Hi Sebastian,

Our problem we have a simple shape of beam (thin plate) is deforming, 

one of our solver is particle based solver and it send  surface   points of 
the beam to other mesh-based solver. The mesh based solver takes these points and needs 
to create the surface mesh.  But we insist on the original points, otherwise we have 
a lot complications.

Those points might create a concave shape, I think that convex shape is not guaranteed.

Thanks,

Do your points have some particular properties (on a convex shape, inside a set of planes, ...)?

Hi Sebastian,

Thanks for answer,

Is there any other way to do in CGAL, just give surface points and get reconstructed mesh
connecting those points?

Thanks,

       Hi,

       I am trying to use points and normals to reconstruct surface
       mesh, I follow "Surface
       Reconstruction from Point Sets" section in CGAL.

       I have some input points and its normal. Since algorithm solves
       eliptic equation of
       Poisson reconstruction and it gives a approximate surface.

       Is it possible to reconstruct mesh that its vertices are
        exactly the same with input?


   This is not possible with this algorithm.

   Sebastien.



       if you can help me, I would be really glad,

       Thanks,
