Displaying a Mesh based on pointcloud data

I am sampling data from the point cloud and trying to display the selected points using a mesh renderer.

I have the data but I can't visualize it. I am using the Augmented Reality application as template.

I am doing the point saving and mesh population in a coroutine. There are no errors but I can't see any resulting mesh. I am wondering if there is a conflict with an existing mesh component from the point cloud example that I use for creating the cloud.

I pick a point on screen (touch) and use the index to find coordinates and populate a Vector3[]. The mesh receiveds the vertices( 5000 points out of 500000 in the point cloud)

this is where I set the mesh:

 if (m_updateSubPointsMesh)
 {
      int[] indices = new int[ctr];
      for (int i = 0; i < ctr; ++i)
      {
           indices[i] = i;
                            }
           m_submesh.Clear();
           m_submesh.vertices = m_subpoints;
           int vertsInMesh = m_submesh.vertexCount;

           m_submesh.SetIndices(indices, MeshTopology.Points, 0);

       }
      m_subrenderer.material.SetColor("_SpecColor", Color.yellow);

I am using Unity pro 5.3.3 and VS 2015 on windows 10.

Comments and advice are very much appreciated even if they are not themselves a solution.

I sort it out. The meshing was right it turn out to be a bug on a transform (not tango-defined). The mesh was rendered in another point. Had to walk around to find it.

Thanks

You must convert the Tango mesh data to mesh data for unity, its not structured in the same way I believe its the triangles thats different. You also need to set triangles and normals to the mesh.
