TGeoBarrier |
Top Previous Next |
Key element in defining barriers. It is a sequence of points, which can be either a line or a polygon. If the first item = last item, then it is a polygon, but the algorithm do not care.
You only need to fill in the points part, MBR (Minimum-Bounding-Rectangle) is calculated automatically.
The calculations are faster, the fewer points you use to describe a barrier.
TGeoBarrier = record points: TFloatPointArray; MBR: TFloatRect; end;
