I guess I was wondering, and I think others here might share my interest, about whether we can get a copy of the binary for geomview (GL graphics) running on the sparcstation. We'd be interested to see what it looks like and what sort of performance it has. Even though we don't have any sparcstations equipped with special hardware it should still work, right? As far as incorporating GL into X-geomview, it is indeed happening. We don't yet have the OpenGL libraries so I am currently using the mggl library, which is on top of Iris-GL, to render into the camera X window created by xgeomview. To get xgeomview to have this behavior just requires compiling with the -DMGGL option. Compiling with the -DMGX11 option, of course, creates a binary that renders with plain Xlib calls. Thus, xgeomview can be set to render either with raw X or with GL! Porting should be fairly simple if you have NPGL. However, the current GL X-geomview isn't functioning perfectly yet. There are still a few things to iron out. To answer your final question, the source code of X-geomview should be available via ftp, in a day or two, in the same place you found the sun-beta binary. It is known to compile with Motif 1.1 and the X11R5 libraries. Enjoy, Daeron daeron at geom.umn.edu
