Digital 3D models are ubiquitous. Yet, for the creation andmodification of 3D models we rely on highly specialized tools, whichunfortunately limits the user base to trained professionals. In thistalk I will describe and demonstrate two of my recent projects thatare designed to alleviate this problem. Generating plausible andvisually pleasing shapes and deformations is far from trivial: whileour capability to derive a mental model from everyday shapes around usis well developed, we fail to properly communicate this to a machine.This is why we have to model in a loop, constantly correcting theimproper interpretation of our intentions. Ideally, a sketch-basedmodeling system for 3D shapes should use the very same sketches thatdesigners would draw on a piece of paper to convey the shape. Butwhich lines are best suited for this task? The tools I willdemonstrate use a subset of such feature lines. And although theserepresent a good trade-off between complexity and usability, I willargue that this is only one of many steps towards the notion of a"human video-out".

"What is Cognitive Science?"

This lunchtime talks series is designed to introduce the University community to issues in Cognitive Science. Cognitive Science is one the the few fields where modern developments in computer science and artificial intelligence promise to shed light on classical problems in psychology and the philosophy of the mind. Ancient questions of how we see the world, understand language, and reason, and questions such as 'how a material system can know about the outside world', are being explored with the powerful new conceptual prosthetics of computer modeling.

The talks in this lunchtime lecture series are every Thursday during the Fall semester from ** 12:00-1:00 ** in the Psychology Building, Room 101 on  Busch Campus.

Note: Talks are also announced by email (with reminders sent the day of the talk) to people who have requested to be placed on our announce list. If you would like to be added to our announce list, please email the Business Office (business_manager@ruccs.rutgers.edu).
