Instructions for CSC012N Laboratory of 20 November 2001

This is a special group programming assignment. It begins with a group programming laboratory on 11/20. Normally you must do your own work. For the laboratory, you are expected to work in groups of 3-5 persons. The groups have been pre-arranged. If the absence of some students forces a group below 3 persons, the remaining 1-2 persons may join another group, but no group is to consist of fewer than 2 persons, nor more than 6 persons. You must accurately report who has worked on each project. It is acceptable for individuals to help another group, but all such contributions of effort must be accurately reported.

For the laboratory, each group is to work on producing one of three animation applets. The list of three acceptable applet projects is:

• A simple animation of a head with the left eye winking, while the right eye shifts side-to-side. Make the head as realistic as you can.
• A colorful cartoon of a steam railroad engine rolling smoothly along a track from the left to the right side of the screen. As the engine rolls it is to emit puffs of smoke.
• An animation in which a ball rolls along a shrinking spiral from the outside of the image towards the center, changing color gradually from pure red to pure blue.

Each animation must be able to be resized when run with appletviewer. Each animation must repeat without manual intervention.

At the end of the lab each group should email the best .java file for their applet to yaya@dowling.edu. This applet will be graded.

After the laboratory is done, the members of the group have until the due date of the assignment to improve their result collectively or individually and then to send an improved applet .java file to the instructor. In addition, each group or individual is to prepare a short discussion of the data structures and methods that would be useful in a java class for animation, and email that discussion as well. There will be a grade for the final applet and a grade for the essay. If no final applet is submitted, your laboratory group grade will be recorded a second time as your final applet grade. It is up to each person to decide for themselves if they wish to submit the final applet or the essay for grading as part of a group to be graded collectively or as an individual to be graded individually, but an accurate history of the contributions of all parties must be included in either case. If you wish to have extra credit, you may work on one or both of the other animations and submit that by 12/4.
