3D visualization using the Pocket PC

The recent introduction of Windows CE-based Pocket PC’s has changed the role of handheld devices from a PDA with basic functions to a miniature extension of the personal desktop computer. A major advantage of Pocket PCs is mobility. They fit in the users pocket and can be easily carried anywhere. The continuously increasing processing power embedded in these devices allows Pocket PC users to develop and run many applications that were, at one time, only available for the desktop platforms. Up till the early 90s. Virtual Reality (VR) and 3D visualization applications were envisioned to run only on desktop platform and highly powered graphics workstations such as the Silicon Graphics Octane. VR technology allows for real-time interactive visualization and walkthroughs [1]. In construction projects, it can be used to visualize walkthrough, interaction, modification in real-time a facility and its components and also testing what-if scenarios for various construction alternatives. The ever evolving development of microprocessors, 3D graphics and chips, and 3D software have made it possible for VR and 3D visualization applications to migrate to the desktop PC, and most recently to the Pocket PCs. This paper explores the use of the Pocket PC platform coupled with multiple VR applications for visualization of design components and assemblies of building projects. It summarizes the proposed development of the needed to bring visualization environment into the realm of Pocket PC which could eventually be used as a visualization tool in construction. We used an iPAQ Pocket PC with 64 Mb of memory installed from Compaq.
