[Paraview] Visibility Animation using Python Batches

[Maxime Taquet]

Dear all,

Sorry if this question sounds dummy but I'm really new to Paraview and Python. I would like to realize and save an animation that displays tens of sphere sequentially (i.e. the spheres appear one at a time). Since I have a lot of them, I would like to do it using Python commands. However, it does not seem to work at all for me. Here is what I tried:

scene = servermanager.animation.AnimationScene()
scene.ViewModules = [GetActiveView()]
pts = [[15,15,15],[10,10,10],[5,5,5],[0,0,0],[-5,-5,-5],[-10,-10,-10],[-15,-15,-15]]
spheres=[]
cues=[]
ts=1
for i in range(len(pts)):
	# Create the sphere
	spheres.append(Sphere(Center=pts[i], Radius=2,ThetaResolution=5))
	Show(spheres[i])
	r = GetRepresentation()
	r.DiffuseColor=[0.5,0.8,0]
	# Animate
	cues.append(servermanager.animation.KeyFrameAnimationCue())
	cues[i].AnimatedProxy = GetActiveSource()
	cues[i].AnimatedPropertyName = "Visibility"
	keyf0 = servermanager.animation.CompositeKeyFrame()
	keyf0.KeyTime = 0
	keyf0.KeyValues=0
	keyf1 = servermanager.animation.CompositeKeyFrame()
	keyf1.KeyTime=i*ts
	keyf1.KeyValues=1
	cues[i].KeyFrames=[keyf0,keyf1]

scene.Cues = cues
scene.Play()

and I get this error:

ERROR: In /Users/partyd/Dashboards/MyTests/ParaView-3-8-0/ParaView3/Servers/ServerManager/vtkSMBooleanKeyFrameProxy.cxx, line 48
vtkSMBooleanKeyFrameProxy (0x143059ee0): Cue does not have domain or property set!


If there's a simple GUI way to do it, I'd be blessed too of course but I don't want to do it for each point separately. In the example, above, I just set pts to some arbitrary values but in my case I really have tens of points.

Thank you a lot in advance!
