This is a question regarding the library cgal and geomviewer, which can be found at http://www.cgal.org/

Here is the problem:

1. I want to be able to display line segments with geomviewer programtically. I am able to peform triangulation and output the faces to the geomviewer. However, I cannot fathom how to stream in a series of lines.
2. Currently the triangulation is streamed as follows:
Code:
    CGAL::Geomview_stream gv(CGAL::Bbox_3(-Xbox/2.0, -Ybox/2.0, -Zbox/2.0, Xbox/2.0,  Ybox/2.0, Zbox/2.0));
    gv.set_line_width(4);
    gv.set_trace(true);
    gv.set_bg_color(CGAL::Color(0, 200, 200));
    gv.clear();
   gv << T;
    sleep(50);
3. However I want to simply included a series of line segments, however I can only do one at a time. with for example:

Code:
Point3 myPointsource(0.0,0.0,0.0);
      Point3 myPointtarget(Normal_base[0]*5,Normal_base[1]*5,Normal_base[2]*5);
      Line3 mySegmentNormal(myPointsource,myPointtarget);
      //gv.set_wired(true);
      gv << mySegmentNormal;
4. How do I create the necessary structures such that I can send a whole series of line sections off and are displayed.

Thanks
