[ REQ 5143]: Crayla

[celeste at obelix.asd.sgi.com]

Dear Dr. Araki:

	Thank you for your interest in Crayola.  I no longer work at
the Geometry Center, so I'll forward your mail on to them.  I believe
the the source code for Crayola is still included in the full source
release of Geomview.  I'm not sure if the NeXT, X, and SGI
distributions have been separated -- if so, Crayola is probably in the
NeXT and SGI releases.  

	Crayola is a pretty simple program.  One improvement I can
suggest is to modify it to transfer the objects in binary instead of
ascii format.  If you are dealing with hierarchical objects (for
example, lists) you might want to check out using the
(replace-geometry) command to pass only the part of the hierarchy that
has changed back through the pipe.

	Good Luck!

-Celeste

   Dear Dr. Fowler.

   I am very much interested in your "Crayola", the geomview external
   module.  Recently I made "WebPaint", a colaborative symmetrical
   drawing tool on the web, using geomview, weboogl.perl, and cgi-bin of
   httpd.  

   It is available 

   http://synap.neuro.sfc.keio.ac.jp/~aly/polygon/webpaint/webpaint.html
   .

   But my algorithm in gcl(geomview command language) is too slow
   to do.  I am very apriciate your kindness you send the source code of
   "Crayola", if possible.

   Thank you very much.
