summary	Shape grammar transformations have been used for developing new design styles by the systematic modification of grammars that encode existing styles. We make use of a style description scheme to aid grammar transformations for goal driven style change. A rule base was authored for the design of Greek temple facades, and was augmented with a style description scheme. These were tested at a student workshop wherein students were asked to develop grammars based on given style briefs. Results gained from the workshop confirmed that most students were able to assemble and transform grammars successfully. The method was found to be useful for teaching style and grammars to students and novice designers.

title	Readiness for the Use of Technology for effective learning via the vds: Case of the United Arab Emirates
source	Em‘body’ing Virtual Architecture: The Third International Conference of the Arab Society for Computer Aided Architectural Design (ASCAAD 2007), 28-30 November 2007, Alexandria, Egypt, pp. 439-456
summary	Review of the literature indicated that today’s knowledge-driven economy demands a workforce equipped with complex skills and attitudes such as problem solving, meta-cognitive skills, critical thinking and lifelong learning. Such skills can be acquired if learning and teaching are guided by the constructivist and cognitive learning theories. In particular, the constructivist approach emphasises effective learning processes based on learning by doing and collaboration. This approach is congruent with use of technologies, such as Virtual Design Studio (VDS), for the purpose of architecture education in design courses, but such use is lacking in the United Arab Emirates (UAE). It is thus important to assess the extent to which the constructivist and cognitive theories are implemented in teaching design courses in the Architecture schools of the UAE. It is also important to assess the effectiveness of employing technology in general and VDS in particular in implementing these theories. The author intends to study the relationship between effective learning on one hand and using VDS in implementing the constructivist and cognitive approaches on the other hand. Thus, the author conducted a preliminary study to gain a basic understanding of the difficulties, approaches, attitudes, perceptions, and motivation related to the learning of design in architecture schools in the UAE. Second, the investigation was designed to assess the extent to which the students would be interested in the use of sophisticated technology in the teaching and learning environment in the UAE architecture education schools in order to achieve effective learning. The study has been conducted in the United Arab Emirates University (UAEU). Methodology used for this was the focus group method. In addition to the focus group interviews with the UAEU students, unstructured individual interviews with lecturers from UAEU and the American University of Sharjah (AUS) have been carried out. Data analysis showed that students were not satisfied with the current teaching methods based on traditional lectures. It was concluded that students were ready to practice effective learning of design via the intermarriage of VDS and the constructivist and cognitive approaches. An ambiguity that remained was whether students were ready for assessment methods which are consistent with the constructivist approach.

title	Constructing Structural Shape Grammars
source	CAADRIA 2007 [Proceedings of the 12th International Conference on Computer Aided Architectural Design Research in Asia] Nanjing (China) 19-21 April 2007
doi	https://doi.org/10.52842/conf.caadria.2007.x.a9l
summary	Shape grammar has been shown to be a frame of work applicable to design issues in various fields. Almost all published grammars work only on the bottom level of shape replacement, however in practice, when using grammars to generate designs, the designer may work on different levels of abstractions, concerning about the hierarchy of the design as well. This suggests that, to make the generating process more coherent, the grammar itself need be able to work on different levels, too. This paper introduces the research work that aims at proposing a set of guidelines for writing shape grammar with which the designer could write structured shape grammars that will be easily automated for generating designs.

title	Mining a Collection of Animated Sketches

doi	https://doi.org/10.52842/conf.ecaade.2007.447
summary	How can we make a set of digital assets useful for teaching and research? As we amass data, it is crucial to select and interpret what is presented. This paper describes how a collection of animated drawings has been made accessible through an iterative development process. It describes a Web matrix interface, interpreted lesson formats and an assessment method. The assessment method of tallying achievement on design criteria before a lesson reveals inherent challenges of the problem, tallying afterwards reveals the effectiveness of the lesson in addressing those challenges. Using space-planning layout problems, we found that students readily picked up simple graphic devices such as measurement grids, adjacency diagrams and thumbnail sketches. Students showed less immediate improvement on skills that require juggling of multiple criteria, such as meeting all programmed area size requirements.

