| Class | |
| Foam::dynamicTreeDataPoint | |
| 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. | |
