summary	The development of better User Interface (UI) and Tangible User Interface (TUI) for 3D modeling has lasted for decades. With the popularity of free form style achieved by algorithmic methods, the existing solutions of UI/TUI for CAD are gradually insufficient. Neglecting the steep learning curve of algorithmic design requiring solid background of mathematics and programming, the common drawback is the lack of interactivity. All actions rely heavily on mental translations and experimental trial and error. In this research, we try to realize the idea of interactive algorithmic design by developing a tangible calligraphic brush, with this device designer can intuitively adopt algorithmic methodology to achieve highly creative results.

title	The Use of the Smart Geometry through Various Design Processes: Using the programming platform (parametric features) and generative components
source	Digitizing Architecture: Formalization and Content [4th International Conference Proceedings of the Arab Society for Computer Aided Architectural Design (ASCAAD 2009) / ISBN 978-99901-06-77-0], Manama (Kingdom of Bahrain), 11-12 May 2009, pp. 297-304
summary	The emergence of parametric generative design tools and prototyping manufacturing technology led to radical changes in architectural morphologies. This change increased the opportunity to develop innovative smart geometries. Integrating these algorithms in the parametric softwares led to variations in building design concepts increasing alternatives and decreasing the repetitive work previously needed in conventional CAD software. The chosen software in this research is Generative Components (GC). It is a software design tool for an associative and parametric design platform. It is tested for using Global Variables with associative functions during the concept creation and form GC comprises features. The results presented in this research may be considered an introduction to the smart geometry revolution. It deals with the generative design which applied in the design process from conceptual design phase, defining the problem, exploring design solutions, then how to develop the design phases. Office building is a building type which encourages new forms that needs computational processes to deal with repetitive functions and modular spaces and enclosed in a flexible creative structural skin. Generative design helps the office buildings to be arranged, analysed, and optimized using parameters in early stages in design process. By the end of the research, the use of the smart geometry in a high rise office building is defined and explained. The research is divided into three parts, first a summary of the basic theories of office buildings design and the sustainable requirements that affect it, and should be integrated. Secondly, the previous experiences in generating office buildings by Norman foster and Sergio Araya. At last, a case study is proposed to test and evaluate the use of the parametric generative methodology in designing an office building with specific emphasis on the function, environmental aspects and form generation using Generative Components (GC) Software.

title	Visual Programming in Architecture: Should Architects Be Trained As Programmers?
source	T. Tidafi and T. Dorta (eds) Joining Languages Cultures and Visions: CAADFutures 2009 CD-Rom
summary	Most commercial CAAD applications have online communities of end users, through blogs, discussion forums and learning portals. On many occasions, questions lead to the conclusion that the software can only provide the desired functionality using scripting or programming, to fill in the gaps of the software feature set. However, more than once, people suggest that architects are not programmers and that they should not be responsible for adding this functionality. Similarly, when guiding students through some of their technical design studio problems, a comparable reaction is noticed. This is especially remarkable, considering the fact that these students had prior programming courses, as part of their Bachelor of Architecture curriculum.

summary	The connection between biological systems and machines is quickly becoming an important factor in designing the built environment. This paper explores the model of abstraction languages as a method to create communications between biological and mechanical systems, focusing on modes accessible to design professionals. The development of data and control abstraction in programming is explored in order to develop linkages between physical systems and digital interfaces. This examination looks at current methods of data conveyance for the built environment, and at pushing beyond these current methods to suggest a method of abstraction. The researchers are particularly interested in the ability of abstraction to compress ecological/biological complexity into accessible modules for responsive environments.

title	Making use of 3D programming to document and enhance an architectural vocabulary: Case study dealing with artefacts of the Canadian built heritage
source	T. Tidafi and T. Dorta (eds) Joining Languages, Cultures and Visions: CAADFutures 2009, PUM, 2009, pp. 133-142
summary	This paper examines the objectives and describes the methodology of an ongoing research project concerned with the built heritage of Montreal, Canada; more precisely, with the openings (doors, windows, bow-windows, dormers, etc.) in residential buildings. Within the framework of this project, we aim to implement digital environments to document and enhance the architectural vocabulary of openings. We adopt 3D programming to describe the way in which the artefacts are assembled from different components. The aim of this process is to enable the introduction of variations into the principles governing the composition of the artefacts, so as to generate new configurations.

