| == Animating time series == | | == 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.
| | {{ParaView/Template/DeprecatedUsersGuide}} |
| If you have a time-aware reader, you can animate it with AnimateReader().
| | {{ParaView/Template/Footer}} |
| | |
| <source lang="python">
| |
| 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")
| |
| </source>
| |
| | |
| == Animating properties ==
| |
| To animate properties other than time, you can use regular keyframes.
| |
| | |
| <source lang="python">
| |
| 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
