示例1: ProjectOnSegment
public static Point ProjectOnSegment(this Point pnt, Point segStart, Point segEnd)
{
Contract.Ensures((pnt - Contract.Result<Point>()).LengthSquared <= (pnt - segStart).LengthSquared);
Contract.Ensures((pnt - Contract.Result<Point>()).LengthSquared <= (pnt - segEnd).LengthSquared);
var v = segEnd - segStart;
if (v.LengthSquared <= double.Epsilon) // segment is of length almost zero. Therefore any point is valid.
return segStart;
var u = pnt - segStart;
var t = (u * v) / (v * v);
if (t < 0) // to the "left" of segStart
return segStart;
else if (t > 1) // to the "right" of segEnd
return segEnd;
else // between segStart and segEnd
{
// the point segStart + t * v is still considered a candidate because of a numerical error that can occur
// in the computation of "t". So we still need to choose the point with minimal distance to "pnt".
// We do it to ensure the contract above is correct - that is, we find the closest point to "pnt" on the segment.
var candidate = segStart + t * v;
var potentialResults = new Tuple<Point, double>[]
{
Tuple.Create(candidate, (candidate - pnt).LengthSquared),
Tuple.Create(segStart, (segStart - pnt).LengthSquared),
Tuple.Create(segEnd, (segEnd - pnt).LengthSquared),
};
return potentialResults.Minimizer(x => x.Item2).Item1;
}
}
