void RangeQuery
(
const FAxisAlignedBox3d & Bounds,
TFunctionRef < bool> PredicateFunc,
TArray < int > & PointIDsOut,
TArray < const FSparsePointOctreeCell * > * TempBuffer
) const
Remarks
Collect PointIDs from all the cells with bounding boxes that intersect Bounds, where PredicateFunc passes
Parameters
| Name | Description |
|---|---|
| Bounds | query box |
| PredicateFunc | return true if point should be included (ie this is a filter) |
| PointIDsOut | collected PointIDs are stored here |
| TempBuffer | optional temporary buffer to store a queue of cells (to avoid memory allocations) |
