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