title	Visual-Physical Grammars
source	SIGraDi 2008 - [Proceedings of the 12th Iberoamerican Congress of Digital Graphics] La Habana - Cuba 1-5 December 2008
summary	This paper introduces new visual-physical design grammars for the design and manufacture of building assembly systems that provide visually rich, culturally resonant design variations for housing. The building systems are intended to be tailored for particular cultures and communities by incorporating vernacular, decorative design into the assembly design. Two complementary areas of computational design research are brought together in this work: shape grammars and digital fabrication. The visual or graphic aspects of the research are explored through shape grammars. The physical design and manufacturing aspects are explored through advanced digital design and fabrication technologies and, in particular, build on recent work on mono-material assemblies with interlocking components that can be fabricated with CNC machines and assembled easily by hand on-site (Sass, 2007). This paper describes the initial, proof-of-concept stage of this work: the development of an automated, visual-physical grammar for an assembly system based on a vernacular language of Greek meander designs. A shape grammar for the two-dimensional Greek meander language (Knight, 1986) was translated into a three-dimensional assembly system. The components of the system are uniquely designed, concrete “meander bricks” (Figure 1). The components have integrated alignment features so that they can be easily fitted and locked together manually without binding materials. Components interlock horizontally to form courses, and courses interlock vertically in different ways to produce a visual variety of meander walls. The assembly components were prototyped at desktop scale with a layered manufacturing machine to test their appearance after assembly and their potential for design variations (Figure 2). Components were then evaluated as full-scale concrete objects for satisfaction of physical constraints related to concrete forming and component strength. The automated grammar (computer program) for this system generates assembly design variations with complete CAD/CAM data for fabrication of components formed from layered, CNC cut molds. Using the grammar, a full-scale mockup of a corner wall section was constructed to assess the structural, material, and aesthetic feasibility of the system, as well as ease of assembly. The results of this study demonstrate clearly the potentials for embedding visual properties in structural systems. They provide the foundations for further work on assembly systems for complete houses and other small-scale structures, and grammars to generate them. In the long-term, this research will lead to new solutions for economical, easily manufactured housing which is especially critical in developing countries and for post-disaster environments. These new housing solutions will not only provide shelter but will also support important cultural values through the integration of familiar visual design features. The use of inexpensive, portable digital design and fabrication technologies will allow local communities to be active, cooperative participants in the design and construction of their homes. Beyond the specific context of housing, visual-physical grammars have the potential to positively impact design and manufacture of designed artifacts at many scales, and in many domains, particularly for artifacts where visual aesthetics need to be considered jointly with physical or material requirements and design customization or variation is important.

title	Various Media in the Design Process and Methodology
source	CAADRIA 2007 [Proceedings of the 12th International Conference on Computer Aided Architectural Design Research in Asia] Nanjing (China) 19-21 April 2007
doi	https://doi.org/10.52842/conf.caadria.2007.x.t8j
summary	The paper describes the mergence of traditional architectural design processes with approaches that rely on digital media and software for the creation of architectural space. The depicted projects are part of a ‘work in progress’ process, with a recent studio that is set up to apply the so far accumulated experiences. Within the projects, focus is on those design phases where the applied media and methodology is changed and where the back and forth between different media and the depth of their implementation is perceptible in, and / or has a significant influence on the design itself. Through a line of successive experiments, the paper explains the development of a possible method that utilizes a variety of today’s accessible tools in architecture, making use of phenomena that appear when changing from one tool to another. Goal is to avoid limitations that are existent by the solely employment of one media or method, and to understand the fusion between different media as an inspiring momentum to develop the design further. The paper draws a line from an initially experienced and analyzed design method over several projects in practice and academia to conclude with a possible design method that could be established successfully in both fields of architectural teaching and practice. Initial experiences had been drawn from professional practice, in which the digital realm was limited to a support device of the design process. The first project that is described in the paper, explored the employment of digital media as a possible tool to drive the design process in a broader sense. The studio setting was organized as a laboratory for the exploration of the change of applied media. Focus was on the influence on the design progress. The design method required of the studios participants was not exclusively based on an architectural program, but on an initial, very conceptual process with an artistic approach, based on personal experiences of each participant. This was meant to detach the students entirely from architectural processes and mindsets they had picked up so far. Parallel to that kind of an intellectual process, studio participants learned to handle Maya as the 3D modeling software of their choice. Both the technical knowledge and the artistic projects were merged in a second project phase, in which participants had to further develop their work by applying a very effective mix of various design tools. Using digital media as a parametric design generator, subsequent projects were developed. The task for the designers here were to decide what kind of algorithm could be applied to which process and when it was to be stopped for the best result. Applying such an automatism successfully to the design process, the employment of traditional media and methodology remained, to adapt the digital driven schemes to the required design task. The diverse design experiments demonstrate important aspects when merging complex design and animation software with traditional design processes. To achieve good architectural design results, all examined projects showed that traditional design methods with its physical models are hardly replaceable to its full extent by other media, but digital media are able to strengthen design processes and invite designers to explore new means of design work.

