IMPACT Dynamics Simulator v2.1 Copyright
(c) 1993,1995 John Henckel. Impact
simulates the collision of 2-dimensional
convex polygons with graphical
animation.  The equations for collision
of irregularly shaped objects are taken
from "Dynamics" by Pestel and Thomson,
VGA, or Hercules using Borland BGI.
(Help text not readable on Hercules.)
Recommended but not required: mouse and
286 or better.

Tutorial

Experiment 1:  Kinetic doodling
  Start the program and type "a 2 3 4", this will create two tall tri-
  angles.  Position the mouse in the middle of the screen and
  click button 1.  The nearest triangle will move toward the mouse.
  Now hold down mouse buttons 1 and 2.  All the triangles are drawn
  toward the mouse (but not as quickly).  Press 't', now as the bodies
  move they leave a colorful design behind them.  Press 't' to turn off
  trace, press 'c' to clear the screen.  Press 'd' twice to delete the
  bodies.

Experiment 2:  Inclined plane
  Type "a 1 3 10 2" to make a long incline plane.  Type "a 1" to make
  a little box.  Type "g 5" to enable gravity.  Type "r 0.5" to make
  things not so bouncy.  Now using the mouse, pick up the little box
  and set it on the inclined plane.  Then watch it slide down.

The Impact program take one command line parameter which is the name
of a scenario file.  See notes below for the file format.  Some
scenario files are included in this package, for example, type
    impact exp1.dat
to load experiment 1 scenario.

Room for Improvement:
* The program defines impact as whenever the corner of one body enters
  the interior of another body, or enters a wall.  This sounds simple
  but it has many difficulties.  (a) It is possible for two bodies to
  overlap, but neither has a corner inside the other, this is very
  common with triangles because of their sharp corners. (b) It is
  possible for two bodies to each have a corner in the other, in
  this case I pick one arbitrarily. (c) It is possible for a body to
  hit a wall or another body with two of its corners, in this case I
  choose one arbitrarily.   There are certainly better ways to handle
  these cases.
* When gravity is enabled, one would like to stack objects on top of
  one another.  This doesn't work though because the acceleration
  of gravity is constant, but the acceleration of impact becomes zero
  as the bodies slow down.  Thus, they slowly mush into each other.
  To fix this, I added the 'j' parm for center adjustment factor.
  If s=1.0, then after computing the acceleration of impact, the bodies
  are separated from each other so that they no longer overlap.  This
  opens up
