implementation of that and there is https://github.com/illuhad/hipSYCL that tries to build a multi-backend implementation for that, but I don't know how matu...

Re: LuxCore Windows Compile Time

On windows, for development I would disable the LTCG option in the build.

It takes a long time because it goes over all build artifacts to do linking-time optimization

It is really short without it

Re: Limit CPU threads for compilation (Windows)

When I am on Windows I always disable the LTCG flag (and also the Gy too, I think).
The issue is the linking-time optimization.

Re: BlendLuxCore: Save image while render is paused

You have to rename the images or move them somewhere else if you want to prevent them from being overwritten. I guess you could probably do something like: import os from datetime import datetime os.rename('a.exr', '{}.exr'.format(datetime.now().strftime('%Y-%m-%d-%H-%M-%S') Just change a.exr to th...

Re: Blue noise dithered Sobol

Just to give an update, I haven't really been able to create something that: Has blue-noise characteristics in screen space Doesn't have a heavy correlation between dimensions Doesn't need to generate an absurd amount of samples The version using Owen scrambled Sobol samples works ok for the first 2...

Re: Activation problem with V 2.3

Mint is based on Ubuntu.

The 18 release is still based on Ubuntu 16.04, if I'm not mistaken.

Re: Blue noise dithered Sobol

BTW keep in mind that I posted here an evolution of that method, this is the link: https://hal.archives-ouvertes.fr/hal-02158423/file/blueNoiseTemporal2019_slides.pdf This is only valid for animation rendering. The counterpart for still rendering is the one I mentioned in the first post, using Owen...

Re: Blue noise dithered Sobol

Thanks for the test. As far as I understand, the method implemented in Cycles is described here: https://www.arnoldrenderer.com/research/dither_abstract.pdf This method degrades into white noise as the rendering goes on, so I assume that by 200 samples there would be not that much difference between...
