示例1: A
const ViewEdge *ViewMap::getClosestViewEdge(real x, real y) const
{
// find the closest of this candidates:
real minDist = DBL_MAX;
FEdge *winner = NULL;
for (fedges_container::const_iterator fe = _FEdges.begin(), feend = _FEdges.end(); fe != feend; fe++) {
Vec2d A((*fe)->vertexA()->point2D()[0], (*fe)->vertexA()->point2D()[1]);
Vec2d B((*fe)->vertexB()->point2D()[0], (*fe)->vertexB()->point2D()[1]);
real dist = GeomUtils::distPointSegment<Vec2r>(Vec2r(x, y), A, B);
if (dist < minDist) {
minDist = dist;
winner = (*fe);
}
}
if (!winner)
return NULL;
return winner->viewedge();
