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.

| static vtkTessellatedBoxSource* vtkTessellatedBoxSource::New | ( | ) | [static] |
Create an object with Debug turned off, modified time initialized to zero, and reference counting on.
Reimplemented from vtkPolyDataAlgorithm.
| static int vtkTessellatedBoxSource::IsTypeOf | ( | const char * | name | ) | [static] |
Return 1 if this class type is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h.
