Here is an updated version of your script with inline comments. That
should get you started.
-----------------------
from paraview.simple import *
# Create a view first!!!
CreateRenderView()
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=[]
# the time for the animation cue are in relation to the StartTime and EndTime
# for the scene which by default is 0.0 and 1.0 respectively, so we scale the
# KeyTime values for key frames accordingly
ts=1.0/len(pts)
for i in range(len(pts)):
# Create the sphere
spheres.append(Sphere(Center=pts[i], Radius=2,ThetaResolution=5))
repr = Show(spheres[i])
repr.DiffuseColor=[0.5,0.8,0]
# Animate
cues.append(servermanager.animation.KeyFrameAnimationCue())
# Visibility is a property on the representation, not the sphere itself.
cues[i].AnimatedProxy = repr
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]
# Doing this here so that the camera is setup correctly to view all the spheres
ResetCamera()
scene.Cues = cues
# set the number of frames in the animation.
scene.NumberOfFrames = 100
scene.PlayMode = "Sequence"
scene.Play()
