DynaMouse Notes June 25, 1993
---------------
It's fairly obvious what this program is about, but if you haven't looked at it yet,
here's a little description. DynaMouse gives you a brushlike pen with which to draw.
But this pen has the added features of mass and drag, allowing you to create some very
odd effects.
The algorithm that inspired this program was developed by Paul Haeberli of Silicon
Graphics, Inc. He demonstrated his program at a graphics seminar I attended at CMU.
It was such fun to play with, that I decided to make this port to Macintosh of his
routines.
In addition to creating some pretty realistic, attractive strokes, this program is
a real blast to play with. I personally can't get enough of it (but maybe I'm biased :-)
This version, 0.93b1 is being released just to let some people check it out, and
write back to me with bugs and suggestions. So if you're taking the time to play with
it, please take an extra sec to write me an email with your opinion! A full version,
allowing saving, printing, a tool palette, and all sorts of stuff will be in the works.
I'll probably release that later this year as shareware. (or pay-me-based-on-how-useful-
it-has-proved-to-be-to-your-life-or-business-Ware)
Requirements:
System 6.0.5
pseudoRequirements:
Mac IIsi or better
FPU
Details:
Well, this is a rather preliminary effort. I have not hand-assembly-coded the
drawing algorithm yet, and I haven't done a lot of thinking about my memory management.
You can keep making new windows until you get beeped at.
Once you have a new window, just draw away!! As a silly eraser I've allowed an
option to give you a white pen. Later I'll add a selection tool and a real eraser.
The calculations are very processor intensive. SO, an FPU is greatly appreciated.
But, running on my IIsi without an FPU, it's still quite usable. It REALLY drags on a
machine less than that. (Notice there are 2 versions!! One is for non-FPU machines.)
If you have a fast machine, and need to slow things down, mess with the delay loop
option. Changing that can really affect the style of your drawing.
That's all I can think of to explain...
SO! Have fun, and send me your comments!

WARNING!! This program has NOT undergone any real testing. As it doesn't mess with the
hard drive at all, there's no danger other than a system hang. (but I've never had one
with this version of DynaMouse, so I think it's rather clean)
