summary	Brazil has so many historical cities with important architectural heritage. Some of them are remains of the colonial times and aggregate beautiful buildings such as, palaces, public buildings and churches in baroque style, legacy of the Portuguese colonization. Despite of its cultural value, most of these building sets are under several kinds of threats. This paper discusses about the experience on digital photogrammetric restitution of the building façades of Pelourinho, a neighborhood in the historical center of Salvador, the capital city of the State of Bahia. The architectural documentation is an important way to preserve and safeguard its memory, besides being an effective educational process about the meaning of preservation and cultural heritage.

title	Road hierarchy and speed limits in Brasília/Brazil
source	H.J.P. Timmermans, B. de Vries (eds.) 2008, Design & Decision Support Systems in Architecture and Urban Planning, ISBN 978-90-6814-173-3, University of Technology Eindhoven, published on CD
summary	This paper aims at exploring the theory of the Social Logic of Space or Space Syntax as a strategy to define parameters of road hierarchy and, if this use is found possible, to establish maximum speeds allowed in the transportation system of Brasília, the capital city of Brazil. Space Syntax – a theory developed by Hillier and Hanson (1984) – incorporates the space topological relationships, considering the city shape and its influence in the distribution of movements within the space. The theory’s axiality method – used in this study – analyses the accessibility to the street network relationships, by means of the system’s integration, one of its explicative variables in terms of copresence, or potential co-existence between the through-passing movements of people and vehicles (Hillier, 1996). One of the most used concepts of Space Syntax in the integration, which represents the potential flow generation in the road axes and is the focus of this paper. It is believed there is a strong correlation between urban space-form configuration and the way flows and movements are distributed in the city, considering nodes articulations and the topological location of segments and streets in the grid (Holanda, 2002; Medeiros, 2006). For urban transportation studies, traffic-related problems are often investigated and simulated by assignment models – well-established in traffic studies. Space Syntax, on the other hand, is a tool with few applications in transport (Barros, 2006; Barros et al, 2007), an area where configurational models are considered to present inconsistencies when used in transportation (cf. Cybis et al, 1996). Although this is true in some cases, it should not be generalized. Therefore, in order to simulate and evaluate Space Syntax for the traffic approach, the city of Brasília was used as a case study. The reason for the choice was the fact the capital of Brazil is a masterpiece of modern urban design and presents a unique urban layout based on an axial grid system considering several express and arterial long roads, each one with 3 to 6 lanes,

title	Virtual Reality Model of the Northern Sluice of the Ancient Dam in Marib/Yemen by Combination of Digital Photogrammetry and Terrestrial Laser Scanning for Archaeological Applications
source	International Journal of Architectural Computing vol. 5 - no. 2, pp. 340-354
summary	In this paper the potential of digital photogrammetry and terrestrial laser scanning in combination is demonstrated in the recording and 3D CAD construction of the northern sluice of the ancient dam in Marib/Yemen, which is located approx. 150 kilometre east of the capital city Sana'a, close to the inner Arabic desert. The Yemeni government proposed for initiation of the building into the list of the UNESCO world cultural heritage. This described project work is a co-operation between the Commission for Archaeology of Non-European Cultures (KAAK) Bonn of the German Archaeological Institute (DAI) and the department Geomatics of the HafenCity University Hamburg. The object recording was carried out in January 2006 with the digital SLR camera Fujifilm FinePix S2 pro and the terrestrial laser scanner Trimble GS100 during the archaeological excavations. The northern sluice was reconstructed and visualized as a computer-based 3D CAD model for archaeological investigations (as-builtdocumentation of the excavations) and for future tourism advertising and publication purposes.

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	Emerging Technololgy – Dilemma and Opportunities in Housing
source	CAADRIA 2007 [Proceedings of the 12th International Conference on Computer Aided Architectural Design Research in Asia] Nanjing (China) 19-21 April 2007

