Hi,
I can provide some more information about this problem which I reported to
Jupiter.
Our custom build of Mesa 9.1 (built following instructions from the TurboVNC
webpage) does support some (most?) 3D applications.
The one we are struggling with is UCSF Chimera: http://www.cgl.ucsf.edu/chimera/
There is some information on Graphics/Mesa issues here:
http://www.cgl.ucsf.edu/chimera/data/downloads/1.7/linux.html
When it starts up, we are getting a message saying "Outline highlight not
supported by hardware" and "Possible display misconfiguration", which occurs
when Chimera is trying to call this code:
#ifndef CHIMERA_OSMESA
if (togl == NULL)
return;
Togl_MakeCurrent(togl);
#else
OSMesaMakeCurrent(static_cast<OSMesaContext>(state_->context()),
framebuffer, GL_UNSIGNED_BYTE, myWidth, myHeight);
#endif /* CHIMERA_OSMESA */
in
http://plato.cgl.ucsf.edu/trac/chimera/browser/trunk/libs/_chimera/LensViewer.cpp
Building UCSF Chimera from source is apparently very difficult / impossible due
to licensing issues and lack of documentation:
http://www.cgl.ucsf.edu/chimera/sourcecode.html
So we are using a binary distribution, which tries to bundle all of its
dependencies within its package wherever possible, rather than relying on
external dependencies. The binary distribution of UCSF Chimera provides
graphics-related shared libraries including libftgl.so.2.1.3, libgfxinfo.so,
libGLU.so.1.3.070601, libGLw.so.1.0.0, plus the Python packages PyOpenGL and
ToGL.
Cheers,
James

Wave(TM): Endpoint Security, Q1 2013 and "remains a good choice" in the
endpoint security space. For insight on selecting the right partner to
