// .NAME vtkImageSobel3D - Computes a vector field using sobel functions.
// .SECTION Description
// 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 doubles. A little creative
// liberty was used to extend the 2D sobel kernels into 3D.
