summary |
CAD systems regularly offer new techniques for the presentation of design proposals like computer-generated (stereo-) images, animations, holography and virtual reality. These techniques are mainly used for the presentation of a final design or for the presentation of buildings that have already been constructed. As in the course of time the quality of the CAD systems and their users have improved enormously, it is also possible to use these systems for the evaluation of several temporary design proposals during the design process. Since 'beautiful pictures' and 'wonderful animations' have already shown their great value when presenting a design, it is sometimes as if CAD systems are considered suitable for this propose only. Even new techniques like virtual reality systems seem to be valued only through the 'tinted glasses' of the presentation capabilities. Hardly any attention is paid to the possibilities that these new techniques offer as an instrument to support modelling and evaluation during the design process. This article will outline the results of research and development in the field of virtual reality. Virtual reality systems are based on the combination of a number of already existing presentation techniques like photo-realistic images, stereo images and real time animations. The added value of this type of CAD system is determined by the use of a new type of user interface. In effect this interface consists of sensors that register how its user moves and looks around. Through this, and by using a so- called 'eye phone' (comparable to stereo headphones for sound) the user, with some imaginative powers, thinks he is standing in the environment that he modelled, or in front of his building design. After this we will first sketch the outlines of some presentation techniques, that can also be found in a virtual reality system. Special attention will be paid to some specific characteristics of these techniques themselves. Next, a more detailed description will be given of virtual reality systems, focusing on the system that is being developed at Calibre itself. |
