Summary

Dynamic aabb tree implementation as a prunning structure

Fields

Member

Description

static NullNode

A dynamic tree arranges data in a binary tree to accelerate queries such as volume queries and ray casts. Leafs are proxies with an BoundingBox. In the tree we expand the proxy BoundingBox by Settings.b2_fatAABBFactor so that the proxy BoundingBox is bigger than the client object. This allows the client object to move by small amounts without triggering a tree update. Nodes are pooled and relocatable, so we use node indices rather than pointers.

Methods

Member	Description
AddProxy(ref BoundingBox, Object, uint, bool)	Create a proxy. Provide a tight fitting BoundingBox and a userData pointer.
RemoveProxy(int)	Destroy a proxy. This asserts if the id is invalid.
MoveProxy(int, ref BoundingBox, Vector3)	Move a proxy with a swepted BoundingBox. If the proxy has moved outside of its fattened BoundingBox, then the proxy is removed from the tree and re-inserted. Otherwise the function returns immediately.
GetUserData<T>(int)
GetRoot()
GetLeafCount()
GetLeafCount(int)
GetNodeLeaves(int, List<int>)
GetAabb(int)
GetChildren(int, ref int, ref int)
GetFatAABB(int, ref BoundingBox)	Get the fat BoundingBox for a proxy.
Query(Func<int, bool>, ref BoundingBox)
CountLeaves(int)
GetHeight()
Balance(int)
