title	Towards a natural and appropriate Architectural Virtual Reality: the nAVRgate project. Past, present, future
source	Proceedings of the Ninth International Conference on Computer Aided Architectural Design Futures [ISBN 0-7923-7023-6] Eindhoven, 8-11 July 2001, pp. 139-149
summary	The lure of virtual environments is strong and the apparent potential is enticing. But questions of how Human Computer Interaction (HCI) issues should be handled and married with best practice in Human-Human Interaction (HHI) remains largely unresolved. How should architectural images and ideas be most appropriately represented, and how should designers interact and react through this computer mediated medium? Whilst there is never likely to be unanimity in answer to such questions, we can develop new ideas and new systems, test them, report on them and invite comment. The nature and novelty of virtual environments is such that refinements and innovations are likely to come from a variety of sources and in a variety of ways. The work described here explains the evolution and current plans for the development of a particular approach that has been developed and refined by the authors. Low-cost, effective and appropriate are the key words that have driven the developments behind the evolving nAVRgate system that has arisen from this work, and that is described here.

title	Interfaces for Virtual Environments; A Review Recent Developments and Potential Ways forward
doi	https://doi.org/10.52842/conf.ecaade.2000.215
source	Promise and Reality: State of the Art versus State of Practice in Computing for the Design and Planning Process [18th eCAADe Conference Proceedings / ISBN 0-9523687-6-5] Weimar (Germany) 22-24 June 2000, pp. 215-219
summary	The physical and visual nature of the interface devices and media that enable the human agent to interact with a virtual world have evolved over the past few years. In this paper we consider the different lines of development that have taken place in the refinement of these interfaces and summarise what has been learned about the appropriate nature of the interface for such interaction. In terms of the physical aspects we report on the kind of devices that have been used to enable the human agent to operate within the computer generated environment. We point out the successes and failures in the systems that have been tried out in recent years. Likewise we consider the kinds of software generated interface that have been used to represent virtual worlds. Again, we review the efficacy of the environments that have been devised; the quality of the Cyberplace. Our aim is to be able to comment on the effectiveness of the systems that have been devised from a number of points of view. We consider the physical and software-based aids for navigation; the nature of the representation of architectural worlds; strengthening “groundedness”; the inclusion of “otherness”; and reinforcement of the idea of “presence”

title	NAVRgate X, A Naturalistic Navigation Metaphor for Large Scale Virtual Environments
doi	https://doi.org/10.52842/conf.caadria.2003.625

title	Towards Naturalistic Navigation Metaphors for large scale Virtual Environments
source	SIGraDi’2000 - Construindo (n)o espacio digital (constructing the digital Space) [4th SIGRADI Conference Proceedings / ISBN 85-88027-02-X] Rio de Janeiro (Brazil) 25-28 september 2000, pp. 247-250
summary	This paper looks at the background to the development of alternative interfaces to Virtual Environments and suggests a reappraisal of some of the early work which allowed a sense of presence in the ‚real’ world. Initial work, the virtual exercise bike, is appraised, and new work is described which further develops the development of a low-cost interface system. Work in progress is described which is a combination of hard- and software. The solution described is a ‚hands free’ interface enabling the user to experience a VE in a similar manner to a physical environment, using movements of the head and feet for navigation. Whilst this is possible using expensive, proprietary equipment, the presented solution concentrates on a low cost approach. In line with this, the system uses a low cost gaming environment which is described and evaluated.

title	Applications in architectural design and education and practice
source	Report for the NSF/MIT Workshop on Shape Computation, Cambridge, Mass., 25-26 April 1999
summary	Shortly after shape grammars were invented by Stiny and Gips, a two part project for shape grammars was outlined by Stiny. In a 1976 paper,1 Stiny described "two exercises in formal composition". These simple exercises became the foundation for the many applications of shape grammars that followed, and suggested the potential of such applications in education and practice. The first exercise showed how shape grammars could be used in original composition, that is, the creation of new design languages or styles from scratch. The second exercise showed how shape grammars could be used to analyze known or existing design languages. Both exercises illustrated the unique characteristics of the shape grammar formalism that helped motivate a quarter century (almost!) of shape grammar work. General but simple, formal yet intuitive: qualities that continue to make shape grammar disciples and confound skeptics. The history of shape grammar applications in architecture and the arts for the two complementary purposes of synthesis and analysis, as well as for a third, joint purpose is sketched in the first section of this report. These three categories of applications do not have rigid boundaries. They are used in this report mostly as a framework for discussion. An overview of the roles of shape grammar applications in education and practice is given in the second section. New and ongoing issues concerning shape grammars in education and practice are discussed in the last section.

summary	My work is research focused. Broadly speaking, I’m interested in the “How” of creative production, as opposed to the “What”. I ask “How is this?” not “What is this?” I am interested in “How” designs and things are made or become, in the processes or paths to form, whether abstract or material. As a process carried out over time, computation offers a unique means for understanding and describing the “How” of design and making. I explore this potential with shape grammars and, most recently, with making grammars. The unique visual and spatial nature of the rules and computations of these grammars is aimed at unveiling the “How” in design.

title	Designing with Grammars
source	Computer Aided Architectural Design Futures: Education, Research, Applications [CAAD Futures ‘91 Conference Proceedings / ISBN 3-528-08821-4] Zürich (Switzerland), July 1991, pp. 33-48
summary	Shape grammars that generate languages of designs have been used widely over the past several years to describe and understand a diversity of architectural and other styles of designs. These grammars have been developed to address two fundamental concerns in design: 1) the analysis of contemporary or historic styles of designs, and 2) the synthesis or creation of completely new and original styles of designs. Most applications of shape grammars so far have been concerned with analysis. The creative use of shape grammars - the use of grammars to invent new architectural or other designs - has not been exploited nearly as well. A new series of exercises for designing with shape grammars, and also with color grammars, is sketched informally here. These exercises are currently being used in classes in the Architecture and Urban Design Program at U.C.L.A.

