    Clothing the Masses: Real-Time Clothed Crowds With Variation
    (The Eurographics Association, 2006) Dobbyn, S.; McDonnell, R.; Kavan, L.; Collins, S.; O'Sullivan, C.; Dieter Fellner and Charles Hansen
    The animation and rendering of crowds of realistically clothed characters presents a difficult challenge in computer graphics, which is further exacerbated when real-time frame rates are required. To date, due to real-time constraints, standard skinning methods have been used to animate the clothes of individuals in real-time crowds, which does not create the appropriate secondary motion for flowing garments. However, plausible cloth simulation is vital for the depiction of realistic characters, so we have developed a novel crowd system in which the individuals are endowed with realism and variety through the addition of physically simulated clothing and hardware assisted pattern variation.

    Harnessing the Human Visual System for Image Based Modeling: an Interaction System
    (The Eurographics Association, 2006) Morvan, Y.; O'Sullivan, C.; Dieter Fellner and Charles Hansen
    We present a novel interaction system for modeling 3D geometry from photographs. Given a set of stereo pairs, along with their camera parameters, the interface tracks the movements of the users and allows them to intuitively position the modeling tools in 3D and to browse the stereo pairs using head movements. The geometry being modeled is overlaid on the photographs using a stereo display. The use of the known camera parameters for displaying the geometry ensures proper registration with each photograph and thus results in correct 3D models.
