Virtual environments (VEs) very often contain buildings that have to be navigated by users. In the literature, several navigation aids based on maps have been proposed for VEs, but in virtual buildings they have been typically used for single-floor scenarios. In this paper, we propose and experimentally evaluate two different navigation aids for multi-floor(More)
In this paper, we propose the Interactive 3D BreakAway Map (I3BAM), an extension of the well-known Worlds In Miniature [6]. The I3BAM supports user navigation in virtual buildings as a navigation aid, but also provides a means of examining any floor of a virtual building without having to necessarily navigate it. The aid presents multiple views of a virtual(More)
Feature technology has been evolving since the early 1980s, yet is still found in few commercial CAD systems. Traditional CAD systems provide support for geometric design and limited parametric design. Two basic approaches to feature modeling have been developed: design by features and feature recognition. Each of these methods provide specific tools to(More)
