Hi, I would like to animate a parameter with a python programmable filter using keyframes. In this simple example, I just want to rescale a scalar variable by a constant factor (alpha). But I want to animate this factor. Here is my filter:
from paraview.vtk import dataset_adapter as DA self.SetParameter('alpha', 0.1) pdi = self.GetInputDataObject(0,0) pdo = self.GetOutputDataObject(0) pdo.CopyAttributes(pdi) d = alpha * inputs[0].PointData['temperature'] arr = DA.numpyTovtkDataArray(d, 'temperature_scaled') pdo.GetPointData().AddArray(arr) This script works, but I can't set alpha using keyframes. It just doesn't show up in the animation view. Perhaps I have understood what the whole "SetParameter" framework does. What is the point of setting these parameters if they can't be modified from outside the filter? Thanks in advance for your help. -Ryan
