CIS788.Y14
Sample Based Geometric Modeling for Graphics and Visualization


Instructor Tamal K. Dey

Course Description

Recent advances in scanning technology and scientific
simulations can generate sample points from a geometric domain
at ease. Inferring the shape and their features from such
a simple light-weight input can be a very effective modeling paradigm
across many areas of science and engineering. In this talk
we will go over the techniques developed for such modeling
paradigms. In particular, we cover algorithms for
(i) extracting a surface out of point samples, (ii) computing
an approximate medial axis of the sampled object, (iii) segmenting
the object into so called ``features". Theoretical concepts along with
experimental results will be presented.

Grading

Grading will be based on three things.
A. Experiment with the Cocone software (will be provided) on data from your application
and study its results.
B. A  Term paper at the end of the course on a related topic of your choice.
C. Your class participation.
