Farseer Physics Engine - 基于Box2D的物理引擎

Farseer物理引擎是一個具有真實的物理反應的碰撞檢測系統。這意味著你可以利用這個引擎和相關工具容易創建一個游戲或機器人仿真。從一個簡單游戲到復雜的機器人仿真，都可以利用Farseer物理引擎實現。
Farseer物理引擎是基于Box2D的，這意味著擁有一些與Box2D共有的功能。其它特性如下：

• Continuous collision detection (with time of impact solver)
• Contact callbacks: begin, end, pre-solve, post-solve
• Convex and concave polyons and circles.
• Multiple shapes per body
• Dynamic tree and quad tree broadphase
• Fast broadphase AABB queries and raycasts
• Collision groups and categories
• Sleep management
• Friction and restitution
• Stable stacking with a linear-time solver
• Revolute, prismatic, distance, pulley, gear, mouse joint, and other joint types
• Joint limits and joint motors
• Controllers (gravity, force generators)
• Tools to decompose concave polygons, find convex hulls and boolean operations
• Factories to simplify the creation of bodies
