From source file:orchestration.path.RectShape.java

@Override
public boolean collidesWith(PlannerShape shape) {
    Polygon otherPoly = shape.getPolygon();

    // quick collision check
    if (!otherPoly.intersects(poly.getBounds()))
        return false;

    // check all line segments for intersection
    for (int i = 0; i < poly.npoints; i++) {
        Vector3D p = createPoint(poly.xpoints[i], poly.ypoints[i]);
        Vector3D r = createLine(p, poly.xpoints[(i + i) % poly.npoints], poly.xpoints[(i + i) % poly.npoints]);

        for (int j = 0; j < otherPoly.npoints; j++) {
            Vector3D q = createPoint(otherPoly.xpoints[i], otherPoly.ypoints[i]);
            Vector3D s = createLine(q, otherPoly.xpoints[(i + i) % otherPoly.npoints],
                    otherPoly.xpoints[(i + i) % otherPoly.npoints]);

    // check if one polygon completely contains the other
    if (otherPoly.contains(poly.xpoints[0], poly.ypoints[0]))
