title	CAD-based path planning for 3-D line laser scanning
source	Computer-Aided Design, Vol. 31 (7) (1999) pp. 473-479
summary	The problem of path planning for 3-D line laser scanning is addressed in this article. The path under study is for a line, as opposed to a point in conventional CNC and CMMtoolpath planning. While the objective of the latter case is to drive a point along a curve, that of the former case is to drive a line across a surface. To solve this problem, a pathplanning method is developed. First, a slicing approach is put forward to divide a part CAD model into a number of sections, since the laser scanning line is limited by thescanning width and a single scanning pass cannot cover the whole surface. Second, for each section, a scanning pass is generated to cover the section surface. To ensure amaximum coverage for each section, the surface profile is determined, and the top of the scanning window is set along the upper boundary of the surface profile. Third,combination of scanning all the sections forms a complete scan of a surface. It is shown that with the proposed method a 3-D line laser scanning process can be effectivelyautomated.

title	Towards a Multi-Agent System for Network Decision Analysis
source	CAADRIA '99 [Proceedings of The Fourth Conference on Computer Aided Architectural Design Research in Asia / ISBN 7-5439-1233-3] Shanghai (China) 5-7 May 1999, pp. 373-382

summary	We introduce the outline of a multi-agent system that can be used for network decision analysis. This system is based on cellular automata and multi-agent technology. The system simulates how agents move around in a particular 3D (or 2D) environment, in which space is represented as a lattice of cells. Agents represent objects or people with their own behavior, moving over the network. We think that the system provides a potentially valuable tool to support design and decision-making processes, related to user behavior, in architecture and urban planning.

title	The Use of New Media Tools n Environmental Simulation
source	Simulation of Architectural Space - Color and Light, Methods and Effects [Proceedings of the 4rd European Architectural Endoscopy Association Conference / ISBN 3-86005-267-5] Dresden (Germany), 29 September - 1 October 1999, pp. 28-31
summary	We propose a new application in environmental simulation using digital techniques and new media tools, namely QuickTimeVirtualReality (QTVR) and QuickTimeMovies (QTMovies). QTVR enables the user to interactively rotate in a 360degree panorama. The QTVR panoramas will be generated from single images taken with analogue endoscopic simulation techniques by using special QTVR software. The different QTVR panoramas of the model can be connected with each other, additionally by integrating QTMovies showing tracking shots from one panorama node to the other. Thus a virtual net from the planned urban place can be built in which the user can interactively move around and explore. Practical use of this application in public participation in urban development is proposed. A simple demoversion of the here described application will be shown at the EAEA 1999.

title	xWORLDS, the implementation of a three-dimensional collaborative sketch tool within the context of a third year design course
source	International Conference on Generative Art
summary	This work is the result of a postgraduate thesis done at the chair for Architecture and CAAD at the ETH in Zurich Switzerland. It proposes a prototype for a three-dimensional modelling tool in a networked environment. The work is composed of two distinct parts. (1) A modeling tool to create three-dimensional objects in an intuitive and interactive manner. (2) A database component to store and retrieve the objects. This modeller has been implemented for the first time in a design course, where students where using the modeller to sketch and interact within a large group to formulate aspects of their design. The Paper focuses on the modeller and on the experience from a one week workshop.1. Modelling Tool. The modeling tool operates in two different modes: (A). Composing cubic forms within a limited cubic space. (B). Deforming the composition of boxes by means of their interaction with a separate volume. For the composition of cubes, the user has to drag a cube with the mouse to continue placing cubes in space. Furthermore, he can move and delete the placed cubes. Simple and complex objects can be created this way, in an easy and intuitive manner. For the second mode, the forms are generated by intersecting a volume with an object created previously in the first mode. The volume can be scaled and moved. The part of the existing object located outside the volume remains unchanged, while the part that lies inside it is transformed in the same way as the volume. Complex forms can be created in this way with simple transformations. 2. Database Storage and Retrieval.The created objects can be stored in a database. Other users can access the objects stored in the database and continue working on them in the same modeling environment. There are two ways to interact with objects from the database. On one side it is possible to substitute the composition of cubes, and keep the distorted framestructure of the currently active object unchanged. On the other side it is possible to initiate a morphing process between the currently active framestructure and the framestructure of an object from the database. This process can be stopped at any time. It is always possible to switch back in the modeling modus and continue work on the object.3. Workshop at the the School of Design at the Hong Kong Polytechnic University.A Group of over 100 students were using the tool in a second year design course. The tool has been implemented as part of a workshop in the second half of the design studio. The workshop lasted for one week in which a collective dataset of over 1000 models has been created by the students. Afterwards, a possibility was given to the students to retrieve models from the database and to process them in different software packages or have them physically built by a 3D printer, and then continue working on the physical model.

