主题：[cgal-discuss] Problem on Poisson Surface reconstruction
-------------------------------------------------


Hello,

I'm using CGAL's Surface Mesher generate surface on 3D points. It works well 

on the dataset in examples. However when I test it on my own data errors occurs.

terminate called after throwing an instance of 'CGAL::Assertion_exception'

what(): CGAL ERROR: assertion violation!

File: ../myLibs/CGAL-4.2/include/CGAL/Surface_mesher/Surface_mesher.h

Line: 249

Explanation: (-4.89829 2.14556 3.70213) is already inserted on surface.

The program has unexpectedly finished.

Can any one can help me？ 

Thank you very much!
