title Discussing Image-Based Modeling Technology for 3D Digital Archival of Physical Architecture Models

summary Besides drawings, physical models are important forms of representation commonly used for architectural design. They can serve as a useful resource for teaching and research, provided there is a proper archiving system that allows easy retrieval. Architectural models in 3D digital format seem to be able to overcome the limitation of physical constraints they can be easily accessed anytime and anywhere over the Internet. The most common way of 3D model documentation is through geometric-based 3D CAD software. Image-based modeling (IM) allows the 3D digital model to be created from photographic images. Debevec (1998) investigated the hybrid geometry- and image-based approach whilst Tsou (2002) and Hawkins (2001) focused on the application of IM for GIS and digitizing cultural artifacts respectively. This paper aims to compare physical models and their IM counterparts in terms of communication of vital architectural information. Experiments were conducted to evaluate the extent the IM model resembled the physical predecessor in terms of its geometry and visual appearance qualities/faithfulness. A survey was subsequently carried out to compare their performance in terms of the communication of vital architectural information about building designs to the observers. The tabulated results were then examined to help understand the opportunities and weakness of IM for 3D archival of physical architecture models
