It is University policy that you read your official Drexel email; it is the course policy that you read it at least once per day.

Computer Graphics represents a vast technical field,
ranging from mathematics and geometry topics to computer hardware and
software engineering topics to rendering, animation and virtual
reality, far more than can be comprehensively covered in a 10 week
term. Computer Graphics I is designed to provide students with an
introduction to the fundamental algorithms of computer graphics
through detailed coverage of the mathematics and implementation of
2D and 3D line, curve and surface drawing. The
course culminates with a focus on 3D viewing
and visible surface algorithms.

Students are required to have taken CS260
(Data Structures), CS 350 (Software Design)
and Math 201 (Linear
Algebra). You will find this course extremely difficult if you do
not have strong (B or better) linear algebra skills. Minimal review of
linear algebra will be given in this class. Students are assumed to
have excellent knowledge of programming. Students can use whatever
programming language they wish (C, C++, Java, etc.) for the
assignments in this class with the following caveat: you will need to
turn in both source code and a makefile for testing and
evaluation. Code must run as a single
command-line process on the CS Department's Linux (tux) computers, or
possibly on a MacOS X computer, without needing special libraries.
Arguments passed to the
command-line will parameterize assignments; hence you'll need to
read command-line arguments (argc, argv) and parse input files. This
course is mathematically intense and implementationally challenging.
You will be required to implement complex data structures and
mathematical calculations as
a regular part of your assignments.

**Course Grading Scheme**

*I intend to use the standard grading scale of 100→ 90 (A), 89→ 80 (B),
79→ 70 (C), 69→ 60 (D), else (F).*

Also note that incompletes will not be given for this course.

**Assignments**

Link to Recorded Lectures

- Assignments (80%)
- Presentation (10%)
- Final exam (10%)

Also note that incompletes will not be given for this course.

Students __must__ work on the assignments __
individually__. No geometry or graphics libraries may be used in the
homework assignments.

**Presentation**

### Presentation Schedule

**Examinations**

**There will be a final exam on the material from class that is
NOT covered by the regular assignments.**

This includes the material presented by the graduate students.

### Final Exam Topics

1 point per day (max of 5 points) will be deducted
from late assignments.

You will be given a grade of **0** if an assignment is not
turned in by the last day of classes.

The programming assignments should be submitted on the class WebCT page before 11:59 PM on the due date.

*Note:* If the TA or instructor finds strong evidence of cheating
on assignments and/or the final examination, the student(s) involved
will receive an "F" in the course, and a memo describing the cheating
will be added to their student record. Be very careful, it is not
worth the risk.

*Note: *Your source code for all programming assignments will be
run through a plagiarism detection system. This program uses compiler
techniques, which are invariant of syntax and style. If you are
sharing/borrowing code with other classmates (from this or previous
years), you will get caught.

- Assignment 1 (Draw clipped lines) - Due October 9

- Assignment 2 (Sutherland-Hodgman polygon clipping) - Due October 23

- Assignment 3 (Draw clipped, filled polygons) - Due November 6

- Assignment 4 (Draw 3D lines) - Due November 20

- Assignment 5 (Z-buffer rendering) - Due December 4

- Extra Credit Assignment (Bezier curve drawing) - Due December 4

Every graduate student will make a 10 minute
presentation based on a research paper from the

SIGGRAPH Proceedings
or the
Seminal
Graphics Collection.

Students should choose a paper from 1998 or earlier on a subject that
will not be covered in class by Professor Breen.

If you are not on a drexel.edu computer you will have to access the papers through the Drexel Library by clicking on "ACM Digital Library" -> "Proceedings" -> "SIGGRAPH".

Online students will pick a paper and submit a Powerpoint presentation that describes the paper. There should be at least 10 slides in the presentation.
