Allows the user to preview animation scripts in MGED. The -d option provides a delay in seconds to be applied between each frame (the default is no delay). The -D option allows the user to specify a starting frame number, and the -K option allows the specification of an ending frame number. The -v flag indicates that the objects displayed in the MGED graphics window should be displayed in evaluated mode, as would be the result of the ev command. Note that this may significantly slow the preview.
The example shows the use of the preview command to preview specified frames of an animation script.
Example 1. Preview an animation script.
preview -D 101 -K 237 script.rt
Displays the animation script stored in the file named script.rt from frame number 101 through frame number 237.
