Hi All,<br>
<br>
VTK 6.1 will take full advantage of OpenGL features in OSMesa. In the past this hadn't been the case, a number of key algorithms or classes that algorithms depended on were explicitly disabled when OSMesa was detected. I've been investigating use of the new 9.2.2 Mesa release in which OSMesa can take advantage of the VMWare's Gallium llvmpipe back-end. The advantages of this back-end over the classic OSMesa back-end are better OpenGL extension support, threading, and use of LLVM/clang for shader compilation. The llvmpipe backend is quite a bit faster on shader heavy algorithms and supports Surface LIC while the classic back-end does not. In the recent Mesa 9.2.2 release it finally works flawlessly with pvbatch.<br>
<br>
The Mesa 9.2.2 release configured with the Gallium llvmpipe OSMesa state tracker should be the recommended Mesa release for off-screen rendering in VTK and ParaView and I've updated the wiki with build instructions and some rendering benchmarks.<br>

I've left a link to the old page, if there are no objections I'd like to remove it.<br>
<br>
I've set up ParaView and VTK dashboards for the new 9.2.2 Mesa release<br>

If you guys see anything wrong with it , please let me know.<br>
