[Paraview] Two questions regarding animations in batch

[Morten Olsen]

Hi all,

I'm new to the batch interface and trying to batch animations using
pvbatch. I have read the wiki and searched through the mailing list for
information, and found many useful answers. However, I'm stuck with two
questions:

i) The following script segfaults with the error message posted at the end
of this email. Any idea how to solve it?

#!/usr/local/bin/pvbatch

from paraview.simple import *

reader = PVDReader(FileName='vtkfiles/displacement.pvd')

scene = GetAnimationScene()
view = GetActiveView()

cue = servermanager.animation.KeyFrameAnimationCue()
cue.StartTime = 0.0
cue.EndTime = 1.0
cue.AnimatedProxy = view

keyf0 = servermanager.animation.CameraKeyFrame()
keyf0.KeyTime = 0.0
keyf1 = servermanager.animation.CameraKeyFrame()
keyf1.KeyTime = 1.0
cue.KeyFrames = [keyf0, keyf1]

movie = servermanager.animation.AnimationScene()
movie.ViewModules = [view]
movie.Cues.append(cue)

movieWriter = servermanager.vtkSMAnimationSceneImageWriter()
movieWriter.SetFrameRate(24)
movieWriter.SetFileName("movie.avi")
movieWriter.SetAnimationScene(movie.SMProxy)
movieWriter.Save()


ii) How can I add the warp by vector filter?

By the way, I'm using the standard 3.14.1 64-bit edition of Paraview on
Linux Mint Maya.

Here's the segfault output:

ERROR: In
/build/buildd/paraview-3.14.1/ParaViewCore/ClientServerCore/vtkPVCameraKeyFrame.cxx,
line 81
vtkPVCameraKeyFrame (0x2938dc0): This keyframe can only be added to
vtkPVCameraCueManipulator.
