List of closestPoint() Examples

Examples of closestPoint()

com.vividsolutions.jts.geom.LineSegment.closestPoint()
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
org.apache.commons.math3.geometry.euclidean.threed.Line.closestPoint()
Compute the point of the instance closest to another line. @param line line to check against the instance @return point of the instance closest to another line
