Here an example to compute the gradient of var, and store the result as new_var.
g = vtk.vtkGradientFilter() > g.SetInput(Bloc) > g.SetInputScalars(0, var) > g.SetResultArrayName(new_var) > g.Update() > > Bloc.GetPointData().AddArray(g.GetOutput().GetPointData().GetArray(new_var)) > Maybe you forgot the "Update" ? 2010/7/2 Adriano Gagliardi <[email protected]> > > Does anyone have an example of using vtkGradientFilter to compute the > gradients of a single vector in your data-set? I've tried using > SetInputScalars, but it tells me that there is no input array,. although > the > array I pass it does exist. > > =================================== > > Adriano Gagliardi MEng PhD > Business Sector Leader > Computational Aerodynamics > Aircraft Research Association Ltd. > Manton Lane > Bedford > > Tel: 01234 32 4644 > E-mail: [email protected] > Url: www.ara.co.uk > > > ********************************************************************** > This email contains information that is private and confidential and is > intended only for the addressee. > If you are not the intended recipient please delete it and notify us > immediately by e-mailing the sender. > Note: All email sent to or from this address may be accessed by someone > other than the recipient, for > system management and security reasons. > Aircraft Research Association Ltd.
