Overview and Objectives

This course will provide an introduction to computational techniques for generating animation. Topics will include methods which have applications in the creation of movie effects, the development of video games, and training simulations. While the focus will largely be on physically based methods for the automatic generation of motion, part of the course will cover methods for user control of animation and reuse of captured motion data. See the schedule below for a list of topics.

The main objective of this course is to have students develop an understanding of fundamental techniques used for computer animation. At the end of the term, students will be able to identify the advantages and disadvantages of using simulation, procedural animation, motion capture, and hand designed animations, with respect to both online and offline applications. You will also be able to implement animation techniques, using common software languages and tools. Finally, in addition to an understanding of current practices in computer animation, a general objective is for students to better recognize current important challenges in computer animation.

Prerequisites

Undergraduate students taking this course should have already taken COMP 557 (Fundamentals of Computer Graphics). It is also suggested that undergraduates have already taken COMP 350 (Numerical Computing), or ask for consent of the instructor if they have sufficient mathematical maturity. Students taking this course should have good knowledge of linear algebra (linear systems, eigenvalues), calculus (basic differential equations, vector calculus, partial derivatives), and be comfortable programming in Java for assignments. Some review will be done in class when necessary or appropriate.

Course format and evaluation

The class will be taught through a series of lectures. Grading will be largely based on assignments and a project. The intent is for students to get hands on experience with the material in the course. There are four components to the grading scheme.

  • 40% assignments (4 programming assignments)
  • 30% midterm exams (two in class tests, 15% each)
  • 30% project (write up, presentation, and oral on April 25)

Projects can be a significant extension of a previous assignment or something of your own choosing. This highlights reel from the 2009 offering of this course may give you some additional inspiration.

Assignments

Assignments must be all your own work. You are still encouraged to discuss material related to the assignments with your classmates, that is, discuss your assignments, problems, or solutions as a group, but you are ultimately responsible for understanding the material and the programming and write up must be all your own work. If you do talk with your classmates about the assignment, then you must list the names of everyone with which you discussed the assignment, or state that you discussed with nobody.

See below the section on things you should already know about academic integrity. Also note that you can submit work in French if you prefer. If ever you feel you can't complete the work, talk to me, or your advisor, and we can help you figure out what to do (i.e., don't wait until the end of the term).

Programming assignments must be submitted electronically (follow the instructions in the assignment specification). Package structure should be preserved in your zip file. Do not use any other archive type. Please check carefully the time at which assignments are due and do not leave it until the last minute to submit! Late assignments will be accepted up to three days after the deadline and will receive a penalty of 10%.

You should always check your submission by downloading your assignment from the server and checking that it is what you intended to submit. The written component of an assignment, if any, must be submitted as a PDF (i.e., a clear scan, or photo, or use latex or some other typesetting software). Readme files should always have a .txt ending.

Here follows the list of tentative assignment topics. Note that there will only be 4 assignments and for each you will have two weeks to complete the objectives (you will have more than three weeks for the project).

  • Mass-spring particle system
  • Rigid body collision and response
  • Eulerian fluid simulation
  • Motion capture reuse and character simulation
  • Physics based character control
  • Continuous collision detection
  • Implicit simulation of cloth with constraints
  • Inverse kinematics

Texts and Resources

Material in this course will come from a number of sources. All suggested and supplementary texts will be on reserve at the Schulich library. The CAAT book is recommended for students wanting an general resource and slightly gentler introduction to the material, while the PBA book is suggested as a good supplementary resource on the Physics-Based Animation topics. The course will also make use of a number of excellent free online resources (PBM, MLS), and additional notes on selected materials will be provided through out the term.

In case you didn't already know...

McGill University values academic integrity. Therefore, all students must understand the meaning and consequences of cheating, plagiarism and other academic offences under the Code of Student Conduct and Disciplinary Procedures. See www.mcgill.ca/integrity for more information, as well as www.mcgill.ca/students/srr/honest with respect to student rights and responsibilities.

It should be noted that, in accordance with article 15 of the Charter of Students' Rights, students may submit examination answers in either French or English.

According to Senate regulations, instructors are not permitted to make special arrangements for final exams. Please consult the Calendar, section 4.7.2.1, General University Information and Regulations at www.mcgill.ca. Special arrangements in emergencies may be requested at your Student Affairs Office. If you have a disability, please advise the Office for Students with Disabilities (398-6009) as early in the term as possible so that we can provide appropriate accommodation to support your success.

In the event of circumstances beyond the instructor's control, the evaluation scheme as set out in this document might require change. In such a case, every effort will be made to obtain consensus agreement from the class.

Additional policies governing academic issues which affect students can be found in the Handbook on Student Rights and Responsibilities.
