- Just for fun last summer I wrote a 3d wire frame
- modeling program for SunView. It was fairly
- straight forward, but allowed realtime movement
- of both objects and viewer location. The problem
- I am having now is that in porting to X-Windows
- the double-buffering system I was using depended
- on direct manipulation of the SunView colormap
- and therefore wasn't portable under X.
- I discovered another approach for X-Windows that
- unfortunately slows down massively as window size
- increases. (A problem that was much less severe in
- the SunView version).
-
- If anybody out there has experience with these techniques,
- and would like to look at my code and perhaps make a suggestion,
- please let me know. If anyone out there has code which
- addresses this problem feel free to send it.
-
- Thanks,

- P.S. If anyone out there is in a generous mood,
- I would appreciate it if you could send me any
- PD ray-tracing or other 3d graphics programs
- either as source code or as encoded SPARC
- binaries.
