Hello RC, I don't know about Mesa3D, but I can at least tell you how I get this to work using OpenGL. Maybe this will help you find the solution.... I have an IBM workstation on my desk. As you may know, IBM doesn't support Java3D :-( , so I can't run VisAD locally. IBM does support OpenGL though, so I've got OpenGL installed. With this, I'm able to run VisAD on a Sun workstation (which has Java3D support) and display it on the IBM (which only has OpenGL support). When I install OpenGL on the IBM, it adds "GLX" extensions to the X server. So if I do "ps -ef | grep X" on the IBM, I see something like: /usr/lpp/X11/bin/X -x abx -x dbe -x GLX -D /usr/lib/X11//rgb -T -force :0 -auth /var/dt/Aalto2-Oxcuq note the "-x" which I think stands for "extensions" followed by GLX. Others will probably be able to describe it more elegantly or correctly, but somehow the Java3D running on the Sun sends OpenGL requests to the IBM display, which are then translated into GLX calls to the X server. So if your X server isn't running GLX extensions it won't work. So the question is how to get the X server started with GLX extensions. Might be an answer on the newsgroups... I did a search for "mesa GLX" on: http://groups.google.com/advanced_group_search specifying the newsgroup as "comp.os.linux.x" and it returned a whole bunch of hits.
