Dear Damien,
I'm not 100% sure what you are saying for a lot of this post but I do have to
say that writing an animation scripting language, even utilising what else is
around, is a very difficult task.
As a simple example of how hard this problem is, lets say the only animation
allowed would be from sub-models with a defined connection to other sub-models
(perhaps through a meta-command). With one connection, the problem is
straightfoward, with two, a little more difficult, if we want five connections
though, we already have a difficult computational problem, even without a
physics engine. Once we throw in a physics engine it becomes even more
complicated.
I'm not saying it can't be done. Just that it is difficult. It obviously could
be written given enough time and energy. For me though, I do not have the free
time, nor the inclination to embark on such a large project. If you believe you
can do it on your own then go ahead and if it works effectively I'm sure people
will use it. I would be happy to volunteer mathematical 'expertise' to such a
project were it required.
