CS 4731 Computer Graphics, A term 2014

Course Details

The course CS 4731 Computer Graphics is offered in the A term of 2014.

Lectures

Lectures are held in FL-320, Monday through Thursday and Friday, from 4:00 to 4:50 PM.

Teaching Assistant and Instructor

The teaching assistant for the course is Mi Feng, and the instructor is Prof. Emmanuel Agu, who can be found in FL-139. Office hours for the instructor are Mondays from 2 to 3 PM, and other times by appointment.

Required Text

The required text for the course is Interactive Computer Graphics (6th edition) by Angel and Shreiner. It is important to note that the 6th edition is being used, not the 7th edition.

Supplemental Texts

Supplemental texts for the course include:

• OpenGL Programming Guide: The Official Guide to Learning OpenGL, Version 4.3 (8th Edition) by Dave Shreiner, Graham Sellers, John M. Kessenich, Bill M. Licea-Kane
• Computer Graphics using OpenGL (Third edition) by F.S. Hill Jr. and S Kelley
• OpenGL Shading Language (3rd edition) by Randy Rost and Bill Licea-Kane
• OpenGL SuperBible: Comprehensive Tutorial and Reference (6th Edition) by Graham Sellers, Richard S Wright, Nicholas Haemel

Facilities

Assignments should be done in C/C++ and can be developed on either Unix or Windows. However, the final executable must run on the Windows machines in the WPI Zoolab, with clear instructions in the documentation on how to run it.

Grade Policy

The grade policy for the course is as follows:

• 50% exams (2 exams)
• 50% assignments (4 projects)

Late Assignment Credit

Late programming assignments will be penalized 15 points off per day (per 24 hours). Assignments later than 4 days late will not be accepted.

Notes

Important notes for the course include:

1. Reading is mandatory, and working ahead is encouraged.
2. Exams shall be based on lectures, readings, and a bit of project knowledge, so class attendance is strongly encouraged.
3. Working and discussions in pairs are okay, but each student must turn in different and unique projects.
4. Cheating is strictly forbidden.
5. Cheating, defined as taking credit for work you did not do or knowledge you do not possess, is strictly forbidden. First offenders will receive a zero grade for the assignment or exam in question, and an academic dishonesty report will be filed with the Office of Student Affairs. Repeat offenders will receive an F for the course, and the case will be brought before the campus hearing board.
6. All assignments should be submitted electronically. Hard copies or submissions on disks will not be accepted. Both the executable and source code must be turned in. The documentation must include the structure of the project, what each file contains, and instructions for compiling and running the program.
