CS 39R:  Symmetry & Topology
Lecture #4 -- Mon. 2/25, 2013.

Preparation:

Think about how you would extract structural or approximate symmetry from "almost symmetrical" objects such as those:

   

How would would you describe algorithmically what you are doing intuitively for such a task?
How could you instruct a computer to do such a task for you?
What kind of a user interface would you like to see?

Warm-up:

Think about other scenarios where it makes sense to try to extract some underlying conceptual symmetry.

Guest Lecture by James Andrews

(PhD Work:  User-Guided Inverse 3D Modeling)

Discussion Topic:

How we can use computers to find symmetry in 2D images and in 3D models

Continuing Homework Assignment:

Make a real (physical) model of a genus-6 object of high symmetry;
use: clay, paper, styro-foam, pipe cleaners, . . .
