Question by Negagames · Jan 01, 2014 at 04:45 AM · mathcubemesh verticesvertice manipulation

Imported cube vertex count different than expected

I made a cube in maya, with width, height ad depth divisions set 16. I was expecting a cube with a total of 16^3, 4096 vertices, but on importing and attempting to normalize the cube, I got a return of 1734 vertices. How do I calculate the vertices of not cubing the divisions?

It depends on if your sub-quads reuse verts or copies them. Are the numbers different from what maya showed or just different from what you calculated?

With reusing verts on every face, but not on the edges, I expect 6 * 17*17 = 1734 verts

Different than calculated, where did you get the 17s from

if you have 2 divisions, you have 3 * 3 verts:

 x x x
 x x x
 x x x

so if you have 16 divisions, you have 17*17 verts.... per face

Ok, and the 6?

6 faces of the cube. front/back, left/right, top/bottom

You seem to think that the subdivisions are some kind of structure that is also inside the cube. It's just on the surface of the cube. There is no vertex inside the cube.