title	Teaching 3D Generative Virtual Architecture with VIPA CONSTRICTOR
source	Predicting the Future [25th eCAADe Conference Proceedings / ISBN 978-0-9541183-6-5] Frankfurt am Main (Germany) 26-29 September 2007, pp. 751-756
doi	https://doi.org/10.52842/conf.ecaade.2007.751
summary	CONSTRICTOR is a novel teaching and learning tool to introduce students of architecture to the fundamentals of computational design. It was developed within an EC funded e-learning project, VIPA (Virtual campus for virtual space design Provided for European Architects). In this paper, we describe the general structure and technology of CONSTRICTOR and its application within the course “Synthetic Constructions II”) that aims at familiarizing students with concepts like cellular automata, swarms, shape grammars, path finding etc. CONSTRICTOR allows students to observe simulations, navigate through them and change the parameters that define and control them, thereby developing an understanding for the rules that govern their virtual environments. They can also change the geometry used in the simulations and work with and export their results. Students can modify the simulations at code level, combine them or write entirely new simulations. Finally some of the student work performed during and after the course is described, and an outlook for future work and further developments around the VIPA courses and the constrictor software will be given.

doi	https://doi.org/10.52842/conf.acadia.2007.048
summary	Digital modeling in the design environment has prompted intuitive shaping of architectural form. The pliability of the imagination allows limitless possibilities of shape without a constrained methodology. This paper chronicles a design exploring catenary form-finding using parametric constraints in a dynamic modeling environment. Catenary structural networks are treated as digital cloth objects. Applying parametric edge and point constraints simulates various behavior patterns under gravity load. The integration of real-time Finite Element Method [FEM] and dynamic cloth simulation presents an intuitive method for the design and analysis of catenary structures. Constraints resist the limitless pliability of shape and hone the intuition using force to find form realized as a ceramic catenary network.

title	Automation of Passive Solar Design System
source	CAADRIA 2007 [Proceedings of the 12th International Conference on Computer Aided Architectural Design Research in Asia] Nanjing (China) 19-21 April 2007
doi	https://doi.org/10.52842/conf.caadria.2007.x.l5x
summary	This research, focus on the automation of passive solar design system using computational method. The quantitative nature of passive solar design system makes the automation possible. The automation is done in stages, because implementing the passive solar design system is not an isolated process, but intertwined with the overall design process. The first phase of automation concentrates in conceptual stage, to avoid major deviations in later stages of the design. The conceptual stage use Eco-grammar (A preset Design guidelines for corresponding climate) and user inputs for initial form generation. The second stage of automation is done after the user finalize the model with respect to its position rotation and arrangements. In this stage manipulation of vertex, edges and faces of the forms were manipulated using genetic algorithm. The value of mutation or crossover done in genetic algorithm is suggested by knowledge engine (preloaded design knowledge). Until the form obtains or reach closer to the desired values of performance the loop between analysis and mutation, crossover will be continued. On the basis of analysis result further manipulations may change from the previous which is guided by the knowledge engine.

title	Structuring a Generative Model for Urban Design: Linking GIS to Shape Grammars
source	Architecture in Computro [26th eCAADe Conference Proceedings / ISBN 978-0-9541183-7-2] Antwerpen (Belgium) 17-20 September 2008, pp. 929-938
doi	https://doi.org/10.52842/conf.ecaade.2008.929
summary	Urban Design processes need to adopt flexible and adaptive procedures to respond to the evolving demands of the contemporary city. To support such dynamic processes, a specific design methodology and a supporting tool are needed. This design methodology considers the development of a design system rather than a single design solution. It is based on patterns and shape grammars. The idea is to link the descriptions of each pattern to specific shape rules inducing the generation of formal solutions that satisfy the pattern. The methodology explores, from the urban designer point of view, the capacity of a shape grammar to codify and generate urban form (Duarte et al, 2007). This paper defines the ontology of urban entities to build on a GIS platform the topology describing the various components of the city structure. By choosing different sets of patterns the designer defines his vision for a specific context. The patterns are explicated into shape rules that encode the designer’s interpretation of the pattern, and operate on this ontology of urban entities generating solutions that satisfy the pattern’s concept. Some examples of the topological relations are shown.

