FSparseDynamicPointOctree3::ParallelRangeQuery

Collect PointIDs from all the cells with bounding boxes that intersect Bounds, where PredicateFunc passes Query is parallelized across Root cells.

Include	#include "Spatial/SparseDynamicPointOctree3.h"

Syntax

void ParallelRangeQuery
(
    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 Query is parallelized across Root cells. So if there is only one Root cell, it's actually slower than RangeQuery() due to internal temp buffers.

Parameters

Parameter	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)
