4Dive - A 4D Interface for the Visualization of Construction Processes in a Virtual Environment

Abstract: In this paper we present 4DIVE, an interface concept for the visualization of construction processes in Virtual Reality (VR). It supports process management tasks of the AEC industry in the field of Virtual Design and Construction (VDC). 4DIVE is developed for the use in projection based Virtual Environments (VEs) like the CAVE or large scale projection walls, supporting stereoscopic visualization in real-time and 3D user tracking. The 4DIVE project focuses on the design of interaction concepts addressing the following topics: (1) The integration and visualization of 4D CAD models in VR systems, (2) the development of 4Record, a tool for recording and replaying paths in the 4D time-space, and (3) the design of suitable input devices and interaction techniques.

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.

Development of virtual reality applications for the construction industry using the Oculus Rift head mounted display

Abstract: 3D visuals are a fundamental part of virtual reality that we often take for granted. Yet when we simulate 3D we often neglect to accurately reproduce the basic concept of depth perception. This document discusses possible applications for stereoscopic head mounted displays within the context of the construction industry and seeks to highlight the technical considerations of using such technologies.

Display and Rendering Technologies for Virtual and Mixed Reality Design Review.

Abstract: In this paper we introduce an innovative application designed to make collaborative design review in the architectural and automotive domain more effective. For this purpose we present a system architecture which combines a variety of visualization technologies such as high resolution multi-tile displays, TabletPCs and headmounted displays with innovative 2D and 3D Interaction Paradigms to better support collaborative mobile mixed reality design reviews. Our research and development is motivated by two user scenarios: architectural and automotive design review involving real users from Page\Park architects and FIAT Elasis. Our activities are supported by the EU IST project IMPROVE aimed at developing advanced display techniques, fostering activities in the areas of: optical see-through HMD development using unique OLED technology, marker-less optical tracking, mixed reality rendering, image calibration for large tiled displays, collaborative tablet-based and projection wall oriented interaction and stereoscopic video streaming for mobile users. The paper gives an overview of the targeted scenarios and focuses in particular on the rendering aspects of the project.