title	Programming framework for architectural design ANAR+: Object oriented geometry
source	T. Tidafi and T. Dorta (eds) Joining Languages, Cultures and Visions: CAADFutures 2009, PUM, 2009, pp. 771- 785
summary	From the recent advent of scripting tools integrated into commercial CAAD software and everyday design practice, the use of programming applied to an architectural design process becomes a necessary field of study. The presented research explores the use of programming as explorative and reflexive medium (Schön, 1983) through the development of a programming framework for architectural design. Based on Java, the ANAR+ library is a parametric geometry environment meant to be used as programming interface by designers. Form exploration strategies based on parametric variations depend on the internal logic description, a key role for form generation. In most commercial CAD software, geometric data structures are often predefined objects, thus constraining the form exploration, whereas digital architectural research and teaching are in need for an encompassing tool able to step beyond new software products limitations.

source	SIGraDi 2009 - Proceedings of the 13th Congress of the Iberoamerican Society of Digital Graphics, Sao Paulo, Brazil, November 16-18, 2009
summary	The aim of this paper is the discussion of aspects like accident and programming in the creative process in Media Art As a transdisciplinary and collaborative activity, it could be seen as a possibility for knowledge construction and sharing spaces. It also shows how media art practice can be used as a reference for the creative process in the architectural field. Building knowledge spaces through creative processes is a challenge based on the latest reconfiguration of the relations among artists, artworks and observers, which were enhanced after digital technology. Designing knowledge space as collaborative process, we assume that our examination contribute to any field by stimulating the transitions from analog to digital culture.

title	Teaching Systems-Thinking with Algorithmic Process: Introduction to computation and programming with processing programming language
source	Digitizing Architecture: Formalization and Content [4th International Conference Proceedings of the Arab Society for Computer Aided Architectural Design (ASCAAD 2009) / ISBN 978-99901-06-77-0], Manama (Kingdom of Bahrain), 11-12 May 2009, pp. 37-46
summary	This research investigates how algorithm design and scripting as pedagogy can affect generalized design ability and understanding. Logical, systematic thinking is considered foundational in developing architectural design aptitude and is explicit when designing algorithms. The course work presented mandates the construction of process rather than product. Scripting is implemented not as a means to an end but rather a medium for exploration. More valuable than formal generator or problem-solver, these scripted designs test direct aesthetic implications. Further tested is the role of animation in de-linearizing the design process. By isolating the algorithm as topic, technique, and concept, scripting skills and the produced artifact are extendable and are translatable to other media. Algorithm design is presented as a 2-dimensional but temporal endeavor: students script an animate, interactive vector-based image. This facilitates the transition from algorithm to spatial experience while also readying students for form-based explorations. The 2-d temporal exercise is of a similar order of complexity to a 3-dimensional static condition. Pieces of the animation structure are provided as a canvas, specifically the ability of the viewer to manually control a single parametric variable that affects the visual output through a user-interface element. The following and final project of the course expands upon the technique of scripting image in the design of an experience by collaging video, images and animation.

