closestPoint method
Computes the closest point on this line segment to another point. @param p the point to find the closest point to @return a Coordinate which is the closest point on the line segment to the point p
Implementation
Coordinate closestPoint(Coordinate p) {
double factor = projectionFactor(p);
if (factor > 0 && factor < 1) {
return projectCoord(p);
}
double dist0 = p0.distance(p);
double dist1 = p1.distance(p);
if (dist0 < dist1) return p0;
return p1;
}
