The NovodeX Physics SDK unites rigid body dynamics simulation and collision detection in a single easy-to-use package. The Physics SDK builds only on the Foundation SDK, a library of mathematics and utility functionality. It has no other dependencies. This document familiarizes the reader with both SDKs. The rigid body dynamics component enables you to simulate objects with a high degree of realism. It makes use of physics concepts such as reference frames, position, velocity, acceleration, momentum, forces, rotational motion, energy, friction, impulse, collisions, constraints, and so on in order to give you a construction kit with which you can build many types of mechanical devices. While this documentation will cover the features and usage of the SDK, because of the academically challenging nature of the subject matter, it is assumed that you have mastered the material covered in the mechanics part of an introductory physics course. If not, it is recommended that you get hold of a good book and familiarize yourself with the concepts listed above before continuing.
