### Lectures and Tutorials

Monday, Wednesday 08:30-09:20, Friday 10:30-11:20, BSB/B155. (Subject to change)
Tutorials/Labs:

• T01: Monday 14:30-16:20 in ITB/237

### Instructor

Dr. J. Carette, ITB-168 , ext 26869, email: carette at mcmaster dot ca.

Office hours: by appointment (or catch me after class).

For all course related questions, a class forum has been set up on WebCT so that questions and their answers can be posted centrally. The instructor will generally not answer emails sent to him directly, but will answer questions posted on the discussion forum(s) very frequently. [Questions of a personal nature can still be emailed to the instructor]

### Teaching Assistant

Hong Ni -- (email tbd)

### Textbook

Required: Game Physics, by David Eberly (Elsevier/Morgan Kaufmann).

### Course Objectives

The calendar description says: Design of time-evolution of/in three dimensional spaces. Dynamical systems (discrete and continuous). Physical and artificial systems. Design patterns of 4D modelling. This basically means the mathematical and physical foundations of moving three dimensional objects, and their implementation methods.

In more detail, the topics that will be covered during the weekly lectures are:

• Basic concepts from Physics:
• Rigid bodies
• Newton's laws
• Forces
• Momenta
• Energy
which corresponds to all of Chapter 2 in the textbook.
• Rigid body Motion, done using Newtonian Mechanics (Sec 3.1)
• Overview of Physics Engines. Software patterns of simulation software (Sec 5.1 and parts of 5.2). Includes
• Unconstrained Motion
• Constrained motion -- collisions
where the latter topic was covered the GJK algorithm in detail as the modern way to implement this.
• Differential Equations. As these are so central to the domain, all of Chapter 8
• Difference equations - a quick overview of concepts, mostly done as a quick parallel to modelling with DEs from a dynamical point of view.

The topics will be covered in essentially the order given above.

### Course Information on Web, and Slides

The latest version of this outline and the most "up-to date" information as well as hand-outs can be found on the course web page. http://www.cas.mcmaster.ca/~carette/SE3GB3/2007/index.html.
(Or go to my home page and then to the course page). The slides and assignments can be found there as well.

• There will be two midterms. They will be scheduled during the regular class hour, and will be held in the normal class as well.
• The final examination will be scheduled by the Registrars office in the usual way. It will be three hours in duration and cover all of the material of the course, including the handouts and the assignments.
• It is essential that you fulfill the deadlines for the assigments, there is no credit for documents handed in after the deadline.
• The final grade will be computed according to:
 Final Examination 50% Mid-Terms 30% Assignments 20% = 4 x 5%

Assignment will also generally contain bonus material, whose marks will be added directly to the final mark. Assignments will be clearly identified as individual or group work. Assignments are to be submitted online, through WebCT.
• The instructor does not accept late doctor's notices, if you write a mid-term then the mark is yours. If you do not write an exam or an assignment and do not provide an acceptable doctors note then it is marked with 0. The instructor reserves the right to conduct any deferred exams orally.

### Notes:

#### Discrimination

"The Faculty of Engineering is concerned with ensuring an environment that is free of all adverse discrimination. If there is a problem that cannot be resolved by discussion among the persons concerned individuals are reminded that they should contact their Chair, the Sexual Harassment Office or the Human Rights Consultant, as soon as possible."

You are expected to exhibit honesty and use ethical behaviour in all aspects of the learning process. Academic credentials you earn are rooted in principles of honesty and academic integrity.

Academic dishonesty is to knowingly act or fail to act in a way that results or could result in unearned academic credit or advantage. This behaviour can result in serious consequences, e.g. the grade of zero on an assignment, loss of credit with a notation on the transcript (notation reads: “Grade of F assigned for academic dishonesty”), and/or suspension or expulsion from the university.

The following illustrates only three forms of academic dishonesty:

1. Plagiarism, e.g. the submission of work that is not one’s own or for which other credit has been obtained.
2. Improper collaboration in group work.
3. Copying or using unauthorized aids in tests and examinations.

Individual assignments have to be solved by one person only, any outside source, this includes asking other people, or using any books or information found on the web has to be documented. In complience with the senate regulations on academic integrity I remind you that: People who let other people copy are as guilty as the ones who copy. You are allowed to consult outside sources, meaning textbooks or the web, but any use of an outside source must be documented. Similarly, group assignments must be solved by members of that group only, and the above policies apply as well.

In the case the instructor or a TA has the impression that an assignment is copied, the instructor can ask the corresponding students to explain exactly how the assignment was prepared and take appropriate actions.

#### Online Component

In this course we will be using WebCT. Students should be aware that, when they access the electronic components of this course, private information such as first and last names, user names for McMaster e-mail accounts, and program affiliation may become apparent to all other students in the same course. The available information is dependent on the technology used. Continuation in this course will be deemed consent to this disclosure. If you have any questions or concerns about such disclosure please discuss this with the course instructor.
