Remarks
Find nearest point within radius. Note: Not thread-safe to update, remove or insert points during this query. the found pair (Value,DistanceSqFunc(Value)), or (InvalidValue,MaxDouble) if not found
Parameters
| Name | Description |
|---|---|
| QueryPoint | the center of the query sphere |
| Radius | the radius of the query sphere |
| DistanceSqFunc | Function you provide which measures the squared distance between QueryPoint and a Value |
| IgnoreFunc | optional Function you may provide which will result in a Value being ignored if IgnoreFunc(Value) returns true |
