Detailed Description
template<class NumType, int Dimension, class ObjectType, class BVHSetType>
class BVH_Distance< NumType, Dimension, ObjectType, BVHSetType >
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:
- RejectNode to compute distance from the object to bounding box
- Accept to compute distance from the object to the element of tree
- Template Parameters
-
NumType Numeric data type Dimension Vector dimension ObjectType Type of the object to which the distance is required BVHSetType Type of the set on which BVH is built
