Sorry, no progress so far with the LDA2002 project.
But I had a new idea today, mostly useful for making libraries of minifig
animation.
The basic idea is to make it viewable in any LDraw viewer and portable for
different LDraw animation systems or utilities. Sorry not POV, I'm afraid -
but who knows...!
The idea is based on using the STEP metacommand in a little different way.
The colour and the part numbers could of course be ignored or overridden by
the program calling the behaviour file.
In my system, most animation related .dat files are named matching "@*.dat",
and I would suggest that minifig animation behaviour files hould be named
"@mf*.dat".
I don't think this system is useful in all objects, for example vehicles
have different sizes and distances between their wheels. Yes, even different
number of wheels. Hopefully I'm wrong and this can be solved, too. Maybe in
a distant future, a model file can carry the information that enables any
animation program to make basic animations.
But let's take one step at the time.

| (...) You should try and merge/append this with the connection database, e.g. model behavior vs. part behavior. No sense coming up with two different ways of doing basically the same thing. (20 years ago, 20-Jan-05, to lugnet.cad)
