7 \n In \b Post-Pro module you can generate real-time animation of
8 fields. In comparison with sweeping, animations are created on the
9 base of frames, displaying field presentations generated on \b EVERY
10 timestamp of your field. So, the frame displaying the field
11 presentation created on the base of the first timestamp will begin
12 your animation and the frame displaying the field presentation created
13 on the base of the last timestamp will end it. In sweeping <b>ONLY
14 ONE</b> timestamp is used for its generation.
16 In the case of animation of several fields <b>Parallel Animation</b>
17 will display the animations simultaneously, while <b>Successive
18 Animation</b> will display them one after another.
19 \n In the case of <b>Parallel Animation</b> you can set different
20 kinds of presentations for each of the selected fields. This animation
21 type also requires that the number of timestamps > 1 and is the same
22 for all animated fields.
23 \n For <b>Successive Aimation</b> the kind of presentation should be
24 the same for all selected fields, which means that it is not possible
25 to select a field from the list. It is also necessary that the number
26 of timestamps > 0 and the number of components is the same for all
29 \ref slider_page functionality also allows to create real-time
30 animation on every time stamp of the field. This is another,
31 somewhat more user-friendly, implementation of animation on fields.
33 <em>To generate an Animation:</em>
36 <li>Right-click on the field in the Object Browser.</li>
38 <li>From the pop-up menu select \b Parallel or <b>Successive
40 The following dialog box will appear:
42 \image html animation.png
44 \b Animation dialog box is destined for management of your animation.
46 <li>Click <b>Setup Animation</b> button. The following dialog box
47 allowing to set the parameters of your animation will appear.
49 \image html setupanimation1.png
51 – <b>Use range of time stamps</b> check box allows to select the range
52 of time stamps, which will be used for generating your animation.
54 \image html setupanimation2.png
56 – <b>Use sequence of time stamps</b> check box allows to select
57 the time stamps, which will be used for generating your presentation
58 from the list of time stamps
60 – \b Fields: list of fields for animation.
62 – \b Properties: Here you can adjust properties of each field
63 selected from the list:
65 <li>Select the \b type of field presentations, which will be used as
66 frames in animation.</li>
67 <li>Set properties of the <b>Scalar Bar</b> (\ref scalar_map_page "see also").</li>
68 <li>Adjust additional \b properties of the selected type of field presentation.</li>
72 <li>Click \b OK to validate your parameters. You will return back to
73 \b Animation dialog box.</li>
75 <li>Click <b>Generate frames</b> button to generate the frames for
76 your animation based on the parameters adjusted in <b>Setup
77 Animation</b> dialog box.</li>
80 <br><em>Running animations:</em>
82 In the main \b Animation dialog box there are several button intended
83 for management and running your animation:
86 <center><b>Running</b> your animation</center>
88 \image html previous.jpg
89 <center><b>Previous</b> frame (time step)</center>
92 <center><b>Next</b> frame (time step)</center>
94 \image html begining.jpg
95 <center><b>To the beginning</b> of the animation.</center>
98 <center><b>To the end</b> of the animation.</center>
100 <br><em>Additional options of the animation:</em>
102 You can <b>increase/decrease</b> the speed of your animation by moving
103 the \b Speed wheel \b Up/Down:
105 \image html speed.jpg
108 <b>Cycled animation</b> check box: this option allows to start a
109 cycled animation of your presentation.
111 <b>Use proportional timing</b> check box: this option allows to render
112 your animation with proportional periods of time between every frame
113 (not depending on the time stamps).
115 <b>Clean memory at each frame</b> - this option allows to optimize the
116 performance of the operation.
118 \note <b>Save animation to AVI file</b> works only if there is \b
119 jpeg2yuv utility installed on your computer. If this third-party
120 product is missing, the check-box will not be selectable. This utility
121 is a part of \b mjpegtool package, which can be downloaded from
122 http://mjpeg.sourceforge.net/. Run "which jpeg2yuv" to check whether
123 this tool has been installed and the path to it was properly added to
124 your PATH variable. If not, you need to activate \b mjpegtools
125 indicating its location in the variable PATH. The syntax of the
126 command should be as follows: export
127 PATH=${INSTALL_ROOT}/mjpegtools-1.8.0/bin:${PATH}.
130 <b>Save Animation</b> - saves changes made in the published
131 animation. If you have already published a study and press <b>Publish
132 to study</b> again you get another animation in the Object Browser.
134 <b>Publish to Study</b> - saves your animation in the study and
135 presents it in the Object Browser.
