Projects in the area of architectural design and urban planning typically engage several architects as well as experts from other professions. While the design and review meetings thus often involve a large number of cooperating participants, the actual design is still done by the individuals in the time in between those meetings using desktop PCs and CAD applications. A real collaborative appr...

An Integrated Design Environment facilitates co-operation between different disciplines. The paper investigates the data modelling framework, distinguishes between homogeneous and heterogeneous model worlds, discusses the formal mapping mechanisms available to establish a heterogeneous model world, and introduces a way to incorporate CAD systems into IDE. A prototype IDE has been developed to p...

Agent-based, decision-support systems provide human decision-makers with a means of solving complex problems through collaboration with heterogeneous collections of both human and computer-based expert agents. Over the past decade the Collaborative Agent Design (CAD) Research Center has developed several proof-of-concept and production-oriented agent-based, decision-support systems for both com...

A standardized, object-oriented building product model for buildings is introduced that can be used as a means of electronic exchange between various software tools. The ability to transfer architectural data between a commercially available computer-aided design (CAD) program and a widely available zone fire simulation tool illustrates the applicability of this model in fire engineering. This ...

This paper gives an introduction to some of the basic concepts in the book, A Generative Theory of Shape (Michael Leyton, Springer-Verlag, 2001). The book develops a new mathematical theory of design, and supports this theory with lengthy analyses of mechanical CAD/CAM, architectural CAD, solid modeling, kinematics, etc., as well as the principal areas of perception, such as visual grouping. Of...

This paper describes the design, implementation and evaluation of lowcost motion capture systems with the support of hardwaresoftware interfaces for realtime automated simulation generation using CAD models. To capture the motions of 3D objects in a physical environment, stereo vision systems are developed using two kinds of inexpensive, offtheshelf cameras: 1) Wii Remote (Wiimote) and 2) Firef...

Computer generated 3D forms using generative procedures have matured in the last decade and now considered as a tangible approach for realizing architectural design ideas. As fascinating as the approach might be, it is still lacking actual application in the early architectural design process. There are many reasons for this, among them: it has many implications over the architectural design pr...

The Chinese traditional architecture called as DaMu structure, which wooden materials were used mainly. The work of historic heritage conservation needs the surveying maps and the 3D model of the building. Laser scanning techniques can provide the best potential for high efficient and more safety recording of the 3D data. Recently, Terrestrial Laser Scanning (TLS) has been used in some architec...

This paper describes a 3D scene analysis system that is capable of modelling real-world scenes, based on data acquired by a Laser Range Finder on board of a mobile robot. Laser range images directly provide access to three dimensional information, as opposed to intensity images. This characteristic makes range data suited to build 3D models of objects, and in general real world scenes. Results ...

Ten years ago the CAD Research Center at California Polytechnic University in San Luis Obispo, California identified a standard framework for agent-based, decision support systems. Employing inter-process and inference engine technologies of the time, the CAD Research Center termed this ‘blueprint’ the Integrated Collaborative Decision-Making (ICDM) framework. Over the past twelve years ICDM ha...
