I don't know if I'm in the right place to ask this question!

I have two 3D modeling and I want verify the Euler-Poincaré Formula on them that include face,holes, vertex, etc. Anyone knows about that?

It is not entirely clear what you are asking, but the Euler formula is V - E + F = 2 (1-g), where g is the number of holes (the genus). Perhaps you also have cavities? Then look at this San José State exposition.

  • $\begingroup$ That what I want! I want to use those Euler formulas for those 3D objects $\endgroup$ – Ja_cpp Aug 21 '17 at 21:55

  • $\begingroup$ @DuarteFarrajotaRamos I didn't upvote it. I already know those formulas but my question is how can I apply them $\endgroup$ – Ja_cpp Aug 22 '17 at 7:43
