summary	The article underlines the problem of introducing computer techniques into the education process in master degree studies in architecture. Following the consumer society, developing technologies, changing social values architecture education changed its continuous principle into two-level system. The system well known from other fields of education results in diversified level of knowledge between admitted students on master studies. This fact in together with large exercise groups and a relatively short time allocated with the project requires methodical approach in relationship between a student and a teacher. The article focuses on complexity of a design process within different stages. Special attention is placed to an early design phase of shaping an architecture form because it demands different ways of presentation including freehand sketching, physical modelling and digital modelling. These tools correspond to the subsequent three phases of the design process, starting with exploration of the idea and context, functional decisions and determining the aesthetics. In authors opinion, the first phase of teaching process held without the use of computer techniques led to a higher originality of the architecture concept and increased efficiency in design process.

summary	A routine is a fixed program, a sequence of actions regularly followed. And the concept can be adapted at different levels in the understanding of the dynamics of cities. Today's built environments are in fact increasingly characterized by series of iterations daily performed by infrastructures, networks, buildings, and people ? as part of a well-structured pattern of components. In this sense, the city becomes a system that not only creates routine, but also pushes its urban mechanisms, its architectural spaces, and its human interactions towards performance, efficiency and the 'standard.' A-priori and top-down implementations of new technologies emphasize routine-based built environments, leaving almost no room for the (extra)ordinary. But how can the spaces, infrastructures, and places that define the social experience of tangible environments not incorporate elements of inherent spontaneity, informality, and even error that let us break routine patterns?

summary	This paper presents an algorithm for the formation of single or double curved revolved surface’s infrastructures through standardized parts. Any revolved surface can be generated with only two types of parts, interconnected by a ribbed structure technique. The proposed method differs from the accustomed orthogonal rib structures by the varying angle in-between coupling parts. The algorithm can be customized through several parameters like the number, width of parts and thickness of the material used for the infrastructure. The algorithm also offers an advantageous nesting pattern with minimum loss of material regardless of the revolved surface cross-section.

title	Communicative Profiles - Generative Art Applied in Information Access Interfaces
source	International Conference on Generative Art
summary	The path of ubiquitous computing and the domain of ambient intelligence are expected to stimulate emergence of new interaction paradigms. There is a need to develop adequate means of natural communication with an intelligent information system. This, presumably, requires a more integrated development of form and function of the interface. The interface design concept proposed in this paper is based on an evolutionary mechanism and it aims at development of an interactive and adaptive animation system. It is proposed that through a coherent process of adaptation of a system functionality and its appropriate visualization, a personalized and more natural experience of interaction might be achieved.

title	The Side Effect of a Generative Experiment
source	International Conference on Generative Art
summary	This paper discusses the issue expressed in the call for the Generative Art 2002 conference that says: "GA is identifiable as one of the most advanced approaches in creative and design world." In this paper the value of Generative Art for the art, science and design worlds is described in the reference to a generative experiment. The experiment has been conducted in industrial environment with the aim of defining possibilities for natural interaction of humans with machines. In specific, the experiment examined an option for visual adaptation in accordance to user feedback. In the context of the experiment's outcome the issue of recognizability of Generative Art values is discussed. Generative Art can be identified but is not widely recognized as "one of the most advanced approaches in creative and design world". What makes it difficult for designers to switch to generative thinking and accept immediately Generative Art as the possible way of advancing traditional design methods? And what makes it promising to keep searching for ways of application of Generative Art in contemporary design? Some possible answers, proposed in this paper, aim at contributing to the discussion about the changing role of artists and designers in the contemporary society.

source	Digital Design: The Quest for New Paradigms [23nd eCAADe Conference Proceedings / ISBN 0-9541183-3-2] Lisbon (Portugal) 21-24 September 2005, pp. 565-572
summary	This paper is based on the experience with creation of a small knowledge base about the between-war architecture of one of the Warsaw districts. Design, as a process of creation, combines processing of procedural and declarative knowledge. There is a vast amount of declarative knowledge of different kinds to be collected even before the design process starts. Advances in ICT (Information and Communications Technologies), particularly in such field as databases, data warehousing and knowledge engineering, make it a lot easier to design complex systems, which will allow to combine procedural and declarative knowledge. We used historic-architectural knowledge as an example of the second kind mentioned here. The sources of this kind of information are dispersed, the data is gathered in various formats, using different standards and for various purposes. Past experiences with creating detailed architectural heritage inventories in Poland led us to a conclusion that such a subject specific knowledge base may be a part of larger hierarchical structure, which still needs to be built. These are the reasons for adopting a data-warehouse-like structure, which responds with it’s tools to such needs. The assumptions for such system are presented and the context-based structure is discussed. During our work we also came for some more general conclusions. These concern a need for disseminating an OpenSource Society ideas through all the keepers of information related to architectural heritage.