title	An approach for the interoperation of web-distributed applications with a design model
source	Automation in Construction 8 (3) (1999) pp. 291-303
summary	This paper defines the data and inference requirements for the integration of analysis applications with a product model described by a CAD/CAE application. Application input conditions often require sets of complex data that may be considered views of a product model database. We introduce a method that is compatible with the STEP and PLIB product description standards to define an intermediate model that selects, extracts, and validates views of information from a product model to serve as input for an engineering CAD/CAE application. The intermediate model framework was built and tested in a software prototype, the Internet Broker for Engineering Services (IBES). The first research case for IBES integrates applications that specify certain components, for example pumps and valves, with a CAD/CAE application. This paper therefore explores a sub-set of the general problem of integrating product data semantics between various engineering applications. The IBES integration method provides support for a general set of services that effectively assist interpretation and validate information from a product model for an engineering purpose. Such methods can enable application interoperation for the automation of typical engineering tasks, such as component specification and procurement.

title	Design Simulation
source	CAADRIA '99 [Proceedings of The Fourth Conference on Computer Aided Architectural Design Research in Asia / ISBN 7-5439-1233-3] Shanghai (China) 5-7 May 1999, pp. 243-252
doi	https://doi.org/10.52842/conf.caadria.1999.243
summary	This paper intends to explore methods of constructing a design simulator. Two methodologies, approached differently, imitate the human design processes. The first component is an algorithmic method which has a cognitive model embedded. This cognitive model hypothesizes that human design has certain design logic applied. The design rationales are based on knowledge stored in a designer_ memory. Each time a similar design task is encountered, the same design procedures will be repeated for completion. What makes the results different are the design information used and sequences of processing it. A kitchen design using procedural algorithms is developed to simulate this design aspect. The second component simulates an intuitive design approach. Intuition is defined as design by rules of thumb, or heuristic design. This study investigated how to simulate an intuitive design process. The method involves building up a set of inductive rules symbolizing cultural aspects that need to be addressed in a design. A residential foyer design is the simulation task. The driving force is the heuristics. Results in this study have shown that there are many variables to include but impossible to capture and simulate any of the design processes, which are the reasons why studies in this area are difficult.

summary	The senses of “Touch” bring people the feeling of reality, and human beings can always naturally sense the tactile impression. Hence we touch things and our sense tells us that our hands are touching something (Hinckley et al. 1999). Comparing to the tools used by designers between traditional and new digital media in the design process, the most difference is in the sense of touch. This paper focuses on the sense of touch to point out the haptic experience which have ignored by the past in design process. Four phenomena will be discussed in details and some useful suggestions given for future study.

