Examples of org.jbox2d.collision.broadphase.DynamicTree

org.jbox2d.collision.broadphase.DynamicTree
A dynamic tree arranges data in a binary tree to accelerate queries such as volume queries and ray casts. Leafs are proxies with an AABB. In the tree we expand the proxy AABB by _fatAABBFactor so that the proxy AABB is bigger than the client object. This allows the client object to move by small amounts without triggering a tree update. @author daniel
