the number of tetrahedra may run fron O(n) to O(n^2)
even without inner vertices

In usual meshes (with inner vertices) it's about 7 or 8 times
the number of vertices

Hi,

We have Euler's formula that relates the number of vertices to the number of
faces, and on average a triangle mesh would have twice the number of
triangles as the number of vertices. Can we say something on the average of
the number of tetrahedra (no additional inner points)?