summary	Digital Technology has transformed industrial manufacturing and production; and an array of Industrial Design products provide increasing comfort and benefit to millions of global citizens via ergonomic and mass production/customization strategies. Yet, housing needs of a rapidly growing global population are rarely affected by digital technology. Shifts in societal demographics, from rural to urban city centres, and concurrently Global Warming and ecological changes are exacerbating the world housing situation. Millions are homeless, live in inadequate shelter, or as in the US Manufactured Housing (MH) market, live in nondurable poor quality “manufactured” houses that are detrimental to health, at best, or during extreme weather events, suffer catastrophic damages often resulting in death to occupants. Nevertheless, housing concepts and related living units have benefited very little when compared to architecture’s related manufacturing industries counter-parts (i.e. automotive, aerospace, marine industries, etc). While Technology has vividly expanded the shape language of architecture (i.e. Free-Form-Design), some may argue that Free-Form- Design buildings generally have beauty that is only “skin deep” and typically focus on providing signature statements for both the designer and elite clientele. In this paper, we will briefly review the role of the architect in the US Manufactured Housing industry; additionally, we will identify the major problems that plaque the US Manufactured Housing Industry. Further, we will review how architects and Industrial Designers use technology in their respective fields and draw larger designmanufacture principals for issues of global housing. Our findings and analysis suggest that an Industrial Design approach, applied in architecture for mass housing, offers a means of improving the architect’s role and technology in manufactured housing for the masses.

title	Technological language x scientific language: Structuring educational speeches for the area of digital graphics [Lenguaje tecnológico vs. lenguaje científico: Estructurando discursos educacionales para la gráfica digital]
source	SIGraDi 2007 - [Proceedings of the 11th Iberoamerican Congress of Digital Graphics] México D.F. - México 23-25 October 2007, pp. 141-145
summary	This work looks to contribute to the structuring of educational speeches able to promote the use of the virtual space like laboratory for the simulation of the phenomenon of interaction between light and matter in different levels of similarity with the reality. The computer resources available for that present a technological specific language, mixing proceedings heuristics and physical. This demands of the students a detailed control of parameters, which need to be recognized and associated to the scientific knowledge. You being adopted “concept maps”, like strategy of attendance of processes of teaching / apprenticeship, these associations are set out, supplying sufficient elements to prepare, to revise and to enlarge the speeches open to question.

title	Open-source, parametric architecture to propagate hyper-dense, sustainable urban communities: parametric urban dwellings for the experience economy
source	Proceedings of the 15th International Conference on Computer Aided Architectural Design Research in Asia / Hong Kong 7-10 April 2010, pp. 443-452
doi	https://doi.org/10.52842/conf.caadria.2010.443
summary	Rapid developments in societal, technological, and natural systems suggest profound changes ahead if research in panarchical systems (Holling, 2001) is to be believed. Panarchy suggests that systems, both natural and man-made, rise to the point of vulnerability then fail due to disruptive forces in a process of ‘creative destruction.’ This sequence allows for radical, and often unpredictable, renewal. Pressing sustainability concerns, burgeoning urban growth, and emergent ‘green manufacturing’ laws, suggest that future urban dwellings are headed toward Gladwell’s ‘tipping point’ (2002). Hyper-dense, sustainable, urban communities that employ open-source standards, parametric software, and web-based configurators are the new frontier for venerable visions. Open-source standards will permit the design, manufacture, and sale of highly diverse, inter-operable components to create compact urban living environments that are technologically sophisticated, sustainable, and mobile. These mass-customised dwellings, akin to branded consumer goods, will address previous shortcomings for prefabricated, mobile dwellings by stimulating consumer desire in ways that extend the arguments of both Joseph Pine (1992) and Anna Klingman (2007). Arguments presented by authors Makimoto and Manners (1997) – which assert that the adoption of digital and mobile technologies will create large-scale societal shifts – will be extended with several solutions proposed.

title	Three dimensional isovist analysis method [Método de Análisis Tridimensional con isovistas]
source	SIGraDi 2007 - [Proceedings of the 11th Iberoamerican Congress of Digital Graphics] México D.F. - México 23-25 October 2007, pp. 174-176
summary	This paper presents a three dimensional method of isovist analysis implemented in the MaxScript programming language. The script accepts as its input a standard three dimensional model of the buildings and terrain being analyzed, upon which a N×N grid is projected. Each square of this grid is assigned a height value, thereby producing a simplified surface description which is amenable to mathematical analysis. A three dimensional isovist is then generated for each grid square, by placing an observation point 1.5 meters above its center and finding the intersection of a series of rays from this point to the input model. The distance from the observation point to the intersection is summed over for all the angles studied giving a compound isovist measurement for the grid square under consideration.

