Part 3: Process book. In your local working area (e.g., a hard disc drive of your home computer, in your account on the ATEC server, your USB memory stick connected to a computer in an ATEC lab, etc.), create a process book page for Assignment 2 in the html format. You can use Microsoft Word, DreamWeaver, or any application you like. The main page should be named as processbook.htm (not processbook.html -- the extension should be "htm" not "html".).

Your process book 's main page should have links to all the required elements specified above (i.e., a reference video and path of action drawing with timing.).

Submission:

1. Log onto one of the machines in the ATEC building.
   
2. Go to the folder in \\Atec01\Midori\Drop Box\4337\your last name.
   
3. Create a new folder in the folder with your last name and rename it at A2.
4. Copy your process book's main page, processbook.htm, and any other files that are linked to the main page into your folder A2.
   

Requirements:

• Transfer your files to the specified folder before the class starts.
• Your process book must be accessible from your name (link) in "student_works.htm" in \\Atec01\Midori\Drop Box\4337.
• Your process book 's main page should have links to all the required elements specified above and the links must be made among the files in the specified folder, i.e., no links should point back to your local area. Make sure the links work before the class starts.
  

Produce a playblast (or hardware rendered) animation with two bouncing balls (i.e. two balls should be animated in one animation) to contrast the behaviors of the two. In order to apply squash and rotation properly, read order of transformation again.

Requirements:

• The animation should contain a complete thought on each ball. This means each ball's motion is followed through, i.e., each ball should be animated until it comes to a complete stop or is carried off the screen (i.e., the ball exits screen). The animation should not end abruptly.
• Vertical movement (y-translation) and horizontal movements (x- and/or z-translation) of each ball are required.
• Animate at least 120 frames.
• Use half frame size, 320 x 240.
• The heights of a ball's bounces should decrease gradually over time.
• The amounts of time that a ball's bounces take should decrease gradually over time.
• The amounts of squash should decrease gradually over time.
• In the key frame for the moment when the ball bounces off the surface (i.e., when the ball is in contact with the surface), “break tangents" in the Graph Editor to make the curve a “V” shape, instead of adding more keys or leaving the curve in a "U" shape.
• Squash and rotation are required.
• For each squash, the attributes related to the squash must have keys in three frames: a) in one frame before the key in that the ball is in contact with the surface; b) in the frame in that the ball is in contact with the surface, c) in one frame (or two frames) after the key in that the ball is in contact with the surface. In this manner, each squash happens in two or three frames: A squash starts in a); The squash is at its extreme in b); The squash ends in c).
• If you apply squash using scaling factors, the ball must be scaled up along the x- and z-axes and scaled down along the y-axis for each squash. In order to apply squash (scaling) and rotation properly, use a proper hierarchy for transform nodes. (See order of transformation.)
• If you apply squash with a squash deformer, put the deformer in the ball's hierarchy so that it moves properly with the ball.
• Transfer your files to the specified folder, and make sure the links work and the animation file is playable before the class starts on the due date.
• If you really want to, you can render your animation using software renderer, but this assignment is about animation and you need to focus on animating.
• Among the principles of animation, squash, follow through, arcs, and timing are required. (Apply other principles, such as anticipation, staging, and exaggeration, for extra credits.)

Submission:

1. Submit the following files into \\Atec01\Midori\Drop Box\4337\your_last_name\A2

• Scene file (Maya binary file).
• Screen capture each ball's x-, y-, and z-translation channels in Maya's Graph Editor.
• Screen capture each ball's x-, y-, and z-scaling channels (or squash deformer's factor channel if you use a squash deformer for squashes, instead of scaling) in Maya's Graph Editor. (The graphs should be scaled appropriately and readable.)
• AVI animation (10 mb or less).

2. Create links from your process book's main page to files above and make sure that the links work..

• Your assignment should be at least 50% done by the work in progress presentation date. Have the work in progress's scene file and AVI animation in the process book before the class starts.
• Have the final version of scene file, screen captures, and AVI animation in the process book before the class starts on the assignment due date. Do not replace the work in progress's scene file and AVI animation with the final version's but add the final version's scene file, screen captures, and AVI animation to your process book.
• Do not save any files other than the ones you are required to submit in the class's submission folder. \Atec01\Midori\Drop Box\4337\ is not a work space.
