Advice on collision detection APIs

Question

I have been trying out bullet SDK for collision detection in games in my spare time but I have found it hard to learn since there are scarce examples to learn from on the Internet.

Question:
What alternatives do I have for collision detection in terms of:

• Ease of use
• Support
• Availability of tutorials online
• And, preferably, an open-source license

Thanks.

Answer 1

I found myself deciding between Chipmunk and Box2D for iPhone projects. I opted for Chipmunk and have no complaints. I'd never used a physics engine before, so it was easy enough, but I'm not experienced enough to comment on their relative strengths and weaknesses.

• Box2D is written in C++, sports a zlib license, and has a dedicated forum.
• Chipmunk is all C, MIT licensed, and hosts a pretty active forum of its own.

Each has several language bindings / interfaces (Box2d | Chipmunk).