title	Analysis of Design Support for Kinetic Structures
source	Vienna University of Technology; Building Science & Technology
summary	This thesis attempts the formation and systemization of a basis of knowledge and information, which is indispensable to turn a design support for kinetic structures into representation by means of a 3d animating program. Representation of kinetic structures by means of the existing ordinary software sources is possible; Nevertheless, such representation lacks of different important features and functions and results eventually in the total absence of a real model of the construction, which is valuable to the user of the program especially in the field of the kinetics, where everything depends on the movement: design not only requires, but demands for visualisation. A personal interest in kinetic architecture and therefore in the physical movement of structural elements in a building, as well as an attempt to “fathom” the possibility of changing this concept to visualization and modern reality by the use of a software are the main incentives of this master thesis. First, a general research will be performed in order to check the existence of similar or semisimilar proposals. The area in which the research will be held is the Bibliography in kinetic architecture and parametric design. A comparison of animation and 3D prototype software in well-known programs will focus on whether virtual weather conditions are considered as a parameter to the animation of the structure of the programs and case studies of several existing kinetic structures will be performed, in order to point out flaws and/or helpful commands in the programs in connection with the presentation of kinetic architecture. Criteria for the choice of the software: ability to customise and to produce geometric modelling, animation in relation to time (video animation) and the simulation after taking into consideration weather factors. Finally, using the computer and the scripting language, based probably on the theory of parametric design and primitive instancing, a realistic simulation of different elements will be performed in relation to variable measurements of luminance, ventilation and temperature so as to render feasible the construction of a whole structure. The results of the thesis will be used in the future as the basic knowledge in the creation of software for simulation of kinetic architecture. This program will be used as a tool for the architect to present a building, where kinetic architecture will be applied and to create simulation of the kinetic movement through a library of the existing prefabricated elements which will be created with the help of this thesis.

title	A Study of Light/Darkness in Sacred Settings: Digital Simulations
source	International Journal of Architectural Computing vol. 5 - no. 3, pp. 507-521
summary	Studying light/darkness and sacred architecture reveals that the "holy" light dramatizes the spiritual state and affects the mood of the user in the sacred space. Furthermore, it shows that faith dictates the treatment of light/darkness in the sacred setting as means to enhance the spiritual experience. These two premises were investigated by conducting digital daylight simulations on the Brihadeshvara Hindu Temple (1010 AD) of Tanjore, Tamilnadu, India. This sacred monument, listed as one of UNESCO's World Heritage Sites, is an intriguing case study since the treatment of the 'holy light' in the temple is actually the treatment of the 'holy darkness'. The simulated values were compared to the Illuminating Engineering Society (IES) standards. The results demonstrate that digitized simulations can illustrate the significance of light/darkness in sacred settings as a spiritual experience. Moreover, this quantitative investigation can augment the qualitative studies in the field of historic sacred architecture. The work presented here unites and extends some previously published work.

title	Computational Design Solutions in architectural education: The use of script language to design complex surfaces [Solución de problemas relacionados al diseño de superficies complejas: Experiencia de programación en la educación del arquitecto]
source	SIGraDi 2007 - [Proceedings of the 11th Iberoamerican Congress of Digital Graphics] México D.F. - México 23-25 October 2007, pp. 97-101
summary	In this paper, the author explains why architects who know how to use scripts have an advantage over the ones who just know how to manipulate a specific software. The reason behind this affirmation is that knowing how to program frees the architect from the rules and language of the interactive software. To prove his point, the author organized two workshops where students at the school of architecture learned to use Rhinoscript. The students didn't create a new interface, but used an existing one. They adapted the program (Rhino) to a design problem they had formulated at the beginning of the workshop. Students could have also used MaxScript (3DS Max) and MelScript (Maya).

title	Surface-driven architecture: Moving Beyond the Ornament/Structure Opposition
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. 671-682
summary	Contemporary architecture has been influenced by a shift of interest from the dialectic Derridean theories of language to those of Deleuze and Guattari who put more emphasis on transitions, experimentation and material presence. New digital design tools as well as new construction materials have opened up more possibilities for architects. E-paper, digital screens, printed concrete, composite polymers and dynamic cladding systems, have allowed designers to relish architecture at the surface level. Moreover, the process of architectural design is shifting from the desktop to the virtual world of the computer. NURBS, Blobs, Metaforms, Isomorphic Surfaces and other complex geometries are now possible using surface-driven computer modelling software. Because of this, the resultant architecture display a much more distinct appreciation and mastery of surface-effects. The following article argues that contemporary architecture is becoming increasingly a process of surfacing, both as a process of revealing and as a process of concealing. Surface, in common parlance, is generally understood as the exterior boundary of things, the outer skin of any object. In this sense, surfaces are actual, material, textural entities that we often encounter first. The surface is also taken to be something that conceals: “it was not what it appeared to be on the surface.” However, it is when things surface that they become evident or apparent; they appear out of a previously concealed existence or latency. Thus, surfacing is a process of becoming explicit, of becoming experientially apparent in a movement from virtuality to actuality. This article argues that the use of emerging computer technologies in architecture, have resulted in a renewed prioritization of surface and surface-effects. It shall be concluded that the surface-driven nature of most contemporary modelling software has resulted in a new approach to architectural design, one that has the potential of subverting the traditional hierarchy between ornament and structure. As a result, this design strategy has allowed for a much more spirited and creative approach to architecture.

