## Overview

Interactive Computer Graphics is about the techniques and technologies used to generate synthetic digital imagery in real-time. The main focus of the course will be 3D photorealistic rendering and the current, practical rendering methods used in games and other applications.

The topics we will cover include:

- Geoemetric modeling
- Mathematics for animation and rendering
- Shading and programmable shaders
- Rasterization
- Physics simulation
- Global illumination

We will learn how to implement 3D web applications using WebGL and JavaScript. WebGL shares many of the same characteristics as Vulkan, Direct3D, and other popular low-level graphics APIs, so the skills you learn should be transferable.

## Office Hours

**Every Thursday at 11am on ZOOM**

## Prerequisites

We recommend the following courses and skills:

- CS 225 - prior general programming experience
- Math 225 or Math 415 - basic linear algebra, especially 3D transforms

## Lectures

Lecture is held in 1310 DCL on Tu Th 11-12:15

## Discussion Sections

We will not use discussion sections this semester…you only need to attend lecture.

## Programming Assignments

There will a series of four programming assignments. See the Assignments page for more details.

## In-Class Work (or Homework)

Starting in Week 2 of the semester, each (or almost each) lecture will include in-class exercises. These exercises will be available online using the PrairieLearn system. You should bring a phone or laptop or tablet to lecture. If you are unable to bring a device, let the course staff know and we will make other arrangements.

In total the in-class work will be worth 5% of your total course grade. Each of the N assignments will be P=5/N points. Grading for the exercises will be as follows:

- Exercise completed correctly in-class will be worth P points plus P points of Extra Credit
- Exercise completed correctly outside of class within 1 week will be worth P points.
- Exercise completed correctly after 1 week but before the end of the semester will be worth P/2 points.

These exercises can be done in groups and you can submit answers an unlimited number of times.

**Attending class and completing the work is a chance to earn 5% extra credit for the semester**

### 4 Credit Option

If you are taking the course for 4 credits, you will complete an extra project implelementing real-time transformation of web content for accessibility. The projects will be done in groups and we will release details by Week 3.

## Exams

This class will have three midterm exams and no final exam. The third midterm will be just before finals. Each exam is 50 minutes long.

- Midterm 1: Feb. 17 - Feb. 19
- Midterm 2: April 7 (online, details to be announced on piazza)
- Midterm 3: May 5 (online, details to be announced on piazza)

All exams are closed-everything (no book, notes, calculator, etc.). See the CBTF policies for more detail.You are responsible for all material covered in lectures and assignments.For DRES accommodations see CBTF DRES Students

## Grades

We will post grades on Compass 2g.

We weight grades as follows:

3 credits | 4 credits | |
---|---|---|

MP 1 | 10% | 10% |

MP 2 | 15% | 10% |

MP 3 | 15% | 10% |

MP 4 | 10% | 10% |

In-class Work | 5% | 5% |

Midterm Exam 1 | 15% | 15% |

Midterm Exam 2 | 15% | 15% |

Midterm Exam 3 | 15% | 15% |

4 Credit Project | 10% |

You can expect the cutoffs to be approximately as follows
98 - 100: A+

93 - 98: A
90 - 93: A-
87 - 90: B+
83 - 87: B
80 - 83: B-
77 - 80: C+
73 - 77: C
70 - 73: C-
60 - 70: D
Below 60: F

## Textbooks

There is no book for the class. Notes and other materials will be posted online. We do have some suggested books if you need help figuring things out:

*Fundamentals of Computer Graphics 4th Edition* by Steve Marschner, Peter Shirley

Deals with the theoretical and mathematical aspects of computer graphics. Very readable.

UIUC Library E-book link

*WebGL Programming Guide: Interactive 3D Graphics Programming with WebGL*

by Kouichi Matsuda and Rodger Lea

A bit old now, but pretty easy to read with decent example code.