title	Ivy: Bringing a Weighted-Mesh Representations to Bear on Generative Architectural Design Applications
doi	https://doi.org/10.52842/conf.acadia.2016.140
source	ACADIA // 2016: POSTHUMAN FRONTIERS: Data, Designers, and Cognitive Machines [Proceedings of the 36th Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) ISBN 978-0-692-77095-5] Ann Arbor 27-29 October, 2016, pp. 140-151
summary	Mesh segmentation has become an important and well-researched topic in computational geometry in recent years (Agathos et al. 2008). As a result, a number of new approaches have been developed that have led to innovations in a diverse set of problems in computer graphics (CG) (Sharmir 2008). Specifically, a range of effective methods for the division of a mesh have recently been proposed, including by K-means (Shlafman et al. 2002), graph cuts (Golovinskiy and Funkhouser 2008; Katz and Tal 2003), hierarchical clustering (Garland et al. 2001; Gelfand and Guibas 2004; Golovinskiy and Funkhouser 2008), primitive fitting (Athene et al. 2004), random walks (Lai et al.), core extraction (Katz et al.) tubular multi-scale analysis (Mortara et al. 2004), spectral clustering (Liu and Zhang 2004), and critical point analysis (Lin et al. 20070, all of which depend upon a weighted graph representation, typically the dual of a given mesh (Sharmir 2008). While these approaches have been proven effective within the narrowly defined domains of application for which they have been developed (Chen 2009), they have not been brought to bear on wider classes of problems in fields outside of CG, specifically on problems relevant to generative architectural design. Given the widespread use of meshes and the utility of segmentation in GAD, by surveying the relevant and recently matured approaches to mesh segmentation in CG that share a common representation of the mesh dual, this paper identifies and takes steps to address a heretofore unrealized transfer of technology that would resolve a missed opportunity for both subject areas. Meshes are often employed by architectural designers for purposes that are distinct from and present a unique set of requirements in relation to similar applications that have enjoyed more focused study in computer science. This paper presents a survey of similar applications, including thin-sheet fabrication (Mitani and Suzuki 2004), rendering optimization (Garland et al. 2001), 3D mesh compression (Taubin et al. 1998), morphin (Shapira et al. 2008) and mesh simplification (Kalvin and Taylor 1996), and distinguish the requirements of these applications from those presented by GAD, including non-refinement in advance of the constraining of mesh geometry to planar-quad faces, and the ability to address a diversity of mesh features that may or may not be preserved. Following this survey of existing approaches and unmet needs, the authors assert that if a generalized framework for working with graph representations of meshes is developed, allowing for the interactive adjustment of edge weights, then the recent developments in mesh segmentation may be better brought to bear on GAD problems. This paper presents work toward the development of just such a framework, implemented as a plug-in for the visual programming environment Grasshopper.

title	Source Studio: Teaching Programming For Architectural Design
source	T. Tidafi and T. Dorta (eds) Joining Languages Cultures and Visions: CAADFutures 2009 CD-Rom
summary	The architectural studio framework presented here is based on the use of programming as central form generation reflexive medium (Schon, 1983). Its aim is to teach architectural design while introducing a different approach toward computer tools by enabling students to fully explore variations in their designs through the use of coding for form definition. It proposes the students to reflect on their design process through its confrontation to algorithmic formalization (Mitchell 1990). This results in exercising the synthetic re-thinking of their initial sketch intents to comply with the difficult task of fitting the language syntax. With the proliferation and constant replacement of computer tools among the architectural practice, a shift appears in the attitude towards introducing students to different tools: studio teaching is branded by specific software platforms advocated by the teaching team. A lack of generalized view, independent of commercial CAD software, is problematic for the definition of new teaching tools suited for this constantly evolving situation (Terzidis, 2006).

title	Collective Intelligence: An Agent-Based Approach to Programmatic Organization in Architecture
source	International Journal of Architectural Computing vol. 7 - no. 3, 479-499
summary	Architectural programming is the research and decision-making process that identifies the scope of work to be designed. Programming is difficult because it involves identifying, collecting, analyzing and updating information from different sources such as engineers, clients, users, consultants, and others. In this paper I propose a computational model for programming and describe its implementation, a tool called PENA that allows a programming expert to represent different processes and people involved in a project using intelligent agents. By delegating responsibility to agents, a programming expert can better organize and manage project data as well as find creative solutions to conflicting issues through agent negotiation. As a proof-of-concept, I show how an agent, called the Arch-Learner, manages adjacencies of rooms in a simple program for a house by clustering them into public and private rooms. I conclude with a discussion of future work and development of PENA.

summary	Acoustics are important performance criteria for architecture; however, architects rarely consider them, except, perhaps, when designing concert halls. Architectural spaces can be said to perform well or poorly in terms of their acoustic qualities. By altering the geometry or material characteristics of the surfaces within a room in specific ways, the acoustics can be controlled. Once the geometric rules governing these acoustic alterations are understood, these rules can be encoded into a CAD system through parametric modeling or the use of computer programming. The architectural designer can then generate acoustically regulating surfaces according to desired performance criteria. In this way, acoustic engineering links to architectural design, and allows architectural design to become acoustically performance-driven. This paper considers three primary types of acoustic surfaces: absorbers, resonators, and diffusers. complex surfaces that combine these three performance characteristics in different ways are proposed.

