Madalena,
The time units in ParaView can be anything you want them to be: minutes, seconds, \
epochs, jiffies, whatever. ParaView does not manage the units for time; it is an \
exercise for the user to ensure that all time values refer to the same scale (and \
bias).
You can control the time range (the time values where the animation starts and stops) \
through the animation scene object returned from GetAnimationScene(). The StartTime \
and EndTime fields can be set to the start and end times you want your animation to \
be. The following code sets the animation range to be compatible with the keyframe \
times you describe below.
# get animation scene
animationScene1 = GetAnimationScene()
# Properties modified on animationScene1
animationScene1.StartTime = 1.0
animationScene1.EndTime = 3.0
If you want to control the playback of the animation in terms of frames or speed, you \
can do so with the PlayMode and other parameters. For example, in the email below you \
mentioned the time value in terms of minutes. If you wanted you keyframes to play \
over the course of 2 minutes (the time between T = 1min and T = 3min is 2 minutes), \
you can set the PlayMode to 'Real Time' and set the Duration field to 120. (The \
duration is measured in seconds, so 2 minutes converts to 120 seconds.) You can do \
that as follows:
animationScene1.PlayMode = 'Real Time'
animationScene1.Duration = 120
Alternately, you can request a certain number of frames in the animation. You cannot \
specify arbitrary time values for every frame, ParaView evenly spaces them between \
the start and end time. But if your keyframes are evenly spaced it is easy to align \
them. So if you want a frame at every keyframe in the example below, you can use the \
following code.
animationScene1.PlayMode = 'Sequence'
animationScene1.NumberOfFrames = 3
In the GUI, all of these controls are in the Animation View widget. You can learn \
more about the animation view in the ParaView tutorial \
(http://www.paraview.org/Wiki/The_ParaView_Tutorial), specifically in Exercise 2.18. \
These tools are also documented in the ParaView User's Guide \
(http://www.paraview.org/paraview-downloads/download.php?submit=Download&version=v4.3&type=data&os=all&downloadFile=TheParaViewGuide-v4.3-CC-Edition.pdf), \
specifically in Section 7.2. Once you know how to set these controls in the GUI, you \
can use ParaView script trace to learn the appropriate Python commands.

Subject: [EXTERNAL] Animate a solid with a specific time serie
Deal all,
I want to animate a solid that moves acording to specific time serie (time, \
position). By recording the code via python shell i see that appears two simple \
keywords that moves the solid by proving specific values.
example:
# get animation track
box1CenterTrack = GetAnimationTrack('Center', index=0, proxy=box1)
# create keyframes for animation track
keyFrame0 = CompositeKeyFrame()
keyFrame0.KeyTime = 0.0
keyFrame0.KeyValues = 60.0
keyFrame1 = CompositeKeyFrame()
keyFrame1.KeyTime = 1.0
keyFrame1.KeyValues = 0.0
# initialize the animation track
box1CenterTrack.KeyFrames = [keyFrame0, keyFrame1]
My doubt is the place where is possible to provide my time serie of time and \
position. And what is the time units of KeyTime? The KeyValues is position if i \
understand the sample that i run.
Instead a specific time serie it is possible to provide each line of time serie as \
KeyTime and Kay Value, and then for the animation track call them all.
Example:
time (minuts) position (m)
1 7.2 Converted in script: keyFrame1.KeyTime = 1.0; \
keyFrame1.KeyValues = 7.2 2 9.374 Converted in script: \
keyFrame2.KeyTime = 2.0; keyFrame2.KeyValues = 9.374 3 11.548 Converted \
in script: keyFrame1.KeyTime = 3.0; keyFrame1.KeyValues = 11.548
\
box1CenterTrack.KeyFrames = [keyFrame0, keyFrame1, KeyFrame 3 etc..]
Is possible to do sometinh like that? Convert my time serie of time and position to \
each keytime and keyvalues in script?
Kind regards
Madalena
