Animating time series
Server Manager has a complicated animation engine based on keyframes and scenes. This section will introduce a few simple ways of animating your visualization. If you have a time-aware reader, you can animate it with AnimateReader().
reader = ExodusIIReader(“.../can.ex2”) Show(reader) Render() c = GetActiveCamera() c.Elevation(95) # Animate over all time steps. Note that we are not passing the optional # 3rd argument here. If you pass a filename as the 3rd argument, # AnimateReader will create a movie. AnimateReader(reader) # Save the animation to an avi file AnimateReader(reader, filename=".../movie.avi")
Animating properties
To animate properties other than time, you can use regular keyframes.
Sphere() Show() Render() # Create an animation scene scene = servermanager.animation.AnimationScene() # Add one view scene.ViewModules = [GetActiveView()] # Create a cue to animate the StartTheta property cue = servermanager.animation.KeyFrameAnimationCue() cue.AnimatedProxy = GetActiveSource() cue.AnimatedPropertyName = "StartTheta" # Add it to the scene's cues scene.Cues = [cue] # Create 2 keyframes for the StartTheta track keyf0 = servermanager.animation.CompositeKeyFrame() keyf0.Interpolation = 'Ramp' # At time = 0, value = 0 keyf0.KeyTime = 0 keyf0.KeyValues= [0] keyf1 = servermanager.animation.CompositeKeyFrame() # At time = 1.0, value = 200 keyf1.KeyTime = 1.0 keyf1.KeyValues= [200] # Add keyframes. cue.KeyFrames = [keyf0, keyf1] scene.Play() # Some properties you can change # # Number of frames used in Sequence mode # scene.NumberOfFrames = 100 # # Or you can use real time mode # scene.PlayMode = 'Real Time' # scene.Duration = 20
