static int WhichSide
(
const TVector2 < T > & StartPt,
const TVector2 < T > & EndPt,
const TVector2 < T > & QueryPt,
T Tolerance
)
Remarks
Determine which side of the segment the query point lies on. This version is deprecated because it and the member function give opposite results. It also does not correctly handle tolerance. +1 if point is to right of line, -1 if left, and 0 if on line or within tolerance band
Parameters
| Name | Description |
|---|---|
| StartPt | first point of Segment |
| EndPt | second point of Segment |
| QueryPoint | test point |
| Tolerance | tolerance band in which we return 0 |
