this panel will address the technical, economic and marketing hurdles that inhibit the widespread use of cloth/clothing modeling, design and animation technology. Many of the fundamental technologies needed to support cloth modeling have already been developed. Still, we do not see computer-animated characters wearing realistic clothing, and clothing designers are not creating new fashions withcomputer-based 3-D design systems. the CAD industry is capable of providing the systems for designing the Boeing 777, but almost none of the clothing we wear is designed with 3-D CAD tools. the panel will explore the reasons that the design of cloth and clothing, a material that has been a part of the human experience for thousands of years, has not yet been fully computerized.
Manipulation in immersive virtual environments is difficult partly because users must do without the haptic contact with real objects they rely on in the real world to orient themselves and their manipulanda. To compe...
