Hi all. 
I'm trying to construct face from DICOM images. Till now I've successfully
extracted Points and normals, you can get the ply file from here 

this is the point cloud result 

Now I'm trying to convert Points to mesh, for that I'm using 

 vtkSmartPointer<vtkDelaunay2D> delaunay =

But this function is not able to construct the mesh properly. I tried
changing all the parameters for Delaunay2D but, got no success. I also tried
using vtkSurfaceReconstruct and I get some strange result. 
In meshlab I can construct a smooth surface by using Poisson Surface
Reconstruct, and wanted to get the same result using vtk. 

Delaunay2D result 

MeshLab result 

Please help me to figure out what's wrong I'm doing and also any solution to
construct a smooth surface from this point cloud will be really appreciated. 
Thank you.
