de4 = ot.GetDelunayEdgeCW(op);
t.Legalize(p, op);

// Remap neighbors
// XXX: might optimize the markNeighbor by keeping track of
// what side should be assigned to what neighbor after the
// rotation. Now mark neighbor does lots of testing to find
// the right side.
t.ClearNeighbors();
ot.ClearNeighbors();

if (n2) t.MarkNeighbor(*n2);
if (n3) t.MarkNeighbor(*n3);

}示例2: Fill
void Sweep::Fill(SweepContext& tcx, Node& node)
{
Triangle* triangle = new Triangle(*node.prev->point, *node.point, *node.next->point);
// TODO: should copy the constrained_edge value from neighbor triangles
// for now constrained_edge values are copied during the legalize
triangle->MarkNeighbor(*node.prev->triangle);
triangle->MarkNeighbor(*node.triangle);
tcx.AddToMap(triangle);
// Update the advancing front
node.prev->next = node.next;
node.next->prev = node.prev;
// If it was legalized the triangle has already been mapped
if (!Legalize(tcx, *triangle)) {
tcx.MapTriangleToNodes(*triangle);
}
