Overview

In VTK 6.1 features (such as FBO) that have been disabled for OSMesa because of driver bugs in previous versions have been tested against the latest releases of Mesa. Most of the algorithms can be used with the latest Mesa release (9.2.2).

Gallium llvmpipe benchmarks

In Mesa release 9.2.0, OSMesa can be provided by the Gallium llvmpipe renderer. The llvmpipe renderer has threading (currently only for fragment shaders) and uses LLVM for JIT compilation of GLSL shaders. Using the llvmpipe renderer should give both the best feature support and performance with OSMesa.

The following chart shows the run time of VTK's Rendering ctests with OSMesa classic, Gallium llvmpipe OSMesa state-tracker, and an ATI Radeon HD 7870. The CPU on the test sytsem is a 4 core(8 thread) Intel(R) Core(TM) i7-4771 CPU @ 3.50GHz. Times were obtained by running each ctest twice consecutively discarding the first time. Tests that took less than 1 second were discarded, as were tests that failed on any one of the renderers.
