In this paper we present a technique for the modelling and animation of cartoon hair. In our approach the primary shape and motion of the hair is defined by an animated NURBS volume, along whose surface are generated clumps of hair geometry. The basis of these hair clumps is formed by key hair curves that are grown along the isocurves of the originating(More)
A universal concern of those in nursing care is the occurrence of decubitus ulcers. To minimize this problem foam overlays are routinely used on hospital beds throughout the country. This study was undertaken to develop laboratory testing procedures which will reliably predict the support characteristics of mattress overlays in clinical service. Initially,(More)
3D computer animation often struggles to compete with the flexibility and expressiveness commonly found in traditional animation, particularly when rendered non-photorealistically. We present an animation tool that takes skeleton-driven 3D computer animations and generates expressive deformations to the character geometry. The technique is based upon the(More)
Clinical medical devices are designed with the explicit assumption that trained medical team members will operate them in appropriate hospital environments. As technological complexity increases, along with the possibility to create specific ward configurations, the potential for unusual interaction combinations poses challenges for safety and training.(More)
