get triangle information and dump mesh obj

Hi,
I am loading my own point cloud file (xyz format) and calculating the triangulation. I need the triangle faces created by the algorithm, but I can get only a simplex i.e. a tetra. I tried to use getTriangleCount() method which gets all four triangles from tetra and then pass all the triangles thus obtained as faces in the obj. I know its incorrect since all the triangles formed by tetra cannot be faces to the mesh and obviosly the dumped result is also wrong.
Could you tell me hoe do I correctly get only faces of the mesh formed post triangulation?

thanks

Do you have any solution to the question? I encountered the same problem and want to discuss something.
Could you tell me how to get the mesh result?

I encountered the same problem. Have you solved this problem now? Could you tell me the solution to this question? Thank you!
