Preparation
Design your "Recursive Torus"
Creative Design (cont)
Discussion of the "Recursive Torus Designs"
Analyzing the creative process:
- What did you think of first ?
- What are good design criteria for this problem.
- Is it manufacturable ?
Creating Computer Models from Surface Data
Basic idea:
-- Gather the 3D coordinates of surface points,
-- Connect them into a water-tight mesh.
A free utility to do that.
One of the original approaches by Turk and Levoy
Registring and integrating structured 2-manifold meshes.
A modern, robust approach by Curless and Levoy
Using a volumetric approach to the integration problem.
Siggraph movie -- as an introduction.
Current Homework Assignments:
READ: Curless and Levoy: "A Volumetric Method
for Building Complex Models from Range Images."
Answer the following question in writing with one paragraph each,
and hand in your write-up
either electronically before 9am, Mon. 4/10/00,
or in hard copy in class at 10:40am, Mon. 4/10/00,
- What is the "volumetric" nature of the approach;
how does the use of 3D space help in creating better models?
- What are the major sources of uncertainty and error in the scanner type used?
- How do the authors deal with portions of the surface that are "never seen"
by the scanner ?
