Detailed Description

superclass for all geometric transformations

vtkAbstractTransform is the superclass for all VTK geometric transformations. The VTK transform hierarchy is split into two major branches: warp transformations and homogeneous (including linear) transformations. The latter can be represented in terms of a 4x4 transformation matrix, the former cannot.

Transformations can be pipelined through two mechanisms:

1) GetInverse() returns the pipelined inverse of a transformation i.e. if you modify the original transform, any transform previously returned by the GetInverse() method will automatically update itself according to the change.

2) You can do pipelined concatenation of transformations through the vtkGeneralTransform class, the vtkPerspectiveTransform class, or the vtkTransform class.
