Detailed Description

transform points and associated normals and vectors.

Date:

2001/10/11 13:37:20

Revision:

1.39

vtkTransformFilter is a filter to transform point coordinates, and associated point normals and vectors. Other point data is passed through the filter.

An alternative method of transformation is to use vtkActor's methods to scale, rotate, and translate objects. The difference between the two methods is that vtkActor's transformation simply effects where objects are rendered (via the graphics pipeline), whereas vtkTransformFilter actually modifies point coordinates in the visualization pipeline. This is necessary for some objects (e.g., vtkProbeFilter) that require point coordinates as input.

Member Function Documentation

vtkTransformFilter* vtkTransformFilter::New (    )  [static]

Instantiate object with no start, end, or progress methods. Reimplemented from vtkPointSetSource.

virtual const char* vtkTransformFilter::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 vtkPointSetToPointSetFilter.

int vtkTransformFilter::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 vtkPointSetToPointSetFilter.

virtual int vtkTransformFilter::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 vtkPointSetToPointSetFilter.

vtkTransformFilter* vtkTransformFilter::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 vtkPointSetToPointSetFilter.

void vtkTransformFilter::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 vtkSource.

unsigned long vtkTransformFilter::GetMTime (    )  [virtual]

Return the MTime also considering the transform. Reimplemented from vtkObject.

virtual void vtkTransformFilter::SetTransform (  vtkAbstractTransform *    )  [virtual]

Specify the transform object used to transform points.

virtual vtkAbstractTransform* vtkTransformFilter::GetTransform (    )  [virtual]

Specify the transform object used to transform points.

void vtkTransformFilter::Execute (    )  [protected, virtual]

This method is the old style execute method Reimplemented from vtkSource.
