Rules for Accept/Reject
Rejection of the pair of nodes by bounding boxes. Metric is computed to choose the best branch. Returns true if the pair of nodes should be rejected, false otherwise.
virtual bool	RejectNode (const BVH_VecNt &theCornerMin1, const BVH_VecNt &theCornerMax1, const BVH_VecNt &theCornerMin2, const BVH_VecNt &theCornerMax2, MetricType &theMetric) const =0
	Leaf element acceptance. Returns true if the pair of elements is accepted, false otherwise.
virtual bool	Accept (const int theIndex1, const int theIndex2)=0
	Leaf element acceptance. Returns true if the pair of elements is accepted, false otherwise.
Selection
Selection of the pairs of elements of two BVH trees by the rules defined in Accept/Reject methods. The method requires the BVHSets containing BVH trees to be set. Returns the number of accepted pairs of elements.
int	Select ()
	Performs selection of the elements from two BVH trees by the rules defined in Accept/Reject methods. Returns the number of accepted pairs of elements.
int	Select (const opencascade::handle< BVH_Tree< NumType, Dimension > > &theBVH1, const opencascade::handle< BVH_Tree< NumType, Dimension > > &theBVH2)
	Performs selection of the elements from two BVH trees by the rules defined in Accept/Reject methods. Returns the number of accepted pairs of elements.

Detailed Description

template<class NumType, int Dimension, class BVHSetType = void, class MetricType = NumType>
class BVH_PairTraverse< NumType, Dimension, BVHSetType, MetricType >

Abstract class implementing the parallel traverse of two binary trees. Selection of the data from the trees is performed by the rules defined in the Accept/Reject methods. See description of the required methods in the comments above.

Template Parameters

NumType	Numeric data type
Dimension	Vector dimension
BVHSetType	Type of set containing the BVH tree (required to access the elements by the index)
MetricType	Type of metric to perform more optimal tree descend
