Colloquium - Schaefer


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, subscribe to our 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.