title	Transformations of Languages of Designs
source	University of California, Graduate School of Architecture and Urban PIanning, Los Angeles
summary	Stylistic change and innovation is a central and traditional issue in art and architecture. In this study, a formal model is developed for representing stylistic change. Styles are defined in terms of rule-based systems called shape grammars that generate languages of designs. Changes in styles are represented as transformations of the shape grammars that define these styles. The model is first sketched informally and considered in relation to other, traditional approaches to style and change. It is then presented in detail and illustrated with numerous simple examples. Last, the model is applied to describe actual, historical examples of stylistic transformations: one in the decorative arts, one in the fine arts, and one in architecture.

title	Photogrammetry as an aid to lighting design for industrial interiors
doi	https://doi.org/10.52842/conf.ecaade.2002.494
source	Connecting the Real and the Virtual - design e-ducation [20th eCAADe Conference Proceedings / ISBN 0-9541183-0-8] Warsaw (Poland) 18-20 September 2002, pp. 494-501
summary	Photogrammetry methods have been shown to be useful as a tool for investigation of illuminance distribution and light losses in interiors containing obstruction configurations that approximate to simple rectilinear objects. This work examines the use of photogrammetry to model obstructions having a greater degree of complexity and a case study demonstrates the applicability of the technique to lighting design for a factory. The results confirm that this technology would accelerate the process of incorporating the effect of obstructions in routine lighting analysis and design.

title	Languages of Designs : from Known to New
source	Environment and Planning B. 1981. vol. 8: pp. 213-238 : ill. includes bibliography
summary	A procedure for defining new languages of designs from known or given ones is presented. It is specified in terms of shape equivalence rules or shape equivalence rule schemata which allow shapes in spatial relations given or inferred from existing design languages to be replaced with other shapes. The new spatial relations so defined can be used to determine a wide variety of new, original languages of designs. The possibility of using shape equivalence rules or rule schemata for characterizing formal compositional aspects of historic styles or languages of designs and relationships between them is also discussed

title	The Concept of a Meta-Font
source	Visible Language. Winter, 1982. vol. XVI: pp. 3-27 : ill. includes bibliography
summary	A single drawing of a single letter reveals only a small part of what was in the designer's mind when that letter was drawn. But when precise instructions are given about how to make such a drawing, the intelligence of that letter can be captured in a way that permits us to obtain an infinite variety of related letters from the same specification. Instead of merely describing a single letter, such instructions explain how that letter would change its shape if other parameters of the design were changed. Thus an entire font of letters and other symbols can be specified so that each character adapts itself to varying conditions in an appropriate way. Initial experiments with a precise language for pen motions suggest strongly that the font designer of the future should not simply design isolated alphabets; the challenge will be to explain exactly how each design should adapt itself gracefully to a wide range of changes in the specification. This paper gives examples of a meta-font and explains the changeable parameters in its design

title	Digital tea house: Japanese tea ceremony as a pretext for exploring parametric design and digital fabrication in architectural education
doi	https://doi.org/10.52842/conf.caadria.2011.071
source	Proceedings of the 16th International Conference on Computer Aided Architectural Design Research in Asia / The University of Newcastle, Australia 27-29 April 2011, pp. 71-80
summary	This paper reviews the Digital Tea House, a joint workshop in August of 2010 held at the University of Tokyo, Department of Architecture, together with Columbia University GSAPP. Three pavilions for hosting ceremony were designed and built in less than one month, in an attempt to bridge technology and culture not only through design but also fabrication. Issues addressed in the process included applications of computational design, interpretations of tradition and culture in spatial or activity oriented expressions, structural stability, to practical solutions for quick physical materialization. Three teams comprised of 6 to 8 students, each a blend of different nationalities, ultimately produced 3 full-scale tea houses with the same software, primary material, budget, and principal fabrication method.

title	Irregular Vertex Editing and Pattern Design on Mesh
doi	https://doi.org/10.52842/conf.acadia.2011.278
source	ACADIA 11: Integration through Computation [Proceedings of the 31st Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA)] [ISBN 978-1-6136-4595-6] Banff (Alberta) 13-16 October, 2011, pp. 278-283
summary	This paper introduces an innovative computational design tool used to edit architectural geometry by addressing the problem of irregular vertices. An irregular vertex is a special kind of vertex which is connected with fewer or greater less or more edges than regular vertices on a mesh object. Irregular vertices create problems with further surface rationalization, as well as structural analysis and constructability of the surface. Geometry created using other tools can also be remeshed upon import. Using the developed tool, the user is able to identify irregular vertices, interactively change the type, and then move or remove these irregular vertices. Additionally, a computational tool to make various design patterns on the mesh after the topology has been edited is also developed. The workflow is illustrated step by step in the pipeline. The advantages and disadvantages of editing mesh topology on architectural geometry design including the limitations are discussed at the end.

title	Rapid SmartCode Modeling - Procedural Modeling for Urban Environments
source	SIGraDi 2009 - Proceedings of the 13th Congress of the Iberoamerican Society of Digital Graphics, Sao Paulo, Brazil, November 16-18, 2009
summary	This paper presents an image-driven method to rapidly generate 3D digital urban models for presentation in a real-time Virtual Reality (VR) environment. Several computational tools and methods are developed in order to give the end user the ability to transform a single 2D image into a realistically textured and rendered a 3D urban model. Using this method, city models based on SmartCode, a template for planning and urban design, are generated and presented in a VR visualization tool. The methods to generate VR city models including inputs, process, output, and pipeline are explained. One generated 3D city model is demonstrated in the results section.
