  2. abstract def computeIntersection(p: Coordinate, p1: Coordinate, p2: Coordinate): Unit

    Compute the intersection of a point p and the line p1-p2.

    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.
