Hi,
I ran into the "empty not supported extensions list", with linux/ATI/Mesa.
By reading, I found that the problem is not due to extensions, but due
to:
if(strstr(gl_vendor,"ATI")!=0)
{
this->LoadExtensionsSucceeded=0;
return;
}
and
if(strstr(gl_version,"Mesa")!=0)
{
this->LoadExtensionsSucceeded=0;
return;
}
(Code from
ParaView3/VTK/VolumeRendering/vtkOpenGLGPUVolumeRayCastMapper.cxx)
My feeling is that GPU raycast mapping is impossible with ATI card.
My question is: Am I wrong? If there is any, what should I do to enable GPU
rendering on ATI?
Thanks a lot!
Jerome
(ps: I tried with an NVidia quadro and... wow! Thanks!)
