DynamicTreeBroadPhase Class

The broad-phase is used for computing pairs and performing volume queries and ray casts. This broad-phase does not persist pairs. Instead, this reports potentially new pairs. It is up to the client to consume the new pairs and to track subsequent overlap.

Methods
 NameDescription
Public methodAddProxy Create a proxy with an initial AABB. Pairs are not reported until UpdatePairs is called.
Public methodEqualsDetermines whether the specified object is equal to the current object.
(Inherited from Object)
Protected methodFinalizeAllows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection.
(Inherited from Object)
Public methodGetFatAABB Get the AABB for a proxy.
Public methodGetHashCodeServes as the default hash function.
(Inherited from Object)
Public methodGetProxy Get user data from a proxy. Returns null if the id is invalid.
Public methodGetTypeGets the Type of the current instance.
(Inherited from Object)
Protected methodMemberwiseCloneCreates a shallow copy of the current Object.
(Inherited from Object)
Public methodMoveProxy 
Public methodQuery Query an AABB for overlapping proxies. The callback class is called for each proxy that overlaps the supplied AABB.
Public methodRayCast Ray-cast against the proxies in the tree. This relies on the callback to perform a exact ray-cast in the case were the proxy contains a shape. The callback also performs the any collision filtering. This has performance roughly equal to k * log(n), where k is the number of collisions and n is the number of proxies in the tree.
Public methodRemoveProxy Destroy a proxy. It is up to the client to remove any pairs.
Public methodSetProxy 
Public methodShiftOrigin 
Public methodTestOverlap Test overlap of fat AABBs.
Public methodToStringReturns a string that represents the current object.
(Inherited from Object)
Public methodTouchProxy 
Public methodUpdatePairs Update the pairs. This results in pair callbacks. This can only add pairs.
