PreRequisites

Technically, Data Structures and some familiarity with linear algebra.

Main Textbook

Peter Shirley. Fundamentals of Computer Graphics, 3^rd ed.

Reference books

Mason Woo, et al. The OpenGL Programmer's Guide.

This is sometimes known as the "red book."

The current edition is the 6th edition, but for the purposes of this class an older edition would be OK too. If you don't want to buy this book, the complete contents of the older version is online in html. There used to be an online PDF version as well, but it seems to have vanished. The old edition is OK for most things, the critical chapter in the 6e will be provided online in class.

There will be some readings from this book, and its an important reference.

Tomas Akenine-Mller and Eric Haines. Real Time Rendering, 3e.

This book is specifically about real-time rendering, and is very useful if you're interested in interactive stuff like games. It is really well written, and has great discussions of a lot of the basic topics. The new edition just came out (so new its out of stock most places), and is quite encyclopedic. Its an awesome reference book, but a little hard to learn from, so I highly recommend it if you are serious about graphics.

Gregory Junker, Pro OGRE 3D Programming (Expert's Voice in Open Source)

This book gives you the fundamental information for OGRE programming.

Exam

There will be 1 exams, counting for 20% of your grade.

There will be a take-home final exam at the last class.

Grading

Projects (10, 10, 15, 15, 30% each): 80%
Final: 20%
