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.

vtkAbstractTransform* vtkAbstractTransform::GetInverse | ( | ) |
Get the inverse of this transform. If you modify this transform, the returned inverse transform will automatically update. If you want the inverse of a vtkTransform, you might want to use GetLinearInverse() instead which will type cast the result from vtkAbstractTransform to vtkLinearTransform.
void vtkAbstractTransform::SetInverse | ( | vtkAbstractTransform * | transform | ) |
Set a transformation that this transform will be the inverse of. This transform will automatically update to agree with the inverse transform that you set.
|
pure virtual |
Invert the transformation.
Implemented in vtkLandmarkTransform, vtkTransform, vtkPerspectiveTransform, vtkIdentityTransform, vtkGeoTransform, vtkGeneralTransform, vtkMatrixToLinearTransform, vtkMatrixToHomogeneousTransform, vtkGeoSphereTransform, and vtkWarpTransform.
void vtkAbstractTransform::DeepCopy | ( | vtkAbstractTransform * | ) |
Copy this transform from another of the same type.
void vtkAbstractTransform::Update | ( | ) |
Update the transform to account for any changes which have been made. You do not have to call this method yourself, it is called automatically whenever the transform needs an update.
|
pure virtual |
This will calculate the transformation without calling Update. Meant for use only within other VTK classes.
Implemented in vtkGeneralTransform, vtkLinearTransform, vtkHomogeneousTransform, vtkIdentityTransform, vtkWarpTransform, vtkGeoTransform, and vtkGeoSphereTransform.

This will transform a point and, at the same time, calculate a 3x3 Jacobian matrix that provides the partial derivatives of the transformation at that point. This method does not call Update. Meant for use only within other VTK classes.
Implemented in vtkGeneralTransform, vtkLinearTransform, vtkIdentityTransform, vtkHomogeneousTransform, vtkWarpTransform, vtkGeoTransform, and vtkGeoSphereTransform.

virtual |
Check for self-reference. Will return true if concatenating with the specified transform, setting it to be our inverse, or setting it to be our input will create a circular reference. CircuitCheck is automatically called by SetInput(), SetInverse(), and Concatenate(vtkXTransform *). Avoid using this function, it is experimental.
Reimplemented in vtkPerspectiveTransform, vtkTransform, and vtkGeneralTransform.
unsigned long vtkAbstractTransform::GetMTime | ( | ) |
Override GetMTime necessary because of inverse transforms.
