3-D Arm README
This program is the first stage of a larger project to study goal
directed animation of articulated objects. Articulated objects are
those that can move with various degrees of freedom, but are
constrained by attachment to other links within the object. Goal
directed animation consists simply of fully, or partially, specifying
a final position for (usually) the distal link of an object, and then
having the rest of the figure articulate through the required motion.
This is a surprisingly difficult problem, particularily in 3
dimensions.
A robot arm reaching for an object, after having been told its
location, is a similar problem in the 'real' world.
I have placed this program in the public domain primarily as an
example program of how to do double buffered animation from an
Intuition screen (not difficult but undocumented), and to illustrate
the effectiveness of using the Motorola Fast Floating Point routines
over those of Lattice C (the program was compiled with 3.03). An
easier interface to the FFP routines may be available on the 3.10
update. Anybody interested in these issues can look in the
programmer.doc file.
A users guide and tutorial example of using the program are also
included in the doc directory.
I am grateful to those who have made the information they acquired
programming the Amiga available to others and I make this available in
the same spirit.
