Paper ISMAR 2009: "Augmenting Aerial Earth Maps with Dynamic Information"

Augmenting Aerial Earth Maps with Dynamic Information Abstract We introduce methods for augmenting aerial visualizations of Earth (from tools such as Google Earth or Microsoft Virtual Earth) with dynamic information obtained from videos. Our goal is to make Augmented Earth Maps that visualize the live broadcast of dynamic sceneries within a city. We propose different […]

Thesis: Gabriel Brostow's PhD (2004): "Novel Skeletal Representation for Articulated Creatures"

We define a Spine as a branching axial structure representing the shape and topology of a 3D objects limbs, and capturing the limbs correspondence and motion over time. … In general, our approach combines the objectives of generalized cylinders, 3D scanning, and markerless motion capture to generate baseline models from real puppets, animals, and human subjects.

Thesis: Irfan Essa's MS Thesis (1990): "Contact detection, collision forces and friction for physically based virtual world modeling"

Publication Abstract Detection of contact and calculation of collision forces is an important problem in any kind of physical multi-body simulation. For computer graphics and physically-based animation, it is especially important to devise methods that combine efficient computational methods with powerful existing graphics tools if one is to obtain a realistic, real-time virtual world. Most of the physical simulations are computationally […]

Paper in ACM I3DG (1990) "The ThingWorld modeling system: virtual sculpting by modal forces"

Paper Abstract We describe a real-time solid modeling system that is based on the physical analogy of forming clay by applying forces. The system is implemented by simulating real materials as they react to user-supplied forces. Unlike other physically-based modeling approaches, the Thingworld system allows the user to restrict forming action to simple global deformations […]
