12 Animate is an interactive animation tool specifically designed to be
13 used with Geomview. It provides several simple animation controls such
14 as looping, bouncing, and single frame stepping, as well as adjustable
15 speed playing. The program works by telling geomview to read in a
16 sequence of geomview files and then telling geomview to display each
17 frame of the sequence in order.
18 There are two methods that Animate provides for specifying which frames
20 one wants to have in the sequence being viewed. The first method is to
21 enter the name of every frame into the text input box and press return
22 or click on load. The name of each frame must correspond with the name
23 of a geomview file existing in the file system.

26 pict1 pict2 pict3 pict4
28 pict*
29 pic??
30 The second method of loading frames is to first create an animation
32 script file outside of animate and then load the script in by typing
33 its name in the input box and clicking on the script button. The advan‐
34 tage of this method is that you can more easily specify the exact order
35 in which you want the frames to be shown. The format of the script file
36 is a list of frame names each followed by a newline. Comments prepended
37 by a # sign are allowed.
38 EXAMPLE SCRIPT FILE
40 # list of frames for
42 # my rotating cube movie
43 cube.02
44 cube.04
45 cube.03 # get rid of this frame later
46 cube.01

51 Loading frames into memory may take a little time, especially if each
54 frame is a particularly large file. Be sure the machine you're using
55 has sufficient memory to load all the frames you desire. Once all
56 frames have been loaded, an 'animate' object will appear in the
57 geomview object browser. It is now possible to begin animating.
58 Scrolling through frames can be accomplished in several different ways.
60 The first, and most obvious way is by 'playing' the frames. Clicking on
61 the Play button causes animate to begin playing through the frames in
62 order, starting with the first frame or whichever frame has been
63 selected. The corresponding name of each frame being shown is shown in
64 the pink text-entry box. Click on Stop to cease playing.
65 Animation speed depends on the size and complexity of the object in
67 each frame. Thus different sequences can have considerably different
68 top playing speeds. Use the Speed slider to set an upper limit to the
69 animation rate. You can also play slowly through the frames can also
70 by clicking repeatedly on either step button.
71 Press the Bounce button to enter bounce mode. While in bounce mode,
73 direction of play reverses whenever the first or last frame is reached.
74 Clicking on either Step button determines the playing direction.
75 Clicking on Once puts animate in 'once' mode. While in this mode, upon
77 reaching the first or last frame (depending on which direction you are
78 going) of a specified sequence, animate will stop playing. Normal
79 playing can be resumed by clicking on Once again to exit this mode.
80 The Info button will bring up a short menu containing helpful hints for
82 program usage. Clicking on the exit button will cause the program to
83 exit.
84
86 -p Start playing through the frames right away upon startup.
87 -b Go into bounce mode upon startup.
89 -s speed
91 Set the speed of play upon startup. The value of speed may be an
92 integer between 0 and 100 which roughly signifies the percentage
93 of top playing speed.
94 -o Set animation to play through only once upon startup.
96 -S script
98 Specify name of script containing filenames for objects to be
99 read in upon startup. Takes precedence over -f option if
100 present.
101 -hide Makes animate invisible upon startup. *Warning* all animate com‐
103 mands must be specified on the command line when this option is
104 used since there is no way to access the main window.
105 -f file1 file2 ...
107 Specify names of files containing objects to be read in upon
108 startup.

111 When loading sequences one after another, geomview will often not load
112 a sequence on the first try. This can often be remedied by telling ani‐
113 mate to load the sequence yet again.