title	A Computer Aided Design Model for Climate Responsive Dwelling Roof
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. 315-332.
summary	Computer-Aided Design models have generated new possibilities in the sustainable design of buildings. Computer models assisting different aspects of architectural design have been developed and used for several decades. A review of contributions of computing to architectural design is given by Gero. Most of the conventional simulation computer programs do not actively support design development and optimization, specially at the formative design stages. It is well established that most decisions that affect comfort and building energy use occur during the formative design stages of the project. Furthermore, the efforts required to implement those decisions at the beginning of the design process are small compared to the effort that would be necessary later on in the design process. Therefore, if sustainable design issues are going to receive an appropriate level of consideration at the beginning of the design process, they must be presented in a way which is useful to the architect and fits with other things the architect is considering at that time. Design is seen as a problem-solving process of searching through a space of design solutions. The process of finding a solution to a design problem involves, identifying one or more objectives, making design decisions based on the objectives, predicting and evaluating the performance to find the acceptable decisions. Each of these activities can be performed inside or outside the formal model. In designing a roof, an architect or building designer has to make many decisions on the materials. The arrangement of these materials determines the aesthetic appearance of the roof and the house. Other considerations that affect the choice of roofing materials are thermal performance, rain, fire protection, cost, availability and maintenance. Recyclability of materials, hazardous materials, life-cycle expectancy, solutions, and design options as they relate to the environment also need to be considered. Consequently, the design of roof has become quite a complex and multifaceted problem. The principal need is for a direct design aid which can generate feasible solutions and tradeoff performance in conflicting requirements and prescribe the optimum solution. This paper presents a conceptual Computer Aided Design model for dwelling roof. It is based on generation and optimization paradigms of Computer Aided Design; which is diametrically opposite to conventional simulation. The design of roof (design goal) can be defined in terms of design objective as "control radiant and conduction heat." This objective must be satisfied to achieve the design goal. The performance variables, such as roof ceiling surface temperature or new thermal performance index (TPI*) must acquire values within certain ranges which will satisfy the objective. Given the required inputs, this computer model automatically generates prescriptive quantitative information to design roof to achieve optimum thermal comfort in warm humid tropics. The model first generates feasible solutions based on the decision rules; next it evaluates the thermal performance of the roof taking into account design variables related to the building‚Äôs roof and finally it applies numerical optimization techniques to automatically determine the optimum design variables, which achieve the best thermal performance. The rational and methodology used to develop the proposed model is outlined and the implementation of model is described with examples for climatic and technological contexts of India and Australia.

title	A method for Constructing a Reference Image Database to Assist with Design Process. Application to the Wooden Architecture Domain
source	International Journal of Architectural Computing vol. 3 - no. 2, 227-244
summary	Designing architectural projects requires the introduction of references, because design is an activity oriented towards a result which does not yet exist. If we summarise the current categories used in Artificial Intelligence to characterise the different forms of reasoning, we are able to consider that design is more the concern of the induction or the abduction mechanism than the deduction mechanism. Moreover, the main characteristic of the designer's activity is to work towards non-routine situations with the use of many references. In this paper we will present method principles to construct a reference image database. These references will enable the designer to further in solving the design problem. To illustrate these reference usage, we choose photographic images belonging to the wooden construction domain We also present at the end of the paper an experiment which aims to evaluate the real help that this reference image database can bring to designers during their creation task.

summary	Traditional Japanese wooden buildings are designed on the basis of a systematised building system. A typical systematised method called "kiwari" sets parametric/algorithmic rules that determine the dimensions and positions of components. These methods, which facilitate traditional wooden architecture, have cultural value. In this work, the authors report a representation method that is aimed at creating a three-dimensional model and a network-based representation of the traditional Japanese wooden building system. A systematised method that enables the construction of a quadruped gate using the traditional Japanese wooden building system is analysed through algorithm creation and visualisation of relations from the variables of the instances by the proposed system.

summary	What is a computer in the hands of an architect? What it can develop into? This paper is an attempt at determining the main limitations and possibilities of the digital-circuit engineering with regard to the creation of three-dimensional forms. All the limitations seem to have a common reason, namely the user's lack of self-awareness. It is user who decides whether the instrument is just a secondary carrier of information about the designed object or whether it serves as a medium for the creation of three-dimensional designs, an environment for the incubation and presentation of the very idea. The reader will find here some remarks on creation in virtual space as a separate phenomenon of creating forms which are no longer restricted by reality. It presents a global computer network on the threshold of the era of three-dimensional virtual space with unlimited creation possibilities.

summary	In this paper computer is considered as the "hypertool" - union of technical and methodological aspects of a tool. CAAD and its space is a microcosmos incompatible with our real world. CAAD performs the role of electronic modeller that redefines space and substance of our model by structure of the CAAD software and reduces the range of possible operations, transformations of a model. The environment that is internally wild opened - everything is an information easy to exchange, but externally is excluded from direct influences and manual access. I try to discover typical and unique features of this virtual environment of CAAD, substance of virtual model and computer as the tool of architectural creation. Medium that redefines" architects" imagination.

