示例1: DoesLineCrossBoundery
private bool DoesLineCrossBoundery(IntPoint startPoint, IntPoint endPoint)
{
for (int bounderyIndex = 0; bounderyIndex < bounderyPolygons.Count; bounderyIndex++)
{
Polygon boundryPolygon = bounderyPolygons[bounderyIndex];
if (boundryPolygon.Count < 1)
{
continue;
}
IntPoint lastPosition = boundryPolygon[boundryPolygon.Count - 1];
for (int pointIndex = 0; pointIndex < boundryPolygon.Count; pointIndex++)
{
IntPoint currentPosition = boundryPolygon[pointIndex];
int startSide = startPoint.GetLineSide(lastPosition, currentPosition);
