vtkTessellatedBoxSource

Section: Visualization Toolkit Graphics Classes

# Usage

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.

To create an instance of class vtkTessellatedBoxSource, simply invoke its constructor as follows

      obj = vtkTessellatedBoxSource

# Methods

The class vtkTessellatedBoxSource has several methods that can be used. They are listed below. Note that the documentation is translated automatically from the VTK sources, and may not be completely intelligible. When in doubt, consult the VTK website. In the methods listed below, `obj` is an instance of the vtkTessellatedBoxSource class.

- `string = obj.GetClassName ()`
- `int = obj.IsA (string name)`
- `vtkTessellatedBoxSource = obj.NewInstance ()`
- `vtkTessellatedBoxSource = obj.SafeDownCast (vtkObject o)`
- `obj.SetBounds (double , double , double , double , double , double )` - Set the bounds of the box. See GetBounds() for a detail description.
  Precondition:
    xmin<=xmax && ymin<=ymax && zmin<zmax
- `obj.SetBounds (double a[6])` - Set the bounds of the box. See GetBounds() for a detail description.
  Precondition:
    xmin<=xmax && ymin<=ymax && zmin<zmax
- `double = obj. GetBounds ()` - Bounds of the box in world coordinates. This a 6-uple of xmin,xmax,ymin, ymax,zmin and zmax. Initial value is (-0.5,0.5,-0.5,0.5,-0.5,0.5), bounds of a cube of length 1 centered at (0,0,0). Bounds are defined such that xmin<=xmax, ymin<=ymax and zmin<zmax.
  Postcondition:
    xmin<=xmax && ymin<=ymax && zmin<zmax
- `obj.SetLevel (int )` - Set the level of subdivision of the faces.
  Precondition:
    positive_level: level>=0
- `int = obj.GetLevel ()` - Level of subdivision of the faces. Initial value is 0.
  Postcondition:
    positive_level: level>=0
- `obj.SetDuplicateSharedPoints (int )` - Flag to tell the source to duplicate points shared between faces (vertices of the box and internal edge points). Initial value is false. Implementation note: duplicating points is an easier method to implement than a minimal number of points.
- `int = obj.GetDuplicateSharedPoints ()` - Flag to tell the source to duplicate points shared between faces (vertices of the box and internal edge points). Initial value is false. Implementation note: duplicating points is an easier method to implement than a minimal number of points.
- `obj.DuplicateSharedPointsOn ()` - Flag to tell the source to duplicate points shared between faces (vertices of the box and internal edge points). Initial value is false. Implementation note: duplicating points is an easier method to implement than a minimal number of points.
- `obj.DuplicateSharedPointsOff ()` - Flag to tell the source to duplicate points shared between faces (vertices of the box and internal edge points). Initial value is false. Implementation note: duplicating points is an easier method to implement than a minimal number of points.
- `obj.SetQuads (int )` - Flag to tell the source to generate either a quad or two triangle for a set of four points. Initial value is false (generate triangles).
- `int = obj.GetQuads ()` - Flag to tell the source to generate either a quad or two triangle for a set of four points. Initial value is false (generate triangles).
- `obj.QuadsOn ()` - Flag to tell the source to generate either a quad or two triangle for a set of four points. Initial value is false (generate triangles).
- `obj.QuadsOff ()` - Flag to tell the source to generate either a quad or two triangle for a set of four points. Initial value is false (generate triangles).
