Physics 1905.3
Physically Realistic Animation
Pete Border, lecturer
Fall term , 2002
Welcome to physics 1905.3! We will be exploring learning physics through making animations
and games. Physics is used extensively in animations and games; without getting the physics
right, you can't make a realistic movie. We will try to keep the technical side of the course as
easy as possible, but some programming is inevitable. The main language we use will be
Python, which is a very high-level scripting language (you can read more at
http://www.python.org). We will use python with the vpython extensions
(http://www.vpython.org) and as a scripting language in Blender (www.blender3d.com), a free
animation software package.
News
This week we talked about classes and OOP on Tuesday, and finished covering collisions on
Thursday. Your homework is to make a vpython game featuring collisions. It is due in class on
Oct. 22.
Next week we will discuss the homework on Tuesday, and begin with planar rotations on
Thursday.

Phys1905.003 Fall 2002 Syllabus

Physics 1905.003 Fall 2002
Syllabus
Dr. Peter Border, teaching
Welcome!
Welcome to Physics 1905.003! This course is about exploring how things move with
the tools of computer animation and simulation. Making a believable animation
requires a good understanding of motion, and flaws are very apparent. The human
brain is very good at detecting unrealistic motion, so looking at motions in simulation
should produce immediate feedback on how well the physics is understood.
On the other hand, physically correct motion is a tremendous boon to lifelike
animation. Puppeteers have known for centuries that making something move like a
human makes people see it as a human being, even though it may have almost no
resemblance to a human being when it is still. See, for example, Karl Sims virtual
creatures. When stopped, they are just a series of boxes, but, moving, they make
most excellent fish.
The plan for this course is to teach the physics of motion concurrently with the
technology needed to illustrate the motion. There are several technological tools
available to us, of varying degrees of complexity. The final set of tools we wind up
using will depend on how things go during the semester, and it is quite possible that
not everyone will use all the tools (grading will not depend on which tools people use,
but on how well they use it).

Phys1905.003 Fall 2002 Syllabus
The text for this course is Physics for Game Designers, by David Bourg. It is available
at the University bookstore.
You will be required to download various free programs through the semester. If there
is need for it, the downloads can be supplied on CD for those without high-speed
lines.
Course Structure
Physics 1905 has two parts- the lecture and the homework.
Lectures
Physics 1905.300 will meet on Tuesday and Thursday afternoons from 3:30 to 4:30 in
Physics 210. Generally, Tuesdays will be spent going over projects (you may be made
to explain your project to the group!), and Thursdays will be more formal lectures.
Lecture notes will be posted on the internet, but blackboard work done in class will not
be.
Websites, Chat Rooms, Bulletin Boards and Such
There will be a course website, hosted the UMN WebCT. The URL will be
The website will eventually contain links to
m The syllabus you're reading now
m Class news
m Lecture notes- these will not contain any work done on the blackboard, so you
really should come to class!
m Links to any surveys, bulletin boards, chat room schedules, etc
The website will be hosted by the University-wide WebCT server, so chat rooms,
whiteboards, discussion lists, etc. are available.
Office Hours
The lecturer for this course is Dr. Peter Border, who can emailed at

Peter Border
Room 257, Tate Lab of Physics
612-624-1020
My office hours will be on Wednesday mornings from 10:00- 11:00, or by appointment.
Projects
Final grades will depend on projects. Each week, a homework project will be assigned
on Thursday. It will be due the next Tuesday, and you are quite likely to be called in
front of the class to discuss your work. Some projects will take several weeks to finish.
These projects should count more in the final grade, so each project will have a weight
equal to the number of weekends between the assignment and the due date. Note
that even if a project is not actually due on some Tuesday, you will still be required to
give a progress report on that day, and “no progress” will not be a good answer.
Many of the projects will be done in groups. Each person in the group will receive the
same grade for a group project. If you feel that you are doing more than your fair
share of the work in your group, see the instructor.
Several of the assignments may seem rather vague, especially if you've taken physics
courses before. The assignments are meant to open up frontiers to you, and to allow
you to find physics in your everyday life, rather than imposing some abstract,
meaningless exercise. Try to have fun with them- if something isn't specified in the
problem statement, make it up!.
Tentative Schedule
This schedule will be subject to change!