title	The right tool at the right time : investigation of freehand drawing as an interface to knowledge based design tools
source	College of Architecture, Georgia Institute of Technology
summary	Designers use different symbols and configurations in their drawings to explore alternatives and to communicate with each other. For example, when thinking about spatial arrangements, they draw bubble diagrams; when thinking about natural lighting, they draw a sun symbol and light rays. Given the connection between drawings and thinking, one should be able infer design intentions from a drawing and ultimately use such inferences to program a computer to understand our drawings. This dissertation reports findings from empirical studies on drawings and explores the possibility of using the computer to automatically infer designer's concerns from the drawings a designer makes. This dissertation consists of three parts: 1) a literature review of design studies, cognitive studies of drawing and computational sketch systems, and a set of pilot projects; 2) empirical studies of diagramming design intentions and a design drawing experiment; and 3) the implementation of a prototype system called Right-Tool-Right-Time. The main goal is to find out what is in design drawings that a computer program should be able to recognize and support. Experiments were conducted to study the relation between drawing conventions and the design tasks with which they are associated. It was found from the experiments that designers use certain symbols and configurations when thinking about certain design concerns. When thinking about allocating objects or spaces with a required dimensions, designers wrote down numbers beside the drawing to reason xviii about size and to calculate dimensions. When thinking about visual analysis, designers drew sight lines from a view point on a floor plan. Based on the recognition that it is possible to associate symbols and spatial arrangements in a drawing with a designer's intention, or task context, the second goal is to find out whether a computer can be programed to recognize these drawing conventions. Given an inferred intention and context, a program should be able to activate appropriate design tools automatically. For example, concerns about visual analysis can activate a visual simulation program, and number calculations can activate a calculator. The Right- Tool-Right-Time prototype program demonstrates how a freehand sketching system that infers intentions would support the automatic activation of different design tools based on a designers' drawing acts.

title	A database supporting evolutionary product model development for design
source	Automation in Construction 8 (3) (1999) pp. 305-323
summary	This paper presents the facilities in the EDM-2 product modeling and database language that support model evolution. It reviews the need for model evolution as a system and/or language requirement to support product modeling. Four types of model evolution are considered: (1) translation between distinct models, (2) deriving views from a central model, (3) modification of an existing model, and (4) model evolution based on writable views associated with each application. While the facilities described support all for types of evolution, the last type is emphasized. The language based modeling capabilities described in EDM-2 include: (a) mapping facilities for defining derivations and views within a single model or between different models; (b) procedural language capabilities supporting model addition, deletion and modification; (c) support for object instance migration so as to partition the set of class instances into multiple classes; (d) support for managing practical deletion of portions of a model; (e) explicit specification and automatic management of integrity between a building model and various views. The rationale and language features, and in some cases, the implementation strategy for the features, are presented.

source	ACADIA Quarterly, vol. 18, no. 2, pp. 18-21
doi	https://doi.org/10.52842/conf.acadia.1999.018.2
summary	Unique to the interior design program at Cornell University is a planned pedagogical approach requiring equal emphasis toward manual and digital graphic communication at the freshman level. Prior to 1998, computer-based instruction only occurred at the junior year of study. Recognizing that cultural and symbolic biases against digital media were formally being instituted by curriculum policy, faculty searched for a new perspective. Central to success was the removal of illogically placed boundaries, both mental and physical. In response, students are now encouraged to cultivate a fluid dexterity between traditional and digital methods, at times using various skills concurrently for design analysis and representation (Figures 1, 2, 3, 4, 5, 6, 7). Course content for DEA115 ranges from basic orthographic drafting, paraline projection, and perspective drawing to color rendering and composition. Students utilize a full range of media: pencil, ink, marker, pastel, AutoCAD, 3DS/ MAX, and Photoshop in this graphics studio. Course meetings total six contact hours per week, constituting a three credit hour class. Assignments are purposefully created to shatter digital myths. For example, instead of a standard, rote drafting exercise, AutoCAD is used to explore design ideas through systemic object manipulation (Figures 8, 9).

summary	Internet-based project extranets represent a new generation of CAD tools that has been much talked about in the design professions recently. Many believe they hold considerable promise to change dramatically how design participants collaborate in the AEC industry. Yet we are only beginning to understand the real value that such project extranets provide. Clearly, empirical studies of project extranet usage are needed to illuminate the situation. This paper summarizes the results of an explorative study into the implications of such project extranets on design collaboration.

