computeIntersection

public void computeIntersection(Point p,
                       Point p1,
                       Point p2)

Description copied from class: LineIntersector

Compute the intersection of a point p and the line p1-p2. This function computes the boolean value of the hasIntersection test. The actual value of the intersection (if there is one) is equal to the value of p.
