For a while I was trying to be able to display OpenGL programs remotely, which is complicated by the use of GLX extensions. I finally figured it out, and thought that it might be useful for other students...
There is a OpenGL compatible library called Mesa, which only makes standard X calls, not GLX calls. The source is available at http://www.ssec.wisc.edu/~brianp/Mesa.html.
However, a pre-built version of the libraries for SGI can be found on the
leland systems at ~aroetter/public/lib.
Since GL is linked in dynamically, you can override the order in which the system searches for libraries to have it find the Mesa libraries first, so it will run with those (and hence display anywhere). To do this, copy the Mesa libraries into some directory, and then set up links so the system thinks they are the OpenGL libraries by typing:
% ln -s libMesaGL.so libGL.so % ln -s libMesaGLU.so libGLU.soThen you can set the environment variable
LD_LIBRARY_PATH to
be the directory where you installed the libraries:
% setenv LD_LIBRARY_PATH /some/directory/heredoes it with csh (tcsh).
After that, just set your DISPLAY and any GL program, even the pre-built demos, will run anywhere without needing to recompile it. This is slower than using GL, but it is good for times when you don't have enough time to justify getting over to sweet hall, but just want to work for a few minutes.
