double Point2tridistace(Point onepoint, Point triangle1,Point triangle2,Point triangle3 ){
    // the point and the vertex of the triangle
    // output the distance
    Point e_normal = calTriNormal(triangle1,triangle2,triangle3);
    return (onepoint[0]*e_normal[0] + onepoint[1]*e_normal[1] + onepoint[2]*e_normal[2]);
