Detailed Description

convert a matrix to a transform.

Date:

2001/10/11 13:36:17

Revision:

1.5

This is a very simple class which allows a vtkMatrix4x4 to be used in place of a vtkHomogeneousTransform or vtkAbstractTransform. For example, if you use it as a proxy between a matrix and vtkTransformPolyDataFilter then any modifications to the matrix will automatically be reflected in the output of the filter.

Member Function Documentation

vtkMatrixToHomogeneousTransform* vtkMatrixToHomogeneousTransform::New (    )  [static]

Create an object with Debug turned off, modified time initialized to zero, and reference counting on. Reimplemented from vtkObject.

virtual const char* vtkMatrixToHomogeneousTransform::GetClassName (    )  [virtual]

Return the class name as a string. This method is defined in all subclasses of vtkObject with the vtkTypeMacro found in vtkSetGet.h. Reimplemented from vtkHomogeneousTransform.

int vtkMatrixToHomogeneousTransform::IsTypeOf (  const char *    type )  [static]

Return 1 if this class type is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h. Reimplemented from vtkHomogeneousTransform.

virtual int vtkMatrixToHomogeneousTransform::IsA (  const char *    type )  [virtual]

Return 1 if this class is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h. Reimplemented from vtkHomogeneousTransform.

vtkMatrixToHomogeneousTransform* vtkMatrixToHomogeneousTransform::SafeDownCast (  vtkObject *    o )  [static]

Will cast the supplied object to vtkObject* is this is a safe operation (i.e., a safe downcast); otherwise NULL is returned. This method is defined in all subclasses of vtkObject with the vtkTypeMacro found in vtkSetGet.h. Reimplemented from vtkHomogeneousTransform.

void vtkMatrixToHomogeneousTransform::PrintSelf (  ostream &    os, vtkIndent    indent )  [virtual]

Methods invoked by print to print information about the object including superclasses. Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes. Reimplemented from vtkHomogeneousTransform.

virtual void vtkMatrixToHomogeneousTransform::SetInput (  vtkMatrix4x4 *    )  [virtual]

virtual vtkMatrix4x4* vtkMatrixToHomogeneousTransform::GetInput (    )  [virtual]

void vtkMatrixToHomogeneousTransform::Inverse (    )  [virtual]

The input matrix is left as-is, but the transformation matrix is inverted. Reimplemented from vtkAbstractTransform.

unsigned long vtkMatrixToHomogeneousTransform::GetMTime (    )  [virtual]

Get the MTime: this is the bit of magic that makes everything work. Reimplemented from vtkAbstractTransform.

vtkAbstractTransform* vtkMatrixToHomogeneousTransform::MakeTransform (    )  [virtual]

Make a new transform of the same type. Reimplemented from vtkAbstractTransform.

void vtkMatrixToHomogeneousTransform::SetMatrix (  vtkMatrix4x4 *    matrix )  [inline]

This method is deprecated. Definition at line 90 of file vtkMatrixToHomogeneousTransform.h.

void vtkMatrixToHomogeneousTransform::InternalUpdate (    )  [protected, virtual]

Perform any subclass-specific Update. Reimplemented from vtkAbstractTransform.

void vtkMatrixToHomogeneousTransform::InternalDeepCopy (  vtkAbstractTransform *    transform )  [protected, virtual]

Perform any subclass-specific DeepCopy. Reimplemented from vtkHomogeneousTransform.