summary	Negroponte (Negroponte 1969) described how the creative thinking of a designer can become affected by the ‘machine’ urging the designer to draw a distinction between ‘heuristics of form’ and ‘heuristics of method’. This ensured that by taking advantage of digital technology a symbiotic relationship was maintained between both of these. To date architects have investigated digital tools for generating form and imagery with increasing success, but have arguably fallen short of using those tools for advancing their design methods. The research presented here explores questions not solely focusing on the use of the tools, but on heuristic methods of the profession, to examine the interconnectiveness of the design method and the tool in a symbiotic fashion; to examine the nature of creativity. This paper is taking a critical standpoint about the place of digital tools in an architect’s method in the pursuit of poetic architecture and, in particular, its representation, to enable speculation, as opposed to prediction, of ideas in the design process from the early phases. The issue is discussed through the findings of my doctoral research case studies that have proved germane to my particular enquiry, that is, digital mediationbetween design ideation and design development.

doi	https://doi.org/10.52842/conf.caadria.2007.x.v8d
summary	In any built environment, there exist certain subtle stimuli that affect the occupants’ cognitive processes and performance. This research intends to identify: (1) what environmental stimuli an office building would generate that could affect the habitants’ cognitive ability, and (2) how the habitants react to these stimuli. The goals of the study are to develop a new method for using immersive virtual reality to represent a built environment for simulating environmental impact, and to discover factors that could influence habitants’ cognitive performance in a space. It is expected that the discoveries could advance the application of virtual reality to study human cognition in architecture.

summary	This project intends to develop a method for using virtual reality (VR) to represent a built environment for simulating environmental influences on occupants. Objectives of the project were to explore: (1) what environmental stimuli would affect habitants’ perception, and (2) what possible factors in the built environment would affect occupants’ cognition. An office was selected as the subject of study. Methods were to create a number of digital models, each containing an embedded variable, and then test the impact of environmental influences on visual perception. Results obtained in this study indicate that materials have stronger impact to human perception than colors, and VR has great potential for design decision making and post-occupancy evaluation.

title	Multi-touch - the future of design interaction
source	Computer Aided Architectural Design Futures 2011 [Proceedings of the 14th International Conference on Computer Aided Architectural Design Futures / ISBN 9782874561429] Liege (Belgium) 4-8 July 2011, pp. 557-572.
summary	The next major revolution for design is to bring the natural user interaction into design activities. Graphical User Interfaces (GUI) brought a new approach that was more effective compared to their conventional predecessors. In recent years, Natural User Interfaces (NUI) have advanced user experiences and multi-touch and gesture technologies provide new opportunities for a variety of potential uses in design. Much attention has been paid to leverage in the design of interactive interfaces. The mouse input and desktop screen metaphors limit the information sharing for multiple users and also delayed the direct interaction for communication between each other. This paper proposes the innovative method by integrating game engine ‘Unity3D’ with multi-touch tangible interfaces. Unity3D provides a game development tool as part of its application package that has been designed to let users to focus on creating new games. However, it does not limit the usage of area to design additional game scenarios since the benefits of Unity3D is allowing users to build 3D environments with its customizable and easy to use editor, graphical pipelines to openGL (http://unity3d.com/, 2010 ). It creates Virtual Reality (VR) environments which can simulates places in the real world, as well as the virtual environments helping architects and designers to vividly represent their design concepts through 3D visualizations, and interactive media installations in a detailed multi-sensory experience. Stereoscopic displays advanced their spatial ability while solving issues to design e.g. urban spaces. The paper presents how a multi-touch tabletop can be used for these design collaboration and communication tasks. By using natural gestures, designers can now communicate and share their ideas by manipulating the same reference simultaneously using their own input simultaneously. Further studies showed that 3Dl forms are perceived and understood more readily through haptic and proprioceptive perception of tangible representations than through visual representation alone (Gillet et al, 2005). Based on the authors’ framework presented at the last CAADFutures, the benefits of integrating 3D visualization and tactile sensory can be illustrated in this platform (Chen and Wang, 2009), For instance, more than one designer can manipulate the 3D geometry objects on tabletop directly and can communicate successfully their ideas freely without having to waiting for the next person response. It made the work more effective which increases the overall efficiency. Designers can also collect the real-time data by any change they make instantly. The possibilities of Uniy3D make designing very flexible and fun, it is deeply engaging and expressive. Furthermore, the unity3D is revolutionizing the game development industry, its breakthrough development platform for creating highly interactive 3D content on the web (http://unity3d.com/ , 2010) or similar to the interface of modern multimedia devices such as the iPhone, therefore it allows the designers to work remotely in a collaborative way to integrate the design process by using the individual mobile devices while interacting design in a common platform. In design activities, people create an external representation of a domain, often of their own ideas and understanding. This platform helps learners to make their ideas concrete and explicit, and once externalized, subsequently they reflect upon their work how well it sits the real situation. The paper demonstrates how this tabletop innovatively replaces the typical desktop metaphor. In summary, the paper addresses two major issues through samples of collaborative design: firstly presenting aspects of learners’ interactions with physical objects, whereby tangible interfaces enables them constructing expressive representations passively (Marshall, 2007), while focussing on other tasks; and secondly showing how this novel design tool allows designers to actively create constructions that might not be possible with conventional media.

