treeDataPoint Class Reference

Holds (reference to) pointField. Encapsulation of data needed for octree searches. Used for searching for nearest point. No bounding boxes around points. Only overlaps and calcNearest are implemented, rest makes little sense. More...

Detailed Description

Holds (reference to) pointField. Encapsulation of data needed for octree searches. Used for searching for nearest point. No bounding boxes around points. Only overlaps and calcNearest are implemented, rest makes little sense.

Optionally works on subset of points.
