|
|
* @brief Computes a vector field using sobel functions.
|
||
|
|
*
|
||
|
|
* 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.
