// .NAME vtkIdentityTransform - a transform that doesn't do anything
|
|
// .SECTION Description
|
|
// vtkIdentityTransform is a transformation which will simply pass coordinate
|
|
// data unchanged. All other transform types can also do this, however,
|
|
// the vtkIdentityTransform does so with much greater efficiency.
|
|
// .SECTION see also
