Proposed object-oriented approaches are still in an initial stage of investigation and are mainly limited to modelling CAD applications which manipulate ill-deened, evolving and multifaceted objects. In this paper , we argue in favour of a model, called CEDAR, which aims at easing the modelling process by endowing object-oriented approach with a viewpoint notion. keywords: object-oriented datab...

This paper describes a method to perform distance measurements inside buildings using a single video camera mounted on a mobile robot. This algorithm is designed specifically to create architectural floor plans with accurate measurements. Several issues associated with architectural surveying are discussed in detail, such as the visibility of features and the accuracy in calibration. Results of...

We present an interactive system called ArchiDNA for creating 2D and 3D conceptual drawings in architectural design. We developed a novel principle of shape generation called match-and-attach by analyzing drawing styles of a contemporary architect, Peter Eisenman. The process consists of user interaction techniques and a set of rules that decide how one ormore shapes attach to another shape. On...

Although computers prove useful in aiding human creativity, there is still shortage of adequate software for early-stage explorations in the design disciplines. One of such under-supported disciplines is architectural design. In response to this lack of proper software, architects adopted tools from other industries with a large level of success. However, despite the fact that several types of ...

The University of Auckland has been utilizing a multi-player game engine to develop an application (StringCVE) to coordinate architectural design and critique within a collaborative virtual environment (CVE). The initial emphasis of the research was to provide a low cost but feature rich alternative to commercial Virtual Reality (VR) in order to facilitate virtual design studios for architectur...

The ubiquitous computing era has pushed the Architecture, Engineering, and Construction (AEC) industry towards new frontiers of digitally enabled practice. Are these the frontiers originally identified by the pioneers in the field? Architectural design has progressively shifted from two-dimensional paper based pencil sketched models to digital models drawn in various Computer-Aided Design (CAD)...

An object oriented measurement approach using CAD models for the initialization of an automatic measurement process and for the verification of the measurement results is presented. CAD models are used in an a priori and a posteriori mode. The human operator assigns responsibility for the image understanding part (high level grouping), and the computer for the actual measurement and the data ha...
