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.

Member Function Documentation

static vtkTessellatedBoxSource* vtkTessellatedBoxSource::New ( ) [static]

Create an object with Debug turned off, modified time initialized to zero, and reference counting on.

Reimplemented from vtkPolyDataAlgorithm.

virtual const char* vtkTessellatedBoxSource::GetClassName ( ) [virtual]

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.

Reimplemented from vtkPolyDataAlgorithm.

virtual int vtkTessellatedBoxSource::IsA ( const char * name ) [virtual]

Return 1 if this class 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.

Reimplemented from vtkPolyDataAlgorithm.

virtual void vtkTessellatedBoxSource::PrintSelf	(	ostream &	os,
		vtkIndent	indent
