[Paraview] Moving slice animation

[Adriano Gagliardi]

Dear All,

I've decided to revisit a problem that got me stuck a long time ago. I'd
like to animate a slice moving through a fluid, but I'm stuck on the syntax
for the cue.AnimatedPropertyName I need. I followed the example from the
Wiki as closely as possible. I only wish to animate the y component of the
origin, but since I can't pass that scalar as an AnimatedPropertyName, I am
defining the KeyValue as a vector instead. Is this correct? Secondly, after
I execute the following code, I get this error message:

ERROR: In
/usr/people/gagliard/Paraview/FILES/ParaView3/Servers/ServerManager/vtkSMRam
pKeyFrameProxy.cxx, line 53
vtkSMRampKeyFrameProxy (0x10e34270): Cue does not have domain or property
set!

>>> slice = GetActiveSource()
>>> movie = servermanager.animation.AnimationScene()
>>> movie.ViewModules = (GetActiveView())
>>> cue = servermanager.animation.KeyFrameAnimationCue()
>>> cue.AnimatedProxy = slice
>>> cue.AnimatedPropertyName = "SliceType.Origin"
>>> movie.Cues = [cue]
>>> keyf1 = servermanager.animation.CompositeKeyFrame()
>>> keyf1.Interpolation = "Ramp"
>>> keyf1.KeyTime = 0
>>> keyf1.KeyValues = [0,0.2,0]
>>> keyf2 = servermanager.animation.CompositeKeyFrame()
>>> keyf2.KeyTime = 1.0
>>> keyf2.KeyValues = [0,0.4,0]
>>> cue.KeyFrames = [keyf1,keyf2]
>>> movie.Play()

I'm pretty sure other people have this working, so it would be good to have
some pointers.

Cheers,

Adriano
