[Paraview] Two questions regarding animations in batch
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.

Re: [Paraview] Two questions regarding animations in batch
Morten,
(i) Use CameraAnimationCue instead of KeyFrameAnimationCue.
(ii) Try using the WarpByVector() filter.

Re: [Paraview] Two questions regarding animations in batch
Thank you, Utkarsh! It tried CameraAnimationCue, but it still segfaulted
with the error "No camera to animate". Therefore, I added
Show(reader)
Render()
before creating a cue. Now it works. However, the resulting movie is just
one black frame lasting for a fraction of a second. How can I tell the
script to add the object itself to the movie and to do it for every frame?
I have over 100 frames in .vtk files.

Re: [Paraview] Two questions regarding animations in batch
Morten,
Look at what the function "AnimateReader" in servermanager.py does.
You're missing the setup of the scene to play over time the time range
provided by the reader.
