bool CollectCurvesNearRay

TArray < FNearest > & ResultsOut,
TFunction < bool &, const FVector3d &)> PointWithinToleranceTest
) const
Remarks
Like FindNearestCurveToRay, but gives all elements within tolerance, rather than just the closest.
PointWithinToleranceTest is called in parallel and hence must be thread-safe/re-entrant! true if at least one result was added (ie, passed PointWithinToleranceTest).
Parameters
| Name | Description |
|---|---|
| Ray | query ray |
| ResultsOut | populated with information about successful nearest point results. Not cleared in advance. |
| PointWithinToleranceTest | should return true if two 3D points are "close enough" to be considered a hit |