source	First International Conference on Critical Digital: What Matters(s)? - 18-19 April 2008, Harvard University Graduate School of Design, Cambridge (USA), pp. 181-194
summary	In resent years, digital design tools have become prevalent in the design community and their capabilities to manipulate geometry have grown into a trend among architects to generate complex forms. Working as computational design consultant in an engineering firm, between architecture and engineering we often come across the problems generated by a superficial use of digital tools in both disciplines and the incapacity of the current system to cope with their byproducts. Here we will discuss the problems we see with the current system and the opportunities opened by digital design tools. Two guiding concepts are simplexity [the desire to fine tune and build a system that yields a solution to a specific design problem by collapsing its inherent complexity] and defamiliarization [a side effect of having to represent things as numbers]. They can both affect the designer as an individual who chooses to engage with digital media as well as the production system in which he/she is embedded since he/she will have to find new channels of communication with other parties. To demonstrate our strategy and the obstacles faced we will examine our involvement in the development of a computational design solution for a small house designed by Future Systems architects.

summary	The increasing trend in architecture to create unconventional forms opened up a new area of investigations in the employment of computational methods in design and construction. Our investigation is undertaken within a structural engineering firm, Adams Kara Taylor and focuses on finding ways to design structural solutions that respect criteria of efficiency, architectural intentions as well as intrinsic properties of the geometry. In this paper, we present various approaches on discretization where a project is presented as a continuous form, envelope or skin that must be subsequently subdivided in order to yield a framing or cladding solution compatible with different manufacturing, design and engineering considerations. The first part of this paper illustrates such a project where we applied and developed one of our discretization approaches. The second part of the paper focuses on generalization where we present a series of methodologies and corresponding software tools developed for the purpose.

summary	The pervasiveness of the digital media has set the ground for tighter collaboration between the discipline involved in the architecture practice and potential for reconfiguring the well-established communication patterns in the industry to occur. Considering the context thereof, Computation Design Consultancy aims to connect different considerations and priorities raised by different parties involved in the architecture production system by means of digital computation. Here, we discusses the inefficiency of the existing system in engaging with the contemporary context influenced by the digital media as well as our approaches and findings thus far though the consultancy work.

title	Ray tracing complex scenes
source	Computer Graphics, 20 4, 269-78
summary	A new algorithm for speeding up ray-object intersection calculations is presented. Objects are bounded by a new type of extent, which can be made to fit convex hulls arbitrarily tightly. The objects are placed into a hierarchy. A new hierarchy traversal algorithm is presented which is efficient in the sense that objects along the ray are queried in ancient order. Furthermore , we demonstrate that it is currently possible to raytrace scenes containing hundreds of thousands of objects.

title	New techniques for ray tracing procedurally defined objects
source	Computer Graphics, 17 3, 91-102
summary	We present new algorithms for efficient ray tracing of three procedurally defined objects: fractal surfaces, prisms, and surfaces of revolution. The fractal surface algorithm performs recursive subdi- vision adaptively. Subsurfaces which cannot intersect a given ray are culled from further consideration. The prism algorithm transforms the three-dimensional ray-surface intersection problem into a two-dimensional ray-curve intersection problem, which is solved by the method of strip trees. The surface- of-revolution algorithm transforms the three-dimensional ray-surface intersection problem into a two-dimensional curve-curve intersection problem, which again is solved by strip trees.

summary	In this paper, we introduce the Nip and Tuck Method, which provides a general approach to construct complicated shapes without using high-level software and/or without solving complex mathematical problems. Our framework is based on discrete version of Gauss-Bonnet theorem, which states that the sum of vertex angle defect in a given piecewise planar manifold or manifold with boundary mesh surface is independent of the number of vertices, faces and edges. Based on this property, architects and designers can simply introduce negative and positive curvatures in the places they want to obtain desired shapes. We presented Nip and Tuck Architecture to freshman students in beginning level design studios to design arches with modular elements along with other methods. Several groups of students, that chose to use Nip and Tuck approach to obtain individual modules, were able to design and construct unusual small-scale arches.

summary	Advances in construction automation have primarily focused on creating heavy machines to accomplish repetitive tasks. While this approach is valuable in an assembly-line context, it does not always translate well for the diverse terrain and dynamic nature of construction sites. As a result, the use of automation in the architectural assembly has lagged far behind other industries. To address the challenges of construction-site assembly, this project suggests an alternative technique that uses a fl eet of smaller robots working in parallel. The proposed method, which is inspired by the construction techniques of insect colonies, has several advantages over the use of larger machines. It allows for much greater on-site fl exibility and portability. It is also easy to scale the operation, by adding or removing additional units as needed. The use of multiple small robots provides operational redundancy that can adapt to the loss of any particular machine. These advantages make the technology particularly suitable for construction in hazardous or inaccessible areas. The use of assembly robots also opens new horizons for design creativity, allowing architects to explore new ideas that would be unwieldy and expensive to construct using traditional techniques. In our tests, we used a team of small mobile robots to fold 2D laser-cut stock into 3D curved structures, and then assemble these units into larger interlocked forms.
