Abstract class for computation of the min distance between some Object and elements of BVH tree. To use this class it is required to define two methods: More...
#include <BVH_Distance.hxx>
Public Member Functions | |
Constructor | |
BVH_Distance () | |
Constructor. More... | |
Setting object for distance computation | |
void | SetObject (const ObjectType &theObject) |
Sets the object to which the distance is required. More... | |
Compute the distance | |
NumType | ComputeDistance () |
Computes the distance between object and BVH tree. More... | |
Accessing the results | |
Standard_Boolean | IsDone () const |
Returns IsDone flag. More... | |
NumType | Distance () const |
Returns the computed distance. More... | |
Definition of the rules for tree descend | |
virtual Standard_Boolean | IsMetricBetter (const NumType &theLeft, const NumType &theRight) const override |
Compares the two metrics and chooses the best one. More... | |
virtual Standard_Boolean | RejectMetric (const NumType &theMetric) const override |
Rejects the branch by the metric. More... | |
virtual Standard_Boolean | Stop () const override |
Returns the flag controlling the tree descend. More... | |
Public Member Functions inherited from BVH_Traverse< NumType, Dimension, BVHSetType, NumType > | |
BVH_Traverse () | |
Constructor. More... | |
void | SetBVHSet (BVHSetType *theBVHSet) |
Sets the BVH Set containing the BVH tree. More... | |
virtual Standard_Boolean | AcceptMetric (const NumType &) const |
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. More... | |
virtual Standard_Boolean | RejectNode (const BVH_VecNt &theCornerMin, const BVH_VecNt &theCornerMax, NumType &theMetric) const=0 |
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. More... | |
virtual Standard_Boolean | Accept (const Standard_Integer theIndex, const NumType &theMetric)=0 |
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. More... | |
Standard_Integer | Select () |
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. More... | |
Standard_Integer | 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. More... | |
Metrics comparison for choosing the best branch | |
Rejection of the node by metric | |
Condition to stop the descend |
