Embree accelerated BVH building for OpenCL too

is embree work on AMD and Nvidia GPUs now :?: :shock:
PATHOCL+METROPOLIS output difference with PATHOCL+RANDOM/SOBOL


Are you speaking about sobol tendencing to draws checkerboard patterns on render ?

No (or not exactly): the GPU structures to accelerate ray/triangle intersection are built on the CPU and than transferred to the GPU before to start the rendering. The structures are now built using Embree (i.e. better result and in a shorter pre-processing time).

No, it is just about the average image luminance, compare the images shown at https://github.com/LuxCoreRender/LuxCore/issues/11 and you can see a difference when using PATHOCL+METROPOLIS Vs PATHOCL+RANDOM/SOBOL.

There have been 3779 commit since the LuxRender v1.6: https://github.com/LuxCoreRender/LuxCor ... ender_v1.6

We should release a bit more often :roll:

Yes. Like I said here:
One other thought: Maybe it would be good to publish releases more often, but keep the development non-accessible in between (at least for users who don't compile).
What I mean is that we don't publish daily builds etc. because it creates a lot of forum posts where people ask why their exporter/binary is broken because of a mismatch and other problems.
And every two months or so we would package a new release with a few new features.
My hope is that this would decrease the support we have to do in the forum.

The optimum would be to have 4 releases each year. It may be hard but 3 is the bare minimum. LuxRender had an average of about 1 release every 1.5 years.

My next big target is https://aws.amazon.com/batch/?nc1=h_ls (with support for network rendering of single images and animation frames).

It is a typo: I wrote "warp" instead of "wrap". It is this kind of "wrapping": https://open.gl/textures
