Workshop

 < Day Day Up > 

The Workshop consists of quiz questions and answers to help you solidify your understanding of the material covered in this hour. You should try to answer the questions before checking the answers.

Quiz

1:

When you stretched the circle using the vertical scale, why did you also compress the horizontal scale?

  1. You can't scale a symbol in just one dimension.

  2. It seemed like it would look cool.

  3. In real life, compressing a ball in one dimension will cause it to expand in the other direction the total volume of the ball never changes.

2:

Why did you add extra reverberation to the circle during the overkill task ("Use Overkill to Make an Animation More Effective")?

  1. It seemed like it would look cool.

  2. Real balls always exhibit this behavior.

  3. You wanted the ball to act as the user expects.

3:

Is it dishonest to use just a few keyframes instead of a long tween?

  1. Yes. It's not accurately demonstrating the physical movement you're animating and may open you to lawsuits.

  2. Maybe. But if the effect is a believable animation, you've succeeded.

  3. No. In real life, motion involves only two key points: the beginning and the end.

Quiz Answers

A1:

C. Although it might not be noticeable if you forgo this touch, you might be surprised when you can't figure out why something just doesn't look right. Take a rubber ball and push it on the ground. You'll see it get wider as you reduce its height. By the way, if while using the Transform tool you hold Alt when scaling, you can scale just one side.

A2:

C. Certainly you shouldn't do something just to make it look cool unless it adds to your message. A real ball might not settle in such a dramatic way, but the user understands the message, and it looks realistic.

A3:

B. You're not creating animations in order to show physical principles accurately, but to communicate ideas. Remember it's the result, not how you got to it.

Exercise

Here's a great exercise that I promise will help you become a better animator. Go to the library or video store and rent some classic animated movies to study. If you have a DVD player, you can easily step frame-by-frame through key animated portions. It's really educational.

For something more specific, start with a bouncing ball animation (either a ball bouncing repeatedly or across the screen). Add an ellipse-shaped movie clip to a new layer. Make that shape behave like a shadow literally shadowing the ball's movement. It should get bigger, darker, and sharper (via a Blur filter) as the ball gets closer, and get smaller, lighter, and blurrier as the ball goes up. Compare the results before and after adding the shadow; the differences should be striking.
