After reading Collada Physics specifications, I've understood that force_fields can be used to represent motors, since motor apply a force in some way. (Correct me if I'm wrong)
Specification also states that currently there is not predefined way to describe a technique.
So, my question is (if above is all true): "Has anyone defined their custom force fields? And if so, could you share your xml approach?"
I'm particularly interested in such motors as:
- Attractor motors (provide gravitational attraction between two objects)
Geared motors (simplified automobile engines)
Servo motors (achieve a desired angle or velocity)
Thruster motors (provide a constant force on an object)
Velocity motors (use force to achieve desired velocity)
I'd imagine that this has already been addressed by various exporters and importers for 3dsmax, ageia, etc., as I have seen videos running various physical simulations that would require some form of force_fields. For example, some videos were showing car simulation, which would require creating some motor to drive and steer the car.
Thanks in advance.
