With a recent JDK and 1.2Ghz Athlon I get ~26 fps with appletviewer on Linux. 
 Same JDK version on win2000 933Mhz PIII, gives ~73 fps (with the obvious 
change to the number of repaint()s/sec).

Anything involving java and the GUI is extra painful on Linux, where Java's 
display semantics don't sit well with X window's architecture.

This reminds me, I had a much more fully functional java caverot (zooms, 
rotations, read standard .3d etc) which I almost had finished 18 months or so 
ago - before I lost interest.  I might look it out and post it, when I have a 
moment.
