3dArc_3dArc_Intersections

A general algoritme to find 3d intersections. Works also for parallel arc planes.

        //! Arc A
        gp_Pnt pa0_in{0,0,0};
        gp_Pnt pa1_in{50,50,0};
        gp_Pnt pa2_in{100,0,0};
        OBJECT *ArcA = new OBJECT(arc_3p,pa0_in,pa1_in,pa2_in);
        
        //! Arc B
        gp_Pnt pb0_in{0,100,0};
        gp_Pnt pb1_in{50,50,0};
        gp_Pnt pb2_in{100,100,0};
        OBJECT *ArcB = new OBJECT(arc_3p,pb0_in,pb1_in,pb2_in);
   
        gp_PntVec pvec;
        ArcA->getIntersections(*ArcB,pvec,1);

        for(unsigned int i=0; i<pvec.size(); i++){
            //! Intersections:
            pvec[i]
        }
