The efficiency seems not good.

How does the performance of your code compare with Shewchucks widely used triangle code?

Hi, andy, you asked a very good question. About Jonathan's Triangle, it's well know that triangle is the best delaunay triangulation code open to public and it's famous for its refinement implementations. However, triangle is not comparable with Poly2Tri, since triangle generates Delanuany triangles directly, but poly2tri not, as mentaioned in poly2tri's website, polygon delauany triangualtion is not availbe for poly2tri's free public version . If you really won't compare poly2tri with triangle, you may download triangle and poly2tri and compare them with superior.bdm (included in poly2tri's distribution) and superior.poly from Jonathan's site, you will find poly2tri is around 4~5 time faster than triangle. However, it's unfair to triangle, since delaunay triangulation need additional flipping operations to generate delauany triangles. That's why on poly2tri's website, i didn't compare it with triangle.

Frankly speaking, i have no idea about your probelem. So firstly, download the updated version(14/11/2005) and try it again. If you still have problem, please tell me your platform, your compiler and your command line options. Did you try other bdm files?

I also would like to ask someone else here who tried the code, did you have same problem as william mentioned? Thanks for your feedbacks and contributions.
