Overview 2012

It’s been a while since I last wrote to my blog, so here’s an overview of what has happened during 2012.
Blender 3D
During 2012 I’ve gradually stepped down of many of my Blender 3D development and maintenance tasks. I used to run the build-bots for MingW64 and MSVC, but they were moved to the Blender Institute, so I could fully use my own machine again. Other work is currently more priority, so I thought it wise to move to the background, and not hold back important development, just because I didn’t have enough time to invest next to family, day job … Continue Reading

Blender 2.5 – r25133 – SSE optimisation for Renderer, Part II

So, I thought I had done nice optimised builds, but it turned out that SIMD optimisation was missing. I’ve now committed some SCons support for this though. The optimisations can now be turned on by building with scons using WITH_BF_RAYOPTIMIZATION=True.

I have re-uploaded 32bit and 64bit builds to graphicall.org that now have SSE optimisation for the renderer enabled.  You should now be able to successfully use SIMD QBVH and SIMD SVBVH, which would print that SSE was disabled during compile time when using the previous builds I posted.

To use any of the optimisations, check the Performance panel in render settings. The … Continue Reading

Blender 2.5 – r25127 – SSE optimisation for Renderer

I have uploaded 32bit and 64bit builds to graphicall.org that have SSE optimisation for the renderer enabled. This is not a default setting, but I thought it’d be good to get some testing results out of it – whether it causes render artifacts or not, and such.

To use any of the optimisations, check the Performance panel in render settings. The Auto setting tries to select the best optimisation strategy, but you can choose any of the other ones too. Octree is what we know from the previous Blender series, all the new names are from the GSoC work done … Continue Reading