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	CONVERSION OF GPS DATA TO CARTESIAN COORDINATES VIA AN APPLICATION DEVELOPMENT ADAPTED TO A CAD MODELLING SYSTEM
source	2nd International Conference on Experiments/Process/System Modelling/Simulation & Optimization (2nd IC-EpsMsO), Athens, 4-7 July, 2007
summary	Nowadays, common methodologies in telegeoprocessing–telegeomonitoring use telecommunication means such as the GPS in order to transmit geographical coordinates to modelling and simulation systems. These 3D geodetic coordinates (φ, λ, h) can be used by modeling systems via specifics interfaces in order to proceed to real-time modelling of the remotely transmitted data. A previous published work describes a real-time remote 3D digitizing and modelling procedure via transmitted Global Positioning System (GPS) data from the field towards to a CAD system. However, these GPS data must be converted to adequate coordinate’s format (x, y, z) so that the CAD system can use them. This paper presents the computing development of a specific application adapted to a CAD modelling system permitting the conversion of the geodetic coordinates to cartesian coordinates. It presents the relation between geodetic and cartesian coordinates, the options of the final developed application and finally some schematic aspects of the computing process. The application development is realized in AutoCAD modelling system environment via special developed interface in Visual Basic (VBA) and Visual Lisp programming language. The aim of this work is to give the possibility to a CAD modelling system to “translate” and receive automatically geographical coordinates or to convert manually and selectively geodetic coordinates φ, λ, h to cartesian coordinates x, y, z.

title	Sketch-based Methods for Researching Building Layouts through the Semantic Fingerprint of Architecture
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. 85-102.
summary	The paper focuses on the early stages of the design process where the architect needs assistance in finding reference projects and describes different aspects of a concept for retrieving previous design solutions with similar layout characteristics. Such references are typically used to see how others have solved a similar architectural problem or simply for inspiration. Current electronic search methods use textual information rather than graphical information. The configuration of space and the relations between rooms are hard to represent using keywords, in fact transforming these spatial configurations into verbally expressed typologies tends to result in unclear and often imprecise descriptions of architecture. Nowadays, modern IT-technologies lead to fundamental changes during the process of designing buildings. Digital representations of architecture require suitable approaches to the storage, indexing and management of information as well as adequate retrieval methods. Traditionally planning information is represented in the form of floor plans, elevations, sections and textual descriptions. State of the art digital representations include renderings, computer aided design (CAD) and semantic information like Building Information Modelling (BIM) including 2D and 3D file formats such as Industry Foundation Classes (IFC) (IAI, 2010). In the paper, we examine the development of IT-technologies in the area of case-based reasoning (Richter et al., 2007) to provide a sketch-based submission and retrieval system for publishing and researching building layouts including their manipulation and subsequent use. The user interface focuses on specifying space and their relations by drawing them. This query style supports the spatial thinking approach that architects use, who often have a visual representation in mind without being able to provide an accurate description of the spatial configuration. The semantic fingerprint proposed by (Langenhan, 2008) is a description and query language for creating an index of floor plans to store meta-data about architecture, which can be used as signature for retrieving reference projects. The functional spaces, such as living room or kitchen and the relation among on another, are used to create a fingerprint. Furthermore, we propose a visual sketch-based interface (Weber et al., 2010) based on the Touch&Write paradigm (Liwicki et al., 2010) for the submission and the retrieval phase. During the submission process the architect is sketching the space-boundaries, space relations and functional coherence's. Using state of the art document analysis techniques, the architects are supported offering an automatic detection of room boundaries and their physical relations. During the retrieval the application will interpret the sketches of the architect and find reference projects based on a similarity based search utilizing the semantic fingerprint. By recommending reference projects, architects will be able to reuse collective experience which match the current requirements. The way of performing a search using a sketch as a query is a new way of thinking and working. The retrieval of 3D models based on a sketched shape are already realized in several domains. We already propose a step further, using the semantics of a spatial configuration. Observing the design process of buildings reveals that the initial design phase serves as the foundation for the quality of the later outcome. The sketch-based approach to access valuable information using the semantic fingerprint enables the user to digitally capture knowledge about architecture, to recover and reuse it in common-sense. Furthermore, automatically analysed fingerprints can put forward both commonly used as well as best practice projects. It will be possible to rate architecture according to the fingerprint of a building.