summary	The VR-DIS research programme aims at the development of a Virtual Reality – Design Information System. This is a design and decision support system for collaborative design that provides a VR interface for the interaction with both the geometric representation of a design and the non-geometric information concerning the design throughout the design process. The major part of the research programme focuses on early stages of design. The programme is carried out by a large number of researchers from a variety of disciplines in the domain of construction and architecture, including architectural design, building physics, structural design, construction management, etc.Management of design information is at the core of this design and decision support system. Much effort in the development of the system has been and still is dedicated to the underlying theory for information management and its implementation in an Application Programming Interface (API) that the various modules of the system use. The theory is based on a so-called Feature-based modelling approach and is described in the PhD thesis by [first author, 1999] and in [first author et al., 2000a]. This information modelling approach provides three major capabilities: (1) it allows for extensibility of conceptual schemas, which is used to enable a designer to define new typologies to model with; (2) it supports sharing of conceptual schemas, called type-libraries; and (3) it provides a high level of flexibility that offers the designer the opportunity to easily reuse design information and to model information constructs that are not foreseen in any existing typologies. The latter aspect involves the capability to expand information entities in a model with relationships and properties that are not typologically defined but applicable to a particular design situation only; this helps the designer to represent the actual design concepts more accurately.The functional design of the information modelling system is based on a three-layered framework. In the bottom layer, the actual design data is stored in so-called Feature Instances. The middle layer defines the typologies of these instances in so-called Feature Types. The top layer is called the meta-layer because it provides the class definitions for both the Types layer and the Instances layer; both Feature Types and Feature Instances are objects of the classes defined in the top layer. This top layer ensures that types can be defined on the fly and that instances can be created from these types, as well as expanded with non-typological properties and relationships while still conforming to the information structures laid out in the meta-layer.The VR-DIS system consists of a growing number of modules for different kinds of functionality in relation with the design task. These modules access the design information through the API that implements the meta-layer of the framework. This API has previously been implemented using an Object-Oriented Database (OODB), but this implementation had a number of disadvantages. The dependency of the OODB, a commercial software library, was considered the most problematic. Not only are licenses of the OODB library rather expensive, also the fact that this library is not common technology that can easily be shared among a wide range of applications, including existing applications, reduces its suitability for a system with the aforementioned specifications. In addition, the OODB approach required a relatively large effort to implement the desired functionality. It lacked adequate support to generate unique identifications for worldwide information sources that were understandable for human interpretation. This strongly limited the capabilities of the system to share conceptual schemas.The approach that is currently being implemented for the core of the VR-DIS system is based on eXtensible Markup Language (XML). Rather than implementing the meta-layer of the framework into classes of Feature Types and Feature Instances, this level of meta-definitions is provided in a document type definition (DTD). The DTD is complemented with a set of rules that are implemented into a parser API, based on the Document Object Model (DOM). The advantages of the XML approach for the modelling framework are immediate. Type-libraries distributed through Internet are now supported through the mechanisms of namespaces and XLink. The implementation of the API is no longer dependent of a particular database system. This provides much more flexibility in the implementation of the various modules of the VR-DIS system. Being based on the (supposed to become) standard of XML the implementation is much more versatile in its future usage, specifically in a distributed, Internet-based environment.These immediate advantages of the XML approach opened the door to a wide range of applications that are and will be developed on top of the VR-DIS core. Examples of these are the VR-based 3D sketching module [VR-DIS ref., 2000]; the VR-based information-modelling tool that allows the management and manipulation of information models for design in a VR environment [VR-DIS ref., 2000]; and a design-knowledge capturing module that is now under development [first author et al., 2000a and 2000b]. The latter module aims to assist the designer in the recognition and utilisation of existing and new typologies in a design situation. The replacement of the OODB implementation of the API by the XML implementation enables these modules to use distributed Feature databases through Internet, without many changes to their own code, and without the loss of the flexibility and extensibility of conceptual schemas that are implemented as part of the API. Research in the near future will result in Internet-based applications that support designers in the utilisation of distributed libraries of product-information, design-knowledge, case-bases, etc.The paper roughly follows the outline of the abstract, starting with an introduction to the VR-DIS project, its objectives, and the developed theory of the Feature-modelling framework that forms the core of it. It briefly discusses the necessity of schema evolution, flexibility and extensibility of conceptual schemas, and how these capabilities have been addressed in the framework. The major part of the paper describes how the previously mentioned aspects of the framework are implemented in the XML-based approach, providing details on the so-called meta-layer, its definition in the DTD, and the parser rules that complement it. The impact of the XML approach on the functionality of the VR-DIS modules and the system as a whole is demonstrated by a discussion of these modules and scenarios of their usage for design tasks. The paper is concluded with an overview of future work on the sharing of Internet-based design information and design knowledge.

