CS 381 Fall 2012
Assignment 7

Assignment 7 is due at 5 p.m. Tuesday, December 11. It is worth 20 points.

Procedures

E-mail answers to the exercises below to ggchappell@alaska.edu, using the subject “GA7”.

• Your answers should consist of the source code for the web page and any associate program(s), as required by Exercise A, or a single archive file (ZIP?) containing these. These should be attached to your e-mail message.
• Send only the above! I do not want project files or executables. I also do not want things I already have, like glut.h.
• Be sure to include your name in your e-mail.
• I may not read your homework e-mail immediately. If you wish to discuss the assignment (or anything else) with me, send me a separate message with a different subject line.

Working in Pairs

This assignment may optionally be done in pairs. If you work with someone else:

• Put both names in the submission e-mail and in the source code files.
• Cc: the submission e-mail to the other student, so that I can send an acknowledgement to both.
• Under normal circumstances, both authors will receive the same grade.

Exercises (20 pts total)

Exercise A — Web Page with Canvas

Purpose

In this exercise, you will create a web page with a canvas element containing programatically generated graphics.

Instructions

Write an HTML5 web page and associated program code (most likely either JavaScript or Processing) that meet the following requirements.

• Your web page must include at least one canvas element that displays graphical content that is both nontrivial and original.
• The content must change somehow: either with time, or in response to user actions.

Notes

• Yes, this assignment is very open-ended.
• Your program code may be included in your HTML file or in a separate file; do as you think best.
• I have processing.js; if you use it, you do not need to send me the source for the compiler.
• Most of the requirements for previous assignments (OpenGL, rules for callbacks, etc.) do not apply here.
• However, general standards for code are as for the first assignment (must compile, readable, following conventions, avoid extra output, clear how program is used, not buggy-looking, give credit, etc.).
