Detailed Description

create a grid for a vtkGridTransform.

Date:
2000/12/10 20:08:27
Revision:
1.3
Thanks:
Thanks to David G. Gobbi who developed this class.
vtkTransformToGrid takes any transform as input and produces a grid for use by a vtkGridTransform. This can be used, for example, to invert a grid transform, concatenate two grid transforms, or to convert a thin plate spline transform into a grid transform.

Member Function Documentation

vtkTransformToGrid* vtkTransformToGrid::New (    )  [static]
 

Instantiate object with no start, end, or progress methods.

Reimplemented from vtkImageSource.

virtual const char* vtkTransformToGrid::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 vtkImageSource.

int vtkTransformToGrid::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 vtkImageSource.

virtual int vtkTransformToGrid::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 vtkImageSource.

vtkTransformToGrid* vtkTransformToGrid::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 vtkImageSource.

void vtkTransformToGrid::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.
