Hi Ruq,
I'm not sure why it works in 4.2 and not 4.3. I assume someone else
reading this who knows about the recent changes could comment.
The error message shows some missing open gl extensions. Are you sure
you have the latest driver installed? GL_ARB_multitexture is not
typically an issue, unless you are using the default MS driver. Also are
you sure the error messages are the same on both systems? If not, it
would be helpful to see all the messages on both systems.
Note: the AMD drivers have a bug that prevents projected tetrahedra from
working. This should be disabled on the system with the AMD card.
In general when you have issues with one volume rendering method you
could work around it by using a different one. In the "properties panel"
under the "display" group there are some controls relating to the volume
renderer. One labeled "select mapper" lets you chose different
algorithms. For instance try to change it to "Bunyk Ray Cast". In
general the "ray cast" options are slower but more dependable.

Hello,
I've installed PV 4.3 on a few PCs, all of them running Win 7 64-bit.
What I've found is that volume rendering, curiously, works on some of
them and fails on others. The error messages I got look like this:
=========================================
ERROR: In
C:\DBD\pvs-x64\paraview\src\paraview\VTK\Rendering\VolumeOpenGL\vtkOpenGLProjectedTetrahedraMapper.cxx,

GL_ARB_multitexture could not be loaded.
===============================================
This seems to only happen to the relatively old PCs (~ 4 or 5 years
old). For example one of them has graphics card of ATI Radeon HD 3450
(Microsoft Corporation WDDM 1.1), driver version 7.14.10.0018; another
laptop has Intel HD graphics, driver version 8.15.10.2559. - I'm
wondering if these are considered insufficient for volume rendering to
work with PV 4.3.
More curiously, volume rendering seems to run OK with PV 4.2 on these
machines.
Thanks,
-Ruq
