Bullet Physics Engine

After a few months banging my head against Bullet (http://bulletphysics.org), which apparently could make my life a lot easier:
Bullet is a Collision Detection and Rigid Body Dynamics Library. The Library is Open Source and free for commercial use, under the ZLib license. This means you can use it in commercial games, even on next-generation consoles like Sony Playstation 3.
I have chosen to abandon this strategy for the time being given the following conclusions:
  • Physics engines in general try to be as general as possible, becoming extremely complex when it comes to learn how they work.
  • Physics engines are normally game-oriented, and although I haven't been able to prove it yet, their lack of precision might become an important issue when it comes to solve engineering problems.
  • There is no way around in deeply understanding the numerical methods they employ.
Nonetheless, this is the amount of research done so far:

With this in mind, I think the next step will be to focus on achieving the knowledge to tackle my own physics engine!
