The idea of Virtual Prototyping is the use of realistic digital
product models for design and functionality analysis in early
stages of the product development cycle. The goal of our research
is to make modeling of virtual prototypes more intuitive and
powerful by using knowledge enhanced Virtual Reality techniques
for interactive construction of virtual prototypes from
3D-visualized, CAD-based parts. To this end, a knowledge-based
approach for real-time assembly simulation has been developed
that draws on dynamically updated representations of part matings
and assembly structure. The approach has been implemented in an
experimental system, the CODY Virtual Constructor, that supports
a variety of interaction modalities, such as direct manipulation,
natural language, and gestures.
