Parameters
| Name | Remarks |
|---|---|
| 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 |
