Driven Diagrams
Animation
If the model has variables defined by functions or actions, then it is possible to obtain a special type of a
diagram – “driven”. Since the values of such variables are dependent values, the system creates their
diagrams automatically. The lines corresponding to the dependent variables in the list of the animation
screenplay dialog box are grayed out. A “driven” diagram cannot be edited; it merely illustrates the variation
of the variable during an animation. Note that a driven diagram is regenerated upon starting an animation.
This type of a diagram can be used for analyzing mutual positions of various model elements. A variable can
be created for this purpose, whose value would be the function of the distance measured between two bodies,
vertices, etc. When modifying the model parameters, the diagram of such a variable will reflect changes in
the distance concerned.
General Animation Parameters
Besides the described above, a number of options are available in the toolbar and under the “Edit” menu
entry.
Set Limits For Time Scale
This option sets the limits of the Time axis portion visible in the diagram pane.
Change Current Screenplay Name
This option allows saving the current screenplay under a different name and/or change the color of the
outlining frame highlighting the active diagram window (the parameter “Active window color”).
Save Active Diagram To Text File
This option allows saving the current diagram or the selected nodes in a text file (*.tfg). In future, the file
contents can be inserted into another diagram or another screenplay.
Update List Of Variables For The Current Model
This option reloads the changes in the model variable list.
+ Set Parameters For.avi File
This option allows defining the parameters for recording an .avi file. The parameters are the same as the
respective ones in the command “AN: Animate Model”.
+ Set Limits, Step And Delay For Playing Animation
This option defines the values of the following parameters:
Start time, Т. Defines the time instant from which the animation should begin.
End time, Т. Defines the time instant at which animation ends.
