Designing in Virtual Reality: Modelling Objects in a Virtual Environment (MOVE)

摘要

The authors describe a CAD system developed to provide designers with modellingtools that can be used in a virtual environment. The authors discuss the design of the environment and the way in which the user is assisted to perform his task in the virtual environment. The MOVE system allows the user to operate in an intuitive and everyday style of work. This is done by offering tools that can be grabbed and handled. Each tool enables a designer to directly manipulate and transform the virtual models in a specific way, providing appropriate visual, auditory and tactile feedback during the operation. With these tools designers can recapture the three-dimensional aspect of building and shaping models, which is lost when working behind computer screens. The authors will describe parts of the functionality of the MOVE system and the way they used the four level approach by Foley to develop the program.
