summary	Korean traditional structure is constructed as prefabrication jointed in largely characterized by its unique components under the specific rules of assembly and proportion. This point is a double-edges sword. Because, while various shapes and sizes of components based upon an objected-oriented form appear the potential possibility of producing changeable prototypes to build up, these various characters of components and several jointed methods has made difficulties to handle. Accordingly, an automatic 3D modeling algorithm is focused on the methodology of changeable prototypes of Korean Traditional architecture keeping traditional jointed methods with setting various characters of components

summary	In this paper, we present a user-friendly and practical method for seamless integration of computergeneratedimages (CG) with real photographs and video. In general, such seamless integration isextremely difficult and requires recovery of real-world information to simulate the same environment forboth CG and real objects. This real-world information includes camera positions and parameters,shapes, material properties, and motion of real objects. Among these, one of the most important islighting.Image-based lighting that is developed to recover illumination information of the real world fromphotographs has recently become popular in computer graphics. In this paper we present a practicalimage-based lighting method that is based on a simple and easily constructable device: a square platewith a cylindrical stick. We have developed a user-guided system to approximately recover illuminationinformation (i.e. orientations, colors, and intensities of light sources) from a photograph of this device.Our approach also helps to recover surface colors of real objects based on reconstructed lightinginformation.

summary	Estimating a building's performance is part of the engineering and architecture discipline. Nowadays, this estimation is done using analysis tools. In many cases, these analysis tools require specialized building models that are simplifications of the actual models. Unfortunately, the adaptations that need to be done to an existing model are tiresome and make the architect less willing to evaluate variations of the building design. Moreover, in the case of buildings with complex shapes, the analyses tend to be less reliable. These problems also occur when algorithmic approaches are used to generate the building design, as the algorithmic script needs to be adapted to satisfy the requirements of the analysis tool, or the manual adaptation of the generated model needs to be repeated each time the script is executed. To solve these issues we propose Algorithmic-Based Analysis. This is a Generative Design method that, utilizing a single algorithmