I have been thinking about writing a rudimentary physics engine (rigid body perhaps). I could make it public if people are interested.
Trouble is, I dont have any experiences with commercial API's. I'm interested in seeing some API documentation.
Most importantly, I would like to ask what kind of an interface would you require. There are pretty complex issues, such as how to deal with the objects (mathematical models or mesh models)
Can some people here share their experiences?
