Detailed Description

Computes a vector field using sobel functions.

Revision:
1.22
Thanks:
Thanks to C. Charles Law who developed this class.
vtkImageSobel3D computes a vector field from a scalar field by using Sobel functions. The number of vector components is 3 because the input is a volume. Output is always floats. A little creative liberty was used to extend the 2D sobel kernels into 3D.

Member Function Documentation

vtkImageSobel3D* vtkImageSobel3D::New   [static]
 

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

Reimplemented from vtkImageSpatialFilter.

virtual const char* vtkImageSobel3D::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 vtkImageSpatialFilter.

int vtkImageSobel3D::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 vtkImageSpatialFilter.

virtual int vtkImageSobel3D::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 vtkImageSpatialFilter.

vtkImageSobel3D* vtkImageSobel3D::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 vtkImageSpatialFilter.

void vtkImageSobel3D::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 vtkImageSpatialFilter.

void vtkImageSobel3D::operator= const vtkImageSobel3D &    [inline, protected]
 

Definition at line 73 of file vtkImageSobel3D.h.

void vtkImageSobel3D::ThreadedExecute vtkImageData   inData,
vtkImageData   outData,
int    outExt[6],
int    id
[protected, virtual]
 

If the subclass does not define an Execute method, then the task will be broken up, multiple threads will be spawned, and each thread will call this method. It is public so that the thread functions can call this method.

Reimplemented from vtkImageToImageFilter.

void vtkImageSobel3D::ExecuteInformation vtkImageData   inData,
vtkImageData   outData
[protected, virtual]
 

Reimplemented from vtkImageSpatialFilter.

void vtkImageSobel3D::ExecuteInformation   [inline, protected, virtual]
 

Reimplemented from vtkImageSpatialFilter.
