[Paraview] Moving slice animation

[Adriano Gagliardi]

Utkarsh,

I made that change you suggested and it removed the error message. However,
when using the Origin as the AnimatedPropertyName, it was ignoring all but
the first value of the vector I used for the KeyValues e.g.:

keyf1.KeyValues = [0,0,0]
keyf2.KeyValues = [1,1,0]

It would only recognise the first component of the vector and animate along
that, which didn't do anything as you'd expect (apart from move the arrow
widget). I got round this by using Offset instead of Origin and that worked
as I expected. Code is below:

movie = servermanager.animation.AnimationScene()
movie.ViewModules = (GetActiveView())
cue = servermanager.animation.KeyFrameAnimationCue()
cue.AnimatedProxy = sl.SliceType
cue.AnimatedPropertyName = "Offset"
keyf1 = servermanager.animation.CompositeKeyFrame()
keyf1.Interpolation = "Ramp"
keyf1.KeyTime = 0
keyf1.KeyValues = [0,0,0]
keyf2 = servermanager.animation.CompositeKeyFrame()
keyf2.KeyTime = 1.0
keyf2.KeyValues = [0.5,0.5,0]
cue.KeyFrames = [keyf1,keyf2]
movie.NumberOfFrames = 20
movie.Cues = [cue]

movie_writer = servermanager.vtkSMAnimationSceneImageWriter()
movie_writer.SetFileName("temp.avi")
movie_writer.SetFrameRate(3)
movie_writer.SetQuality(2)
movie_writer.SetMagnification(2)
movie_writer.SetAnimationScene(movie.SMProxy)
movie_writer.Save()

Hopefully this can give others a helping hand in the future.

Cheers,

Adriano

Try:

cue.AnimatedProxy = slice.SliceType
cue.AnimatedPropertyName = "Origin"
