- I'm hoping for joint constraints, for example, telling an elbow joint that
- it can only rotate in one plane, and only for 150 degrees in that plane,
- from a particular starting angle, and telling a shoulder joint that it is
- restricted in a similar fashion. Then, moving the wrist along a path
- would cause the arm to follow in an anatomically correct way. If the path
- pulled the wrist too far, you should be able to select whether the arm
- should resize, move from its origin, or simply try to follow the path
- without moving or resizing.
-
- Joint friction would be good, so that some joints would be 'stiffer' than
- others. ...and if we could have bulging skin for muscles when joints
- moved and stretching of the webbing between fingers, I'd be over the moon