summary	In a simple communication model we must talk about the understanding between participants. This is the result of a continuing connection and a dialog of agreements and disagreements in order to arrive at sharing an idea. However, society today is in an evolutionary lapse at an accelerated pace that interjects itself in this process. It is here where social forces distend and generate important ruptures between generations and individuals that fight to prevail or impose new languages and lifestyles. Today's society has become a visual society whose effect has been reinforced through technology in the devices that we use on a daily basis. The daily use of technology and its new languages has marked a disconnection between individuals that must be closed by using a new acculturation and teaching models. Disconnection is a omnipresent modern phenomenon that can be felt as the main effect in what specialists call the digital gap. This gap not only separates generations, but also ideologies with respect to the form in which we perceive, transmit and teach in our society today. This disconnection can be easily understood through a school system that has been designed for a manufacturing and agricultural world. However, many sectors within our society have been in state of constant change and evolution. This situation generates many opportunities where an agile society is required in response to these new local and global challenges. The students of today have, for example, multi-tasking abilities that better assimilate these changes. The researchers, Ian Jukes and Anita Dosaj refer to this disconnection as the result of poor communication between digital natives (our present-day students) and digital immigrants (many present-day adults). This phenomenon results in the fact that parents and educators speak the digital dialect as a second language, and because of that are lacking in their models of communication. For example, digital natives prefer a variety of sources with rapid access, while the digital immigrants prefer slower, more controlled sources that are limited and regulated. Nowadays, our educational or production activities in which we find ourselves immersed on a daily basis cause us to participate in a wide range of processes of production, dissemination and analysis of visual forms as part of our final product or service. Much of the work that we elaborate in movies, video and photography explore meaning, perception and communication in context as well as anthropological and ethnographic themes. Using this framework for our society today, the importance of the search for the promotion of the study of visual representation and the media for the greatest development and generation of benefits is brought to the fore. Through the use of images we can describe, analyze, communicate and interpret human behavior. All these settings, full of digital disconnections and reencounters, impact on all the visual aspects of culture, including art, architecture and material objects, influencing the bodily expressions of human beings. We have created a visual society when we put emphasis on the meaning and interpretation of all we receive through our visual sense. Wherever we look, we find objects that have been modified beyond their primary function to communicate messages. In this ecosystem we are consumers and suppliers. The communication and research needed to achieve reconnection, as well as the creation of new forms of production and visual understanding, are the themes on which the works contained in this edition are centered.

title	Applying generative modeling procedure to explore architectural forms

summary	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 process mainly the practicality of design during the conceptual design stage; it is cumbersome to develop construction drawings for complex architectural forms; and the necessity for producing conceptual designs quickly in less time as design requirements and decisions are constantly being changed. This paper initially reports on a practical development of a computer program which generates architectural massing designs based on integrating forms generation technique in a design scheme. The influence for this development was inspired by Spirolaterals technique used in generating complex 3D architectural forms that are based on parametric shape configuration. The development has three goals: to review the principles for constructing generative forms in the conceptual design stage using simple CAD tools, to assist in the production of design schemes based on a few basic shapes and rules, and to explore 3D forms finding and generation without the need to write a complicated computer program that are difficult to produce by hand. The development resulted in generating an interesting number of 3D compositions. The author applied this technique to experiment during the production of a design scheme. The paper hence describes the current development of ArchiGen tool to produces generative 3D forms utilizing ArchiCAD © GDL programming language. The tool is embedded within ArchiCAD for generating 3D shapes. One of the main features of this implementation is that users are able to sketch 2D shapes and the tool will deform its three dimensional generation. Moreover, the user being able to abstract the architectural character from the resulting complex 3D shapes. This development extends current related work by allowing the designer to load shapes into ArchiGen which acts as vocabulary of shapes for a design scheme constraints. It is intended from this work to inspire future work focusing on using generative tools in the early conceptual design stages.
