|
* @brief Divergence of a vector field.
|
||
|
|
*
|
||
|
|
* vtkImageDivergence takes a 3D vector field
|
||
|
|
* and creates a scalar field which
|
||
|
|
* which represents the rate of change of the vector field.
|
||
|
|
* The definition of Divergence:
|
||
|
|
* Given V = P(x,y,z), Q(x,y,z), R(x,y,z),
|
||
|
|
* Divergence = dP/dx + dQ/dy + dR/dz.
