Usage

From source file:de.pixida.logtest.designer.automaton.LineIntersector.java

static Point2D calculateIntersection(final Point2D point, final Point2D vec, final Line line) {
    final Point2D q = new Point2D(line.getStartX(), line.getStartY());
    final Point2D w = new Point2D(line.getEndX(), line.getEndY()).subtract(q);

    // q + t1 * w = point + t2 * vec => q - point = (vec w) (t2 -t1)^T
    final double det = det2x2LineWiseDefined(vec.getX(), w.getX(), vec.getY(), w.getY());
    final double epsilon = 1E-5;
    if (Math.abs(det) < epsilon) {
        return null;
    }/*from   w w w  . jav  a2  s  . c om*/
    final double detInv = 1.0 / det;
    final double t2 = det2x2LineWiseDefined(q.getX() - point.getX(), w.getX(), q.getY() - point.getY(),
            w.getY()) * detInv;

    final Point2D intersection = vec.multiply(t2).add(point);
    return intersection;
