Preparation: Functional Optimization for Fair Surface Design (MVS) by Moreton and Séquin

Warm-up: Discuss with your neighbors the following task:

You would like to make your genus-4 mesh as "round" as possible. Specifically,

you would like to minimize the maximum of curvature anywhere on the surface.

How would you go about doing this ?

Topic: Surface Optimization

Introduction and Motivation to Minimum Variation Surfaces

Discussion of the salient points of the papers: Data structures, algorithms, difficulties ...

Start preparing for your 5-minute formal Project Proposal Presentation on November 2.

("Venture Capitalist Rally" -- How to get the "gold".)

Format:

Should last 4-5 minutes (hard 5 minute cutoff).
Start with an attention-grabber.
Be enthusiastic, make an impact.
Your peers will rank-order your performance.

Content:

The goal of the project
The approach you will take
The deliverables and demos resulting
Why this is a "good" project (somewhat of a "selling" job):

how useful it might be, or
just how "cool" it is going to be, or
what you hope to learn with this project ...

Check list and rating sheet:

Reading Assignment:

Progressive Meshes

Ongoing Programming Assignment:

Add texture mapping to your triangle subdivision scheme.

By WED, Oct. 28, you should be able to present a genus-4 surface with some non-trivial texture mapped onto it.
Send me: a pretty picture, an updated description of your encoding scheme and your data structures,
and a brief discussion of some of the design choices you have made.
TESTING HINT:
Make sure merged serface is a watertight 2-manifold B-reps of a real solid object !
Run files in SLIDE and "save as SIF" (with backface eliminattion; NOT SLF_HOLLOW);
-- Inconsistent (unmatched) edges joint will then be shown as red lines.
If everything is OK, the SIF file will report a single shell of the proper genus.

COURSE PROJECTS:

Monday, Nov. 02: You will make a formal 5-minute presentation in class.
