Detailed Description

create a grid for a vtkGridTransform.

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

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.

float vtkTransformToGrid::GetDisplacementScale   [inline]
 

Get the scale and shift to convert integer grid elements into real values: dx = scale*di + shift. If the grid is of float type, then scale = 1 and shift = 0.

unsigned long vtkTransformToGrid::GetMTime   [protected, virtual]
 

Return this object's modified time.

Reimplemented from vtkObject.

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.

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.

vtkTransformToGrid* vtkTransformToGrid::New   [static]
 

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

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.

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.

virtual void vtkTransformToGrid::SetGridExtent int   ,
int   ,
int   ,
int   ,
int   ,
int   
[virtual]
 

Get/Set the extent of the grid.

virtual void vtkTransformToGrid::SetGridOrigin float   ,
float   ,
float   
[virtual]
 

Get/Set the origin of the grid.

virtual void vtkTransformToGrid::SetGridScalarType int    [virtual]
 

Get/Set the scalar type of the grid. The default is float.

virtual void vtkTransformToGrid::SetGridSpacing float   ,
float   ,
float   
[virtual]
 

Get/Set the spacing between samples in the grid.

virtual void vtkTransformToGrid::SetInput vtkAbstractTransform   [virtual]
 

Set/Get the transform which will be converted into a grid.

void vtkTransformToGrid::UpdateShiftScale   [protected]
 

Internal method to calculate the shift and scale values which will provide maximum grid precision for a particular integer type.
