  10. I have a series of vertex points for a complex non-self intersecting 
  11. polygon structure and would like to divide it along a cut-line.  If
  12. you have any algorithms which might help please forward to 
  13. mpe@shamash.cdc.com. 
  14.  
  15. Thank you for any help you might be able to offer.

  17. Example structure:
  18.  
  19.                X*********************X          X******************X
  20.                *                     *          *                  *
  21.                *                     *          *    X*******X     *
  22.                *                     *          *    *       *     *
  23. cutline -----------------------------------------------------------------
  24.                *                     *          *    *       *     *
  25.                *                     X**********X    *       X*****X
  26.                *                                     *
  27.                X*************************************X

  29. This would result in four smaller polygon structures...
