Eigen::KdBVH
template<typename _Scalar, int _Dim, typename _Object>
class Eigen::KdBVH< _Scalar, _Dim, _Object >
A simple bounding volume hierarchy based on AlignedBox.
- Parameters
-
_Scalar |
The underlying scalar type of the bounding boxes |
_Dim |
The dimension of the space in which the hierarchy lives |
_Object |
The object type that lives in the hierarchy. It must have value semantics. Either bounding_box(_Object) must be defined and return an AlignedBox<_Scalar, _Dim> or bounding boxes must be provided to the tree initializer. |
This class provides a simple (as opposed to optimized) implementation of a bounding volume hierarchy analogous to a Kd-tree. Given a sequence of objects, it computes their bounding boxes, constructs a Kd-tree of their centers and builds a BVH with the structure of that Kd-tree. When the elements of the tree are too expensive to be copied around, it is useful for _Object to be a pointer.
