[Paraview] OpenGL2 and ParaView 4.3.1 ...

[Stock, Mark]

Niklas,

The CMake command that builds a workable Paraview 4.3.1 with OpenGL2 backend for me is:

cmake28 -DVTK_RENDERING_BACKEND=OpenGL2 -DQT_QMAKE_EXECUTABLE=/opt/qt/4.8.5/bin/qmake -DCMAKE_INSTALL_PREFIX=/opt/ParaView/ParaView-v4.3.1-OpenGL2 -DCMAKE_BUILD_TYPE=Release -DPARAVIEW_BUILD_PLUGIN_SciberQuestToolKit=OFF -DPARAVIEW_BUILD_PLUGIN_PointSprite=OFF -DPARAVIEW_BUILD_PLUGIN_EyeDomeLighting=OFF -DPARAVIEW_BUILD_PLUGIN_MobileRemoteControl=OFF -DPARAVIEW_BUILD_PLUGIN_SurfaceLIC=OFF -DPARAVIEW_BUILD_PLUGIN_UncertaintyRendering=OFF -DPARAVIEW_BUILD_PLUGIN_RGBZView=OFF

(cmake28 because I'm on RHEL 6.5)

I have not tried volume rendering yet, and it still seems to crash on some filters, but triangle mesh rendering is at least 20x faster. Can you turn off HAVS and just use the projected tetra method for volume viz?

Mark

Hi,

I do get ParaView with OpenGL2 compiled and running, even with some of
the plugins. But it crashes quite quickly with the following error message:
     vtkSIProxy (0x5953890): Failed to create vtkHAVSVolumeMapper.
Aborting for debugging purposes.

Has anyone gotten ParaView really working with OpenGL2? The current
volume rendering is beyond painfully slow ...

Thanks,
Niklas
