Office hours: Tuesday, 4-5pm
What we will cover:
There are many courses that can teach you how to use commercial computer graphics packages and APIs. This course, in contrast, will teach you how to build 3D computer graphics from the ground up. This will include 3D modeling, animation, and rendering. At the end of the semester you will have built your own complete working real-time 3D computer graphics systems that runs in web browsers.
What you should already know:
On the other hand, if you are not already an experienced programmer, then I do not suggest you take this course, as there will be weekly programming assignments, and you will not be able to keep up.
Computer graphics uses a lot of matrix math and some calculus. During the semester we will go over all of the matrix and vector math that you will need.
Class notes (so make sure you come to class!), will be posted on-line after each lecture.

Setting up a homepage and access to computers:
Most of you have the homepage and computers thing already figured out. But just to make sure you have at least one way to show your work on line, your NYU webpage can be activated and modified as follows:
To post assignments for this class, you should set up a subdirectory of your web site (preferably your NYU web site). Name this subdirectory "graphics". It should have a main "index.html" file, and that file should link to the various homework assignments. After the first class, you will send the grader an email, with subject line "graphics", telling him the URL.
For our introductory lecture I mainly went over the high level ideas of what we are going to do in this course, and showed some examples of computer graphics in action.
Homework assignment for this class, due before the start of next class: Put up on your class web page an essay describing what motivated you to take this course (eg: are you hoping to do computer graphics to make movies?), and any topics, material or ideas in particular you would like to see covered in this semester's class.
Here are links to the computer animations we saw and discussed in class:
Night on Bald Mountain from Disney's Fantasia
The Works from New York Institute of Technology
MAGI Norelco commercial
Toy Story trailer
Fiat Lux by Paul Debevec
Snack and Drink (graphics + rotoscoping) by Bob Sabiston
Battlefield 4 for Playstation 4
Real time WebGL demo (with caustics and physics) by Evan Wallace
Carlitopolis by Luis Nieto
Worldbuilder by Bruce Branit
In this class we discussed, at a high level, the technical elements of computer graphics, covering the basics of color theory and shape modeling, and implications of rendering via ray tracing versus zbuffering (although we did not yet describe how to implement these rendering techniques).
Course notes for some of these topics are now on-line HERE.
We also briefly discussed linear transformations and 4×4 matrices.
Your assignment, due next Wednesday before class starts, is to download code1.zip, unzip it, modify the shader code you will see in the code1/ directory, and post your results on your class web page.
Note that you will need to create a subdirectory for this assignment, which will contain two files: (1) your modified version of index.html, and (2) script.js -- which you should not modify.
To learn how to enable WebGL for your browser (Safari or Firefox or Chrome, but not Internet Explorer), you can follow these instructions.