summary	Logic and evolution in ontogenetic processes for Architectural design was the title for a summer program taught at the Escuela de Arquitectura of the Universidad Anahuac from June to July 2008 in the State of Mexico, Mexico. Every single result in architectural design follows logical steps enclosed in the design processes. These logical processes evolve through space-time sequences in order to generate a diversity of possible solutions. In Biology an ontogenetic process refers to the development of an individual organism, anatomical or behavioral feature from the earliest stage to maturity. Following this development criteria students were encouraged to understand the main logics of natural and physical systems through the aid of computer programming. These logics must be understood as tridimensional geometries digitally generated. Right from the beginning all processes generated during the explorations and investigations had to be visualized as integral design performances. The integral design system must embedded structure, function, form and material capacities through the aid of computer programming, digital fabrication technologies and material assembling techniques. It is important to note that final prototypes had to demonstrate the diversity of capacities of the whole system in order to automate the components in evolution.

summary	In recent years a number of projects have been emerged, in which the new possibilities of the computer as a design tool, have been used. Through the digital chain from design to manufacturing the efficiency has increased and allows the implementation of complex architectural structures. With all these new opportunities, also new challenges arise in the teaching and the educational concepts. The paper describes the detailed course concept and the didactic strategy using the example of a parametric designed roof structure, we designed, planed and build up in scale 1:1 within the main course. „Wendepunkt\|e im Bauen“ (Turning point\|s of building) is the name of an exhibition at the “Pinakothek der Moderne” in Spring 2010. In addition to contributions of the industrialization in the building industry from 1850 to the present day, the exhibition also serves as a platform, to demonstrate new possibilities of computer-aided parametric design and the closely related computer aided manufacturing (CAM). In this context, we took the chance to build a sculpture in Scale 1:1 to show the potential of a constant digital workflow and the digital fabrication. Through the digital chain from design to manufacturing, the efficiency has been increased by the computer and allows the implementation of new complex architectural structures. But the efficiency of the high-degree-automation through the use of computerized machines usually ends in the production of the components. Because this coincidence of the elements in the assembly often proves cost and time, the aim of the project was to optimize both, the production of components and their assembly as well. As part of the wintercourse 2009/2010 different aspects of automation have been reviewed and new solutions have been analyzed. Together with 15 students of the Faculty of Architecture the complete digital chain started with the first design ideas, about parametric programming through production and assembly had been researched, implemented and brought to reality. In the first steps, the students had to learn about the potential, but also about the problems coming with the digital-design and the attached digital-production. There for the course took part at our computerlab. In weekly workshops, all ideas have been implemented and tested directly in the 3-dimensional parametric model. And thanks to the interdisciplinary work with the Department of Structural Design also static factors had been considered, to optimize the form. Parallel to the digital form-finding process, the first prototypes have been produced by the students. By using the chairs 3D-CNC-Mills we were able to check the programmed connection detail in reality and apply the so learned lessons to the further development. After nearly 3 month of research, designing, planning and programming, we were able to produce the over 1000 different parts in only 4 days. By developing a special pre-stressed structure and connection detail it was also possible, to assemble the whole structure (13.5m x 4.5m x 4m) in only one day. The close connection between digital design (CAD) and digital manufacturing (CAM) is an important point of our doctrine. By the fact, that the students operate the machines themselves, but also implement projects on a scale of 1:1, they learn to independently evaluate these new tools and to use them in a meaningful way.

summary	Daylighting is an important part of designing sustainably. Daylighting is the use of natural light for primary interior illumination. This reduces our need for artificial light within the space, thus reducing internal heat gain and energy use. Direct sunlight, once it enters the building, is not only light but heat, and that additional heat will need to be taken into account in your energy analysis." While Autodesk Revit Architecture 2010 (ARA) itself cannot perform the actual analysis, there are some ways to do that. This papper focuses on the study of parametric modeling using a BIM tool for daylighting analysis. This paper presents the first part of the building method of LUME, a plug-in maked whit C# programming language in Microsoft Visual Studio 2010 and ARA Software Developer Kit (SDK) package. The script accepts as its input a standard three dimensional model of building opening and his position on space.

