Syntax

bool FindPointsInBall
(
    const FVector3d & QueryPt,
    double QueryRadius,
    TArray< int > & ResultOut
)

Remarks

Find all points within given query distance from query point.

that in current implementation the distance must be less than the CellSize used in construction, ie at most the directly adjacent neighbours next to the cell containing QueryPt can be searched

Returns

true on success

Parameters

Parameter	Description
QueryPt	center of search sphere/ball
QueryRadius	radius of search sphere/ball. Points within this distance of QueryPt are returned.
ResultOut	indices of discovered points are stored in this list
