Detailed Description
allows operations on any transforms

- 1.40
vtkGeneralTransform is like vtkTransform and vtkPerspectiveTransform, but it will work with any vtkAbstractTransform as input. It is not as efficient as the other two, however, because arbitrary transformations cannot be concatenated by matrix multiplication. Transform concatenation is simulated by passing each input point through each transform in turn.

|
Concatenate the specified transform with the current transformation according to PreMultiply or PostMultiply semantics.

Sets the internal state of the transform to PreMultiply. All subsequent operations will occur before those already represented in the current transformation. In homogeneous matrix notation, M = M*A where M is the current transformation matrix and A is the applied matrix. The default is PreMultiply. Definition at line 123 of file vtkGeneralTransform.h.

Get one of the concatenated transformations as a vtkAbstractTransform. These transformations are applied, in series, every time the transformation of a coordinate occurs. This method is provided to make it possible to decompose a transformation into its constituents, for example to save a transformation to a file. Definition at line 153 of file vtkGeneralTransform.h. |
|
Set the input for this transformation. This will be used as the base transformation if it is set. This method allows you to build a transform pipeline: if the input is modified, then this transformation will automatically update accordingly. Note that the InverseFlag, controlled via Inverse(), determines whether this transformation will use the Input or the inverse of the Input. |

Get the inverse flag of the transformation. This controls whether it is the Input or the inverse of the Input that is used as the base transformation. The InverseFlag is flipped every time Inverse() is called. The InverseFlag is off when a transform is first created. Definition at line 182 of file vtkGeneralTransform.h. |

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.
