// .NAME vtkImageDivergence - Divergence of a vector field.
|
|
// .SECTION Description
|
|
// 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.
