Version 3.0
-----------
1. PostScript output now confirm to EPSF 1.2.
2. Support for surfaces has been added using the cagd_lib module. New related
flags (see cagd_lib for more):
a. -M, draw surface/polygons mesh as well.
b. -I n, specifies number of isolines.
c. -S n, log based two of number of samples per curve. I.e. 8 specifies
256 samples.
3. SGI 4D interface to GL has been added and some shading is been used as well.
4. GIF files may now be dumped in X11 mode and in SGI GL mode.
Version 2.2
-----------
1. New -c flag has been added (ClosedObject in config file) to signal closed
object. In closed object each edge is shared by two polygon, and is
therefore drawn twice. If -c is specified the edge is drawon only once
and therefore can speed drawing by up to factor of 2. Note the polygons
are assumed to be well oriented so that the shared edges are in reverse
direction.
2. New -N and -n flags: polygon and vertices normal display if data has them
defines.
Version 2.1
-----------
1. Save gif now support the EGA/VGA modes (actually a change in the gif_lib
library).
2. Ability to dump PostScript file as well.
3. PostScript/Matrix/GIF files are now saved with incremental singal digit
file names. This means that 10 unique files can be saved simultanuously.
Version 2.0
-----------
1. A new keyword (POINTLIST) has been added. This structure is the same
as POLYLINE but only vertices points are drawn.
2. Program has been ported to Unix system and compiled under:
a. BSD4.3, using gcc
b. Iris 4d, Irix 3.2, using cc.
Program behaves the same on the unix environment, but the GIF output is
not supported there.
Version 1.2
-----------
1. EGA display device improved (slow mouse, wierd colors, etc.).
2. Warnings will stop only at file with error, instead of on every file.
Version 1.1
-----------
1. Image can be saved as a GIF file.
