Detailed Description

Create a polygonal representation of a box with a given level of subdivision.

vtkTessellatedBoxSource creates a axis-aligned box defined by its bounds and a level of subdivision. Connectivity is strong: points of the vertices and inside the edges are shared between faces. In other words, faces are connected. Each face looks like a grid of quads, each quad is composed of 2 triangles. Given a level of subdivision `l', each edge has `l'+2 points, `l' of them are internal edge points, the 2 other ones are the vertices. Each face has a total of (`l'+2)*(`l'+2) points, 4 of them are vertices, 4*`l' are internal edge points, it remains `l'^2 internal face points.

This source only generate geometry, no DataArrays like normals or texture coordinates.
