typedef std :: map

As a programmer, but also for the love of the game, and more leisure to write a program associated with the game. Suddenly a thought one day their ancestors have said, to do a benefit to the people. Decided to write some reusable, do not be cited to give something scbeasy (as a research staff, always referenced there is a knot). The idea to write a physics scbeasy engine was born. What? Why is the physics engine. As a graphics researcher scbeasy (pseudo), write to the graphics engine is already not interested. In order to enhance their ability to determine scbeasy in practice, learning, writing a physics engine. One time, capacity, are also limited, can not write what Big World, called the Small World. In my view, this program is the cannon fodder of the material, but the game can do for the cause of the rise of my heavenly when the cannon fodder is not a bad thing. I hope I can be as humble as a little of the future of the majority of ACG programmers and enthusiasts have a little bit of help.
For game development, probably somewhat covered are aware of several existing, or that several of the more popular physics engine: Havok, Physx, Bullet, ODE, Newton. . . (In fact, I originally wanted to call this Newton's physics engine, because I found that I could achieve nothing more than part of Newton's classical mechanics, but unfortunately already have.) Most of these engines are open source, scbeasy and many are free. I used it ODE, Havok seen some related articles. Thought to want to want to write a not complicated, portability, based on C ++ language, to achieve scbeasy the following scbeasy functions physics engine.