summary	This paper presents a case study of the application of computer techniques for design communication and visual impact analysis. We were sponsored by China Light & Power Company Ltd. To simulate the design of a proposed electricity substation and its it is setting in a residential neighborhood. During a five-week intensive study, we took nearly one thousand photographs of the existing site. We also created a three-dimensional CAD model of the proposed substation, and produced perspectives from points of view analogous to the photographs. We applied Apple Quicktime VR technology to document the site environment with 360-degree panoramas. We then montaged the computer-generated panoramas with those taken from the real environment. A navigable virtual environment, architectural animation and set of still images were presented to the public in September 1998. The reactions from the regional council members and local residents nearby were recorded to provide evidence to measure the effectiveness of digital architectural design communication.

summary	In this paper, we discuss about the architectural design collaboration and information management based on the worldwide network. Internet and WWW are rapidly infiltrating through the architectural schools in the world, so it is easy to communicate and share the design information with web homepage and e-mail. But, a set of homepage and e-mail is not sufficient for easy and smooth design. Because of the data management method and system for network collaboration is not yet well organized nor well developed. In this paper, we report the results of two Virtual Design Studio projects that we have experienced and intend to analyze the problems to exchange and share the design information on the web. Then we propose the collaborative design system environment and evaluate it from the result of the experimental third Virtual Design Studio project that we have executed.

title	CAD in Practice Profile: Polshek Partnership Architects LLP
source	ACADIA Quarterly, vol. 18, no. 3, pp. 10-14
doi	https://doi.org/10.52842/conf.acadia.1999.010
summary	Since the advent of computers for architecture, James Stewart Polshek, FAIA, founding partner of Polshek Partnership Architects LLP, has insisted that his firm's technology standards match the same high level they maintain for their awardwinning designs. As explained by Senior Associate Don Weinreich, AIA, this objective translates into computing priorities that differ significantly from those of the average firm. Weinreich observes that many "typical" firms use computer technology for profitability first, consistency of documentation second, and enhancement of the design process last. At Polshek Partnership these priorities are reversed. Supporting and enriching the design process is the overriding objective of all computing activity at the firm. Consistency of documentation, as a second-level priority, is pursued not just for routine coordination and quality control, but in a proactive effort to maintain control over every detail in the process of communicating design intent—in other words, to further support design. The potential to increase profitability through computerization (e.g., by doing the same work in less time) ranks low among the computing priorities at Polshek Partnership. According to Weinreich, "the guiding principle is to do no harm," that is, to exploit the maximum potential of computers to support the design process without incurring additional net costs. In effect, the firm is taking the time and effort that computerization can save on many routine, procedural tasks and reinvesting those savings in additional design studies and details. This approach to computers for design is consistent with that of other AIA Firm Award-winning practices profiled in this series. (1)(2)

title	Generative Polymodal Music Process
source	International Conference on Generative Art
summary	We present underlying ideas used to develop an Algorithmic Composition software named KYKLOS. It was designed to generate music based on generalised musical scales and modes. It is an interactive sonic device to be applied in composition as well in performance. The sonic output of the whole process can be described as generalised polymodal music since “synthetic scales” are generated by the algorithm. This environment can be used in a Computer Assisted Composition manner in order to generate MIDI files. On the other hand, it can equally be used as a performance environment in which a dynamic change of parameters enables a real time control of the sonic process. Recently, we advocated that several mathematical applications in Computer Music can be understood as Sound Functors [1]. In extension, we describe here a sound functor used to model scales and modes. As can be verified, part of early investigations on mathematical structures in music studied musical scales and modes using Combinatorics, Fibonacci Series and Golden Mean in order to understand compositional processes which use modal concepts. Using the Functor definition it is possible to enumerate n-scales as a sequence of integers. Each value in that sequence gives the distance (in half tones) between two consecutive tones. For example, the sequence 3:2:2:3 is interpreted as a pentatonic scale C-Eb-F-G-Bb, and as defined above it is a C mode. So, if we apply cyclical permutations, (n-1)-sequences of numbers should be interpreted as n-modes of tones. Our algorithmic implementation is described briefly. A n-mode is defined as an array with n-1 integers [a1, a2, ...an-1]. Each array generated at k-th step can be read as a number a1a2a3 ....an-1 in decimal representation, where ai is a integer between 1 and 9. We denote the number obtained at k-th step as (a1a2a3 ...an-1)(k) . The rules to implement the algorithm are the following:1) V0 = (1, 1, 1, 1 ......,1) (initial n-mode)2) ? ai ? 11 with i= 1, 2...n-1 (octave range constraint)3) Vk = (a1a2a3 ...an-1)(k) < (b1b2b3 ...bn-1)(k+1) = Vk+1 where aj ?bj , 1? j ? n-1.4) Vmax = (13 – n, 1, 1, ...,1)In this paper we start with a theoretical view and an introduction on the algorithmic mechanism used. Further, we present a concept of man ? machine interaction used to create the composition environment. We also describe the compositional graphic interface developed and general functions of the system. Finally there is a set of music examples generated by KYKLOS as MIDI files.

