你好，我现在做三维场景重建方面的，我用cgal 3.5 中 Surface Reconstruction from Point Set实现的算法来做，在有些数据上没问题，但是有些数据重建之后的图形已经跟原来的图形完全不一样了，刚开始我的点没经过处理，后来我处理之后，重建后的图形还是差不多。。。   我QQ是 770631259

  我刚用CGAL不久，以后希望多多指教

I suggest you use the code from the author of Poisson Surface Reconstruction: http://www.cs.jhu.edu/~misha/Code/PoissonRecon/ <http://www.cs.jhu.edu/%7Emisha/Code/PoissonRecon/>.And there is an out of core version:

   Hi ,there
   I'm very glad that CGAL-3.5 provides such a package, with which we can
   reconstruct surface point set easily.But in my project there're a
   large number
   of point set,100,000 or even 1,000,000 in total.I wonder how i can
   improve the
   performace of my program or whether the package  is proper for my
   project.
   I will really apperciate your help.

In my opinion, CGAL's implementation is just a general version, so the performance could not be as high as a specific one.
