Interactive Sketch-Based Shape Modeling: In Search of the Human Video-Out
Thursday, October 23, 2008, 12:00pm - 07:00pm
Rutgers University, Department of Computer Science
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".
