Contract w/ Dr. Fairfield
• You must complete a contract with Dr.
Fairfield within two weeks of the start of
the semester or when you sign up for
the class.
• It must include arrangements on
grading, attendance, etc.
• I must also receive a copy of the
contract.

Tests, Quizzes, and
Projects
• Tests: There will be no tests as I can foresee
it. However, I might schedule one.
• Quizzes: I reserve the right to give
unannounced quizzes on material I have
covered in lectures.
• Projects: They are assigned in advance and
must be turned in by the due date at 4:30PM
in Dr. Fairfield’s office or Dr. Sochacki’s office.

Attendance & Lectures
• Attendance:
You are expected to
attend class
everyday and 10% of
grade is based on
that.
• Lectures:
I will give lectures
almost everyday.
Come prepared to
learn and respond to
ideas in class.

The Problem:
We want to view a 3D World on a 2D
surface such as a computer monitor
given an arbitrary view point and view
angles in that world. We want this world
to be as accurate as possible for us,
such that we can not distinguish it from
reality.

The Solution:
The answer lies in a mathematical
approach called Projections. Projections
transform 3D objects onto a 2D plane,
from which we are viewing. Before we
can discuss projections, we must
discuss the mathematical backgrounds
that form the basis of projections, which
is where we will begin next time!
