Ton shares the notes of the developers meeting in irc.freenode.net, #blendercoders.
Here are today's notes from the meeting in irc.freenode.net #blendercoders.
1) Release targets for 2.75
- The AMD patch (splitting OpenCL kernels for Cycles) is in. Kudos for Sergey Sharybin who spent quite some time on getting this to work with the rest of the Cycles code.
- There is a limited set of AMD graphics cards that will work with this, Thomas Dinges
volunteers to collect statistics the for release log on this.- Sergey still likes to add the Dependency Graph code in master. It won't affect Blender much, but it should be done before we have an official "BCon3" (test/fix period).
- Another last minute feature gets a quick review now, custom icons/previews might make it.
- Current projects and planning.
- This Wednesday it's the strict BCon3. No new stuff anymore!
2) Other projects
- Mike Erwin had some OpenGL Viewport tests to share (improved ways to draw wires).
- Kevin Ditrich is working on OpenVDB: here and here. Kevin will be in contact with Sergey (Cyles) and Lukas (caching, pipeline) to make sure things fit in future designs too.
Thanks,
-Ton-

I am stoked about OpenVDB being available in Cycles! This opens many, many possibilities. Of particular interest to me is the ability to visualize scientific data using the volume rendering capabilities of Cycles.
Hi the current projects and planning link appears to be broken at the moment. :)
Fixed, sorry about that!
wohoo, custom icons :D
I am quite curious how openCL would work with NVIDIA GPUs and xeon CPUs compared to pure CUDA on only NVIDIA GPUs.
I too am interested in multi-device OpenCL Blender benchmarks. It would be a win for notebooks with three OpenCL devices: CPU, Discreet GPU, CPU integrated GPU
Unfortunately specific combinations of OpenCL devices cannot be selected in Blender preferences and compiling the OpenCL kernel for Intel GPU is still failing (split kernel or monolithic) / not unsupported.
If anyone gets OpenCL working on a Intel 4600 GPU let me know. I'd like to see a synched render across my NVIDIA GeForce GT 730M and i7 CPU.
I dont know what the correct place to pass information about Cycles split kernel, but I tested using an AMD R7 260X and at first glance everything is fine, the only exception are the render passes (AO, Normal..... are all black) they work with the CPU rendering.
Does openCL work on ati cards that are still supported by drivers ?
Like the 5700 HD for example.
I would like to know that too, i just got my hands on two HD5970 cards, and would love it if they also were supported..
From the wiki: "...We also highly recommend a HD 7000 series GPU or above (GCN architecture), older cards are not supported and probably won't work.", http://wiki.blender.org/index.php/Dev:Ref/Release_Notes/2.75/Cycles
