Graphics demos:
---------------
(To demonstrate vt100 capabilities use vttest by Per Lindberg.  It's not
 included here to save space and since just about everyone has a copy of
 it stashed away somewhere.)

Bounds queries cterm for the current graphics bounds.
The information cterm returns is then printed on stdout.

Bounce, clock, grav and stringart are MGR demo programs which have
been adapted to work with cterm's home-brew graphics sequences.
Nothing fancy or particularly fast but the capabilities suit
my needs even if it's only used to view gnuplot output.
And sometimes it's fun to just sit and watch them run.

Spf3 is the latest version of "Spline Fun" adapted for cterm.

Mandel is a unix-ified version of MandelHandle, a program which
appeared in _Computing Now!_, a local magazine edited by Steve Rimmer.
Mandel should produce a view of the familiar Mandelbrot "Turtle."

Run "make" and then try each one.
Remember to have "interlace" on (setup B, block 3, right-most bit).
Use Ctrl-C (or whatever you use for <interrupt> or <break>) to exit.
To clear the graphics screen ...
	% echo "^[@J^[@M"		(where ^[ is ESC).


The MGR demo source files still have the Bellcore copyright since they
are pretty much intact with respect to the originals.  Spf3 is
copyrighted by Jef Poskanzer and Mandel still has Steve Rimmer's
copyright since the most of their original code is still intact.  In all
the demo programs the only changes I made were to the output generation
parts and to some of the operating parameters.

Spheres is a filtered-for-cterm version of the balls demo
included in Mark VandeWettering's MTV ray trace package.
Run "make picture" to unpack and view the scene.
