Lightweight 3D IFC visualization client

Abstract: We describe a construction product model 3D visualization client software concept that can be used in advanced meeting room, virtual reality and construction site augmented reality applications. Its main target is to im-prove construction project communication and understanding through visualization. It provides Industry Foundation Classes (IFC) geometry visualization capabilities to existing applications that can incorporate a Universal Plug and Play (UPnP) module to communicate with the visualization client at runtime. To accomplish this we present a software architecture based on UPnP networking standard that allows the visualization client to engage in two way runtime data exchange with existing construction project applications such as project management, cost estimation and quantity cal-culation applications. The client runs on laptop, desktop and portable tablet PCs. It offers stereoscopic viewing and spacemouse navigation for immersive virtual reality applications and live camera source background as well as exter-nal viewpoint control for augmented reality applications. We describe some usage scenarios of this concept, compare it to others and present early results as this work is part of an ongoing effort in Virtual Building Environments project.

Keywords: virtual reality, augmented reality, advanced meeting rooms, ubiquitous computing, IFC visualization
