What is CS155?

In CS155, we study the fundamental concepts and processes that drive 3D computer graphics. We begin with a study of digital images and digital image processing.  Next we study rendering techniques; rendering is the process by which a 3D model is converted to a 2D image.  We cover ray tracing and the graphics pipeline process.  Finally we look at some methods for modeling 3D objects including polygon meshes, spline curves and surfaces, and subdivision surfaces.

Projects

Your grade will be based on and four projects, labs, and class participation as described below.
15%     Image Processing project
25%     Ray Tracing project
20%     OpenGL project
30%     Final project
10%     Labs and class participation

Grades

Provided you meet the basic course requirement described in the following section, your grade will be assigned based on the percentage of possible points you receive as shown below:
A      96-100%
A- 91-95%
B+ 87-90%
B 84-86%
B- 81-83%
C+ 77-80%
C 74-76%
C- 71-73%
D+ 67-70%
D 64-66%

Basic Course Requirement

In order to pass the class you must earn a passing grade, as described above. In addition, however, you must meet the following basic requirement. Before the final exam time of the course, you must submit a solution to each programming assignment that successfully implements at least 50% of the assigned features. In other words, you cannot blow off an entire assignment and pass the class! Note that this basic requirement is necessary but not sufficient to pass the class. Note also that late penalties are used to calculate your grade but are not used with respect to this basic requirement.

Late Policy

You begin the semester with 5 one-day extensions that may be used to extend programming assignment deadlines. You earn an additional one-day extension each time you submit a programming assignment 24 (or more) hours before its due time. Assignment submitted after the due time plus extensions will lose points for each late day. Each project description includes the number of extension days that can be used for the assignment and its late day penalties.

Honor Code

We provide skeleton code for most of the assignments. Any additional code you submit must be designed and written by you unless you obtain prior approval from me. Any violation of this policy will result in (at least) course failure. If in doubt, ask.
