class OrientedBoxTreeTool

Detailed Description

Traversal statistics structure.

Structure to accumulate statistics on traversal performance. Passed optionally to query functions, this structure contains the count of nodes visited at each level in a tree, and the count of traversals that ended at each level. One TrvStats structure can be used with multiple OBB trees or multiple queries, or used on only a single tree or a single query.

Note that these traversal statistics are not related to the stats() query below, which calculates static information about a tree. These statistics relate to a tree's dynamic behavior on particular operations.
