xwave is a simple demo program that plots a perspective projection
of a 3-d mesh surface and then "waves" it in real time.  We have
tested it under Ultrix 4.0, HP-UX 7.0, and SunOS 4.0.3.  It works
on both X11R4 and X11R3 servers.

The program works best on a risc workstation; if you have something
slower, try making the MAXROWS and MAXCOLS constants smaller numbers.
15 by 15 works pretty well on slower machines.

While the program is running, you can use the mouse to move the
plot around, and the left and right mouse buttons to zoom it in and
out.

Users with color displays can specify the -3d option.  Be sure to
have your 3-d glasses ready (if you don't have any, you can make
them out of red and blue cellophane :-).  The effect is pretty
interesting.

There are a few more options; these are all described in the man
page.  Inquiries, bug reports, etc. should be directed to
paulr@umbc3.umbc.edu.

Xwave may be freely copied and redistributed in any form, providing
the authors' names stay with the source code.  Let us know if you
like it, improve it, etc.