title	Full-scale Modeling and the Simulation of Light
source	Proceedings of the 7th European Full-scale Modeling Association Conference / ISBN 3-85437-167-5 / Florence (Italy) 18-20 February 1999, 100 p.
summary	EFA ‘ 99 covered the use of light throughout 1:1 simulation. As a rule the field of light design has a closer relation with simulation in true scale. Therefore, it is surprising that a conference dealing with this field did not take place at an earlier stage which might be due to the differing approaches concerning implementation and working focus at the various laboratories. The remarkable achievements of the individual lighting companies on the market regarding research work seem very promising and necessarily are to be duly acknowledged also on the part of academic circles. Furthermore, a productive exchange of information might develop between the, somewhat incompatibly seeming, interest groups. More interaction would surely prove wise, as the stage for successful research work in the field of light design and light impact is only to be set by combining all strengths.

title	Baking Light: Global Illumination in VR Environments as architectural design tool

summary	As proven in the past, immersive Virtual Environments can be helpful in the process of architectural design (Achten et al. 1999). But still years later, these systems are not common in the architectural design process, neither in architectural education nor in professional work. The reasons might be the high price of e.g. CAVEs, the lack of intuitive navigation and design tools in those environments, the absence of useful and easy to handle design workflows, and the quality constraints of real-time display of 3D models. A great potential for VR in the architectural workflow is the review of design decisions: Display quality, comfortable navigation and realistic illumination are crucial ingredients here. Light is one of the principal elements in architectural design, so design reviews must enable the architect to judge the quality of his design in this respect. Realistic light simulations, e.g. via radiosity algorithms, are no longer the domain of high-end graphic workstations. Today's off-the-shelf hardware and 3D-software provide the architect with high-quality tools to simulate physically correct light distributions. But the quality and impression of light is hard to judge from looking at still renderings. In collaboration with the Institute of Computer Graphics at our university we have established a series of regular design reviews in their immersive virtual environment. This paper describes the workflow that has emerged from this collaboration, the tools that were developed and used, and our practical experiences with global-light-simulations. We share results which we think are helpful to others, and we highlight areas where further research is necessary.

title	Animation and Multimedia: Interviews at Five Large Los Angeles Firms
source	ACADIA Quarterly, vol. 18, no. 3, pp. 1-3
doi	https://doi.org/10.52842/conf.acadia.1999.001
summary	Developments in digital media have created a myriad of tools to help architects communicate ideas. Three dimensional graphics software has revolutionized our ability to visualize our ideas. With the advent of animation and advanced methods of real time video presentation seem to have substantially upgraded the architects' tool chest. Significant advances have been made recently in bringing animation capabilities to the architectural desktop. To discover the level of integration of animation and multimedia in architectural firms, a series of interviews were conducted at five large Los Angeles firms. The interviews were structured with open-ended questions to allow the firms to emphasize their interests and capabilities. This document depicts the status of the current thinking at Gensler, Jerde, NBBJ, RTKL, and DMJM.
