The Critique

In groups of three or four, each person is to present their bouncing ball movies.

The group as a whole then selects three movies or projects which illustrate quotes from:

John Lasseters' "Principles of Traditional Animation Applied to 3D Computer Animation"

The group will then present each selection to the entire class and read the quote that most applies to the bouncing ball animation.

THE BOTTOM LINE:

You must read the article and connect a pertinent idea to each animation you show.

3 animations = 3 quotes

 

Due: 2nd Class (Thursday) Week 02, at the beginning of class.

To Turn In:

          1. Your 3DS Max 2010 file -- (it must work on the school machines)
          2. A rendered QuickTime movie CLEARLY showing your balls bouncing, one at a time, down the stairs and into the cage.
          3. All of the above in a folder labeled: "Lastname_Firstname_BBalls".

Read the pdf handout: "Timing for Animation: Bouncing Ball"available on the Drop Off Drive.

Next class we will critique your work based on that reading.

Instructions:

You are to bounce three balls, one at a time, down the stairs and into the arena.

The balls are each of a different type:

1. A basketball

2. A bowling ball

3. A non-helium-or-hydrogen-filled balloon .

You are to animate each falling down the stairs with realistic, true-to-physics timing, squash and stretch, and arcs.

You may add another ball composed of the material of your choice once you have completed these.

Script:
The ball rolls down, drops, and bounces toward the box. The ball interacts with the box and heads toward the other objects. .
 
Grading: will be based on how successful you were at demonstrating the following:
  1. How believable is your animation? (Does that sphere move like a basketball or a bowling ball?) Make your animation look “correct” in normal, slow, and reverse speeds.
  2. Does each object that is moving move in an appropriate (believable) manner?
  3. How does a bowling ball move differently from a basketball?
  4. How different is their timing from one another?
  5. How appropriate are the interactions between objects (stationary and movable)?
  6. How does the volume of the sphere change as it interacts with other objects?
This Assignment: will address the following course competencies:
  • Identify the fundamental animation features and function devices in the 3D animation software package used
  • Transform a 3D model using motion and time
Web resources: Feel free to use these for reference.
