Intuitive Methods for 3D Shape Deformation
Rice University
Deformation is a key component in many applications including virtual surgical
simulation and the animation of digital characters in the movie industry.
Previous deformation methods have led to non-intuitive ways of specifying the
deformation or have been too expensive to compute in real-time. This talk will
focus on three methods we have developed for creating intuitive deformations of
3D shapes. The first method is a new, smooth volumetric subdivision scheme that
allows the user to specify deformations using conforming collections of
tetrahedra, which generalizes the widely used Free-Form Deformation method. The
next technique extends a fundamental interpolant in Computer Graphics called
Barycentric Coordinates and lets the user manipulate low-resolution polygon
meshes to control deformations of high-resolution shapes. Finally, the talk
will conclude with some of our recent work on creating deformations described
by collections of points using a technique called Moving Least Squares.
Hosted by John Bennett.
The speaker is a candidate for a faculty position in the Department of Computer Science.

The Department holds colloquia throughout the Fall and Spring semesters. These
colloquia, open to the public, are typically held on Thursday afternoons, but
sometimes occur at other times as well.
If you would like to receive email notification of upcoming colloquia,

Colloquia Mailing List.
If you would like to schedule a colloquium, see
Colloquium Scheduling.
Sign language interpreters are available upon request. Please contact
Stephanie Morris at least five days prior to the colloquium.
