2.1.2 Using the Time Animation Widget
- Click on the dropdown box on the left side of the widget to
see the list of times that are in this display. It will
look something like this.
- Select the third time in the list to view the visualization for
that time step.
- Loop through the entire animation by clicking the
button on the animation widget.
- Stop the animation by clicking the
button.
- Return to the first time step by clicking the
button.
- Step forward through the animation one step at a time by
repeatedly clicking the button.
- Step backward through the animation one step at a time by
repeatedly clicking the button.
- Go to the last time step by clicking the
button.
- The row of boxes at the top of the widget
is a visual indicator
of the current position in the animation sequence.
Click on a box to go to that point in the sequence.
- You can also use the boxes to skip particular timesteps. If you
right click (MB3) on a box, it will turn red indicating that
that step will be skipped. Right click on a box and then
start the animation to see that the timestep is skipped.
- Open the
Time Animation Properties
editor
by clicking the button.
- Change
Direction
to rock back and
forth by selecting the Rocking
option from
the dropdown list and then click the Apply
button.
- Start the animation. When the loop reaches the last time step,
the animation steps backward. When it reaches the first time,
it goes forward again.
- Set the
First dwell
to be the same value as the Last dwell
,
and then click the Apply
button to
see the effect.
- Set the
Direction
back to Forward
.
You can also define your own time animation under the
Define Animation Times
tab. We'll look at that in
a later exercise.