source	SIGraDi 2009 - Proceedings of the 13th Congress of the Iberoamerican Society of Digital Graphics, Sao Paulo, Brazil, November 16-18, 2009
summary	The knowledge of latest technology that allows the development of competitive products in reduced times is crucial to guarantee a sustainable growth of the national industry. This work presents the development of a computational system for the Virtual Design of products, the VirtusCADE, which is a CAD/CAE interactive software (Computer Aided Design/Computer Aided Engineering). The VirtusCADE includes 3D geometric modeling of surfaces and solids and mesh generation. The system uses the parametric modeling of surfaces, including algorithms for determination of intersection between surfaces and for triangular mesh generation in trimmed parametric surfaces. The graphical interface is interactive and allows the direct real time manipulation of objects (lines, surfaces and solids) in 3D using the OpenGL technology. The system prioritizes the usability, implementing several graphic tools that facilitate the manipulation in 3D. The VirtusCADE contemplates the structural simulation through the Finite Element Method. The code architecture is based on oriented object programming, which allows great scaling capability for the implementation of new tools. This project has great applicability in numerical simulation of physical phenomena, such structural analysis of buildings, vehicles parts, with impact in the industries of civil construction, metal-mechanics, aerospatial, naval and automotive.

title	Modelling Behaviour of Configurable VR Applications
source	International Journal of Architectural Computing vol. 7 - no. 1, 77-103
summary	Creation of complex behaviour-rich and meaningful content is one of the main difficulties that currently limit wide use of virtual reality technologies in everyday applications. To enable widespread use of VR applications new methods of content creation must be developed. In this paper, we propose a novel approach to designing behaviour-rich virtual reality applications, called Flex-VR. The approach enables building configurable VR applications, in which content can be easily created and modified by domain experts or even common users without knowledge about VR design and computer programming. The VR content is configured from reusable programmable content elements, called VR-Beans. Appearance and behaviour of the VR-Beans are controlled by scripts programmed in a novel high-level language, called VR-BML (Behaviour Modelling Language). The language enables specification of generic behaviours of objects that can be dynamically composed into virtual scenes. The paper introduces the Flex-VR component and content models, describes the VR-BML language and provides an example of a Flex-VR application in the cultural heritage domain.

summary	In order to support the conceptual design, the architect used throughout the years, mockups - scaled physical models - or perspective drawings that intended to predict architectural ambience before its effective construction. This paper studies the real time interactive visualization, focused on one of most important aspects inside building space: the natural light. Although the majority of physically-based algorithms currently existing was designed for the synthesis of static images which may not take into account how to rebuild the scene - in real time - when the user is doing experiments to change certain properties of design.

summary	In Norway there has been an increased focus on participatory planning the latter years. The public is now supposed to be included in the planning process. The documents which the public have access to usually consists of the project`s technical drawings. In some cases, the documents include perspective drawing or computer rendering supplied by the stakeholder. Most affected parties are non professional in terms of planning, and have little or no experience dealing with the plans. Therefore, the information they rely on most cases is the perspective images, which easily can be manipulated. A system that enables all parties engaged in the planning process to visualize planning scenarios in a much realistic way is therefore needed. Virtual Reality is a tool that enables the viewer to move freely in a three dimensional digital environment. In this virtual world, different levels of interactivity can be added. The Norwegian University of Life Sciences (UMB) has recently installed a new immersive Virtual Reality system based on the idea of ConCave theatre. This research study is making use of the new ConCave theatre in order to test whether VR can be used as an enhancement of the communication process between professionals and amateurs and between professionals. By presenting digital models of different level of detail to two subject groups consisting of students with planning background and two groups without such experience we first investigated perception in an immersive VR-environment.

summary	In his book “Cinema as an Art”, Rudolf Arnheim states that cinema (art) cannot achieve to realize the mechanical reproduction of the real (nature) because of technical limitations but also states that these limitations are compulsory for the production of art. According to Arnheim, these limitations cause artists to interpret the real (nature) and to materialize impressive expressions. Architecture presents its productions to its viewers (customers) using some kind of media, before materializing them in the physical world. The most common ones nowadays are technical drawings (perspectives), models, photographs and computer aided models and animations. The architect makes impressive expressions based on the technical limitations of the medium he/she uses. With the computer technology, simulation gives possibilities to the architect for presenting and experiencing his/her art very close to reality. Simulation is the best way to reproduce the reality mechanically, when it is compared to other mediums. In this study, simulation’s potential as an architectural presentation technique is examined through Arnheim’s vision and Rembrandt’s painting “Staalmeesters”.
