Detailed Description

allows operations on any transforms

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.

void vtkGeneralTransform::Concatenate ( vtkMatrix4x4 * matrix )

inline

Concatenates the matrix with the current transformation according to PreMultiply or PostMultiply semantics.

Definition at line 101 of file vtkGeneralTransform.h.

void vtkGeneralTransform::Concatenate ( const double elements[16] )

inline

Concatenates the matrix with the current transformation according to PreMultiply or PostMultiply semantics.

Definition at line 103 of file vtkGeneralTransform.h.

void vtkGeneralTransform::Concatenate ( vtkAbstractTransform * transform )

Concatenate the specified transform with the current transformation according to PreMultiply or PostMultiply semantics. The concatenation is pipelined, meaning that if any of the transformations are changed, even after Concatenate() is called, those changes will be reflected when you call TransformPoint().

void vtkGeneralTransform::PreMultiply ( )

inline

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 120 of file vtkGeneralTransform.h.

void vtkGeneralTransform::PostMultiply ( )

inline

Sets the internal state of the transform to PostMultiply. All subsequent operations will occur after those already represented in the current transformation. In homogeneous matrix notation, M = A*M where M is the current transformation matrix and A is the applied matrix. The default is PreMultiply.

Definition at line 131 of file vtkGeneralTransform.h.

int vtkGeneralTransform::GetNumberOfConcatenatedTransforms ( )

inline

Get the total number of transformations that are linked into this one via Concatenate() operations or via SetInput().

Definition at line 139 of file vtkGeneralTransform.h.

vtkAbstractTransform* vtkGeneralTransform::GetConcatenatedTransform ( int i )

inline

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 150 of file vtkGeneralTransform.h.

void vtkGeneralTransform::SetInput ( vtkAbstractTransform * input )

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.

vtkAbstractTransform* vtkGeneralTransform::GetInput ( )

inline

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.

Definition at line 171 of file vtkGeneralTransform.h.

int vtkGeneralTransform::GetInverseFlag ( )

inline

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 179 of file vtkGeneralTransform.h.

void vtkGeneralTransform::Push ( )

inline

Pushes the current transformation onto the transformation stack.

Definition at line 185 of file vtkGeneralTransform.h.

void vtkGeneralTransform::Pop ( )

	)

virtual

This will calculate the transformation as well as its derivative without calling Update. Meant for use only within other VTK classes.

Implements vtkAbstractTransform.

int vtkGeneralTransform::CircuitCheck ( vtkAbstractTransform * transform )

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.
