Hello,

Do you need nubers, of picture?

not voronoi tesselation diagram.

They are dual, one uniquely determines the other, so if you have
Delaunay triangulation, creating Voronoi tesselation is "easy".

> It seems the voro++[2] is what I am looking for, but the result seems
not good because I didn't see any spheres.

I don't know voro++, but if I remember correctly, Paraview could do this.
If not natively, you can always create the Voronoi diagram and "manually" display the lines together with spheres.

Cheers
Jan
