示例1: ExtendEdges
bool ExtendEdges(Point p)
{
// Point p is on director vector of edge e, and we extend e to include p.
List<Edge> extended = new List<Edge>();
foreach (Edge e in edges)
if (p.OnLine(e.P1, e.P2) && p != e.P1 && p != e.P2)
{
int where = p.Where(e.P1, e.P2);
if (where == 1 && p.DistanceTo(e.P1) < Epsilon)
{
e.P1 = p;
extended.Add(e);
}
if (where == 2 && p.DistanceTo(e.P2) < Epsilon)
{
e.P2 = p;
extended.Add(e);
}
}
if (extended.Count == 0) return false;
// We try to link 2 extended edges to p to form a single edge.
Point P1, P2;
for (int i = 0; i < extended.Count; i++)
if (extended[i] != null)
