CS 3451 - Computer Graphics
CS 3451 - Computer Graphics is a 3 credit hour course that introduces students to fundamental concepts in digital image generation and manipulation. Processing is used to code projects. No prior knowledge of computer graphics is expected.
Computer Graphics is a required course for the Media thread. Most electives for the Media thread require CS 3451 as a prerequisite.
Workload
Grades in this course are heavily weighted toward individual projects. These projects require the student to implement a core concept in graphics.
Below is a list of projects assigned by Dr. Greg Turk for his Spring 2022 course:
- 1A - Transformation Matrices
- 1B - Projection and Line Drawing
- 2A - Object Modeling
- 2B - Animation
- 3A - Ray Tracing Cylinders
- 3B - Spheres, Shadows, and Reflections
- 4 - GPU Programming
- 5 - Dual Meshes
Aside from the projects, there is also a midterm and a final exam.

Class Structure
CS 3451 holds three 50-minute lectures a week. Office hours are available for assistance with project implementation.
Prerequisite Knowledge
No prior experience in computer graphics is expected for students taking CS 3451. Coding for most projects is done in Processing (p5.js), and GPU programming is done in GLSL (OpenGL Shading Language). Time is spent during lectures to introduce students to these languages.
Formal prerequisites for the course are CS 1332, CS 2340, CS 2110 (or an equivalent low-level programming course), and MATH 2551 (or an equivalent Calc III course).
CS 1332 - Data Structures and Algorithms
Programming projects will involve implementation of data structures and algorithms discussed conceptually in class, such as polyhedral structures and ray tracing algorithms.
CS 2340 - Objects and Design
While Objects and Design is a formal prerequisite, nothing from CS 2340 is necessary for success in CS 3451.
CS 2110 - Computer Organization and Programming (or equivalent)
Topics such as the Graphics Hardware Pipeline and GPU programming assume familiarity with computer organization and programming.
MATH 2551 - Multivariable Calculus (or equivalent)
Common tasks will involve the three-dimensional manipulation of objects, rays, and cameras through code. Matrix transformations are used frequently throughout the entirety of the class.
Scheduling
This course is required for students pursuing the Media thread. Because CS 3451 is heavy with prerequisites, students should not expect to take this course until their junior or senior years. One should take into consideration that most Media thread electives require a passing grade in CS 3451.