title	Re-representation of Urban Imagery: Strategies for Constructing Knowledge
source	Expanding Bodies: Art • Cities• Environment [Proceedings of the 27th Annual Conference of the Association for Computer Aided Design in Architecture / ISBN 978-0-9780978-6-8] Halifax (Nova Scotia) 1-7 October 2007, 212-221

summary	Productive analysis of photographically composed urban imagery is a ‘wicked’ problem due to the presence of multiple, entangled systems. This paper proposes constructive analytic techniques for composite imagery, consisting of digitally generating and superimposing graphic overlaps within and adjacent to original images, producing new images not rationally related to nameable systems. These new images promote pattern identifi cation, which in turn has the potential to inform conclusions about memory and navigation in urban sites. Thus, the difficulty inherent in systemic urban analysis is shifted to one of abstract image interpretation, and a new set of refl ective strategies becomes relevant. These strategies are illustrated through analysis of two existing systems in a midsize, Midwestern city: a system of pedestrian walkways connecting several downtown buildings, and a system of overhead power distribution structures. The systems have observable characteristics in common. But, while the walkways represent a deliberate attempt to structure memory and thus to aid navigation, the system of power distribution structures makes no such claim. The paper discusses specific implications of the method informing the author’s ongoing research and architectural design teaching. In conclusion, wider implications are suggested, informing the general question of constructing urban knowledge.

summary	The research presented in this paper deals with the yet unexplored development of a constraint-based design strategy to support participatory housing planning processes in Latin America. The article discusses the implementation criteria of a constraint satisfaction approach to solving the building bulk design problem. This elementary problem to the architecture practice, is concerned with the synthesis of the boundary geometry from the volume, shape and allocation of the building and any part thereof located inside a given zoning lot. A legal solution to a building bulk design problem is a building cubature that complies with all the applicable bulk regulations. The case study applies to the common class of single-family house units produced in Chile and the regulatory framework implemented there. Two different computer implementation criteria are being tested in an ongoing series of trials. The first, and most extensively developed, makes use of Maxon’s XPresso® visual scripting environment to set up a semi-automated controllable design environment that allows to create parametric feature-based 3D models of building bulk solutions. The second approach is currently being tested by using Ilog’s OPL Studio® constraint programming environment to achieve fully automated search and 2D graphic visualization of the complete set of solutions to separate subdomains of the bulk problem.

summary	The goal of the research described in this paper is the formulation of a generative system for architectural design, where a structured core architectural idea is the input and alternatives to that idea are the output. Specifically we present a production pipeline of architectural / spatial configurations using the context of animation and time based design tools. Our model consists of “time” and space design constraints of boundaries / objects affecting a given architectural design, thus producing an alternative solution for every timeframe of the animation cycle. Initially the designer shapes an idea using animation software tools, where each tool is actually a constraint or a grammar rule defined informally by the user/designer. The influence of the tools can vary according to time, speed, location, configuration of the object and/or the constraint itself. In some of these animations the designer has the ability to sidestep partially the issue of emergence by providing specific key - frames for the solution to follow. The use of animation tools [shape driven curves, speed and time-line functions, parent child relationships] in the shape generation of our model empowers the user/designer to configure whole sets of shapes and designs interactively and without the need to define every solution independently. Simultaneously, a different, time-focused view of our model describes its use on designs that develop different configurations over time. Thus a duality of our model is established : the animated schema may be either a sum or a family of various designs or the animated time-line may represent a single design which changes over time. Finally the possibility of a structured graph representing each solution is discussed, where the designer can evaluate the merit of an individual solution in terms of conforming to the initial core idea or where alternative spatial configurations evolve in a different structure from the original design.
