Animating Images

Image Animation is a continuous display of a sequence of frames obtained from a given image. Each frame represents the result displayed with a different amplitude. The frames follow each other rapidly giving the feeling of motion.

By animating a deformed geometry or a normal vibration mode, you can get a better insight of the behavior of the system. Sometimes, you gain a more thorough understanding of the system behavior.

This task shows how to Animate Images.

You can use the sample26.CATAnalysis document: you created a Stress Von Mises image.

Before You Begin:

	Go to `View -> Render Style -> Customize View` and make sure the `Materials` option is active in the Custom View Modes dialog box.
	Activate the Stress Von Mises image. For this, right click the `Von Mises Stress (nodal value)` feature from the specification tree and select the `Activate/DeActivate` option from the displayed contextual menu. A warning appears to let you know that the solution needs to be updated. Click `OK` in the warning box.

1. Click the Animate icon .
The image is animated with default animation parameters and the Animation dialog box is displayed. You access any point of the simulation at random.

2. Click the Pause button .
The animation is interrupted.

3. You can now change the animation parameters to the desired values:

	Define the Loop mode: Play once in one shot Repeat play non stop Repeat play and reverse non stop
	Play: Jump to start Plays backward Steps backward Pause Steps forward Plays forward Jump to end
	`Steps Number`: To make the animation more or less fluent
	`Speed:`To manually define the desired speed

For a smooth animation set the Number of steps parameter to its maximum value (20) and activate the Repeat play and reverse non stop button .

4. Click the Play Forward button .
Animation is resumed, with the new settings taken into account.

5. If needed, modify the Steps Numberand click the More button.

Both the the dialog box and the model appear as shown here:

use non symmetrical animation (default value)

use symmetrical animation

	`All occurrences`: animate all the modes of the Frequency case. When activated, this option allows you to choose whether you want to `Memorize frames:` the frame animation will be speed driven but memory consuming. If you do not activate the `Memorize frames`option, the frame animation will need less memory but will be slower.
	`One occurrence`: animate the selected Frequency case.

	`Interpolate values`: in the case of non symmetrical animation, animate the interpolated values of the activated image.
	`Interpolate displacements`: animate the interpolated displacements of the activated image.

If you select the symmetrical animation button , both the dialog box and the model appear as shown here:

6. Click Close to leave the Animate Window dialog box and thereby exit the Animation application.

The animation capability is also available for Frequency Solutions.
