[ CVSweb ] [ Homepage ] [ RSS ] [ Required by ] [ Add to tracker ]

Branch: CURRENT, Version: 2.4.2, Package name: box2d-2.4.2, Maintainer: ryoon

Box2D is a 2D physics engine for games. It features:

Collision
Continuous collision detection
Contact callbacks: begin, end, pre-solve, post-solve
Convex polygons and circles
Multiple shapes per body
One-shot contact manifolds
Dynamic tree broadphase
Efficient pair management
Fast broadphase AABB queries
Collision groups and categories

Physics
Continuous physics with time of impact solver
Persistent body-joint-contact graph
Island solution and sleep management
Contact, friction, and restitution
Stable stacking with a linear-time solver
Revolute, prismatic, distance, pulley, gear, mouse joint,
and other joint types
Joint limits, motors, and friction
Momentum decoupled position correction
Fairly accurate reaction forces/impulses
