Course Information

The course CS 4731 Computer Graphics is offered in C Term 2013.

Lectures

Lectures are held in SL-411, Monday through Friday, from 2:00pm to 2:50pm.

Teaching Assistants

The teaching assistants for the course are:

• Hien Duong
• Satya Janga

Graduate Assistant

The graduate assistant for the course is Xuan Lu.

Instructor

The instructor for the course is Prof. Emmanuel Agu, located in FL-139. Office hours are Mondays from 4:00pm to 5:00pm, and by appointment.

Required Text

The required text for the course is "Interactive Computer Graphics" (6th edition) by Angel and Shreiner, published by Addison Wesley.

Supplemental Texts

Supplemental texts for the course include:

• "Computer Graphics using OpenGL" (Third edition) by F.S. Hill Jr. and S Kelley
• "OpenGL(R) Shading Language" (3rd edition) by Randy Rost and Bill Licea-Kane
• "OpenGL(R) SuperBible: Comprehensive Tutorial and Reference" (5th Edition) by Richard S. Wright, Benjamin Lipchak, and Nicholas Haemel
• "OpenGL Programming Guide: The Official Guide to Learning OpenGL, Versions 3.0 and 3.1" (7th Edition) by Dave Shreiner and The Khronos OpenGL ARB Working Group

Facilities

Assignments should be completed in C/C++ and may 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:

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

Late Assignment Credit

Late programming assignments will be penalized 15 percent 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 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 not done or knowledge not possessed, is strictly forbidden and will result in a zero grade for the assignment or exam and an academic dishonesty report.
6. Both the executable and source code must be turned in, with documentation that includes the structure of the project, what each file contains, and instructions for compiling and running the program.
