Detailed Description

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

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

Template Parameters
NumTypeNumeric data type
DimensionVector dimension
BVHSetTypeType of set containing the BVH tree (required to access the elements by the index)
MetricTypeType of metric to perform more optimal tree descend

◆ Accept()

template<class NumType, int Dimension, class BVHSetType = void, class MetricType = NumType>
virtual Standard_Boolean BVH_Traverse< NumType, Dimension, BVHSetType, MetricType >::Accept ( const Standard_Integer  theIndex,
const MetricType &  theMetric 
)
pure virtual

Leaf element acceptance. Metric of the parent leaf-node is passed to avoid the check on the element and accept it unconditionally. Returns true if the element has been accepted, false otherwise.

Implemented in BOPTools_BoxSelector< Dimension >.

◆ AcceptMetric()

template<class NumType, int Dimension, class BVHSetType = void, class MetricType = NumType>
virtual Standard_Boolean BVH_Traverse< NumType, Dimension, BVHSetType, MetricType >::AcceptMetric ( const MetricType &  ) const
inlinevirtual

Basing on the given metric, checks if the whole branch may be accepted without any further checks. Returns true if the metric is accepted, false otherwise.

Reimplemented in BOPTools_BoxSelector< Dimension >.

◆ RejectNode()

template<class NumType, int Dimension, class BVHSetType = void, class MetricType = NumType>
virtual Standard_Boolean BVH_Traverse< NumType, Dimension, BVHSetType, MetricType >::RejectNode ( const BVH_VecNt theCornerMin,
const BVH_VecNt theCornerMax,
MetricType &  theMetric 
) const
pure virtual

Rejection of the node by bounding box. Metric is computed to choose the best branch. Returns true if the node should be rejected, false otherwise.

◆ Select() [1/2]

template<class NumType, int Dimension, class BVHSetType = void, class MetricType = NumType>
Standard_Integer BVH_Traverse< NumType, Dimension, BVHSetType, MetricType >::Select ( )
inline

Selection of the elements from the BVH tree by the rules defined in Accept/Reject methods. The method requires the BVHSet containing BVH tree to be set. Returns the number of accepted elements.

◆ Select() [2/2]

template<class NumType, int Dimension, class BVHSetType = void, class MetricType = NumType>
Standard_Integer BVH_Traverse< NumType, Dimension, BVHSetType, MetricType >::Select ( const opencascade::handle< BVH_Tree< NumType, Dimension >> &  theBVH)

Performs selection of the elements from the BVH tree by the rules defined in Accept/Reject methods. Returns the number of accepted elements.

◆ SetBVHSet()

template<class NumType, int Dimension, class BVHSetType = void, class MetricType = NumType>
void BVH_Traverse< NumType, Dimension, BVHSetType, MetricType >::SetBVHSet ( BVHSetType *  theBVHSet)
inline

Sets the BVH Set containing the BVH tree.
