Features:
* Internal multithreading supporting an arbitrary number of threads.* Fast and robust collision detection system for rigid bodies.
* Support for multiple primitive object types, both dynamic and kinematic:
-Convex Hulls
-Box
-Capsule
-Cone
-Cylinder
-Sphere
-Triangles and Triangle "soup"
-Minkowski Sum
-Wrapped Objects
* Support for many different kinds of constraints, including joint limits, velocity motors, and servomechanisms.
* CollisionRules system for defining complex interactions between entities or groups of entities.
* Per-entity collision events for easy game logic creation.
* Path-following systems for motion control and animation.
* Efficient intersection queries and events against arbitrary closed triangle meshes using the DetectorVolume.
* Thread safe interface for easy offloading.
* Continuous collision detection (linear motion or linear and angular motion), effectively solving the bullet-through-paper problem.
* Fast static triangle groups.
* Fast height field based terrains.
* Additional effective handling for large numbers of general static objects through StaticGroups.
* Support for tuning of physical properties, including friction, bounciness, and damping.
* Compound bodies formed from multiple convex sub-bodies or other compound bodies support concave and complex shapes.
* Tweakable cast-based vehicles with many dimensions of customization.
* Supports accurate buoyancy modeling.
* Extendable framework for force fields, joints, space-updated types, solver-updated types, and single entity constraints.
* Fast ray testing against the whole environment, parts of it, and individual objects.
* Effective and extensible spatial partitioning methods used in broad phase collision detection.
* Extensive math and test library toolbox.
* Fully managed code for deployment to Xbox360.
* Effective deactivation system for keeping simulations running smooth even with many objects in play.
* Extensive XML documentation for in-code information.
* Simple and easy to use.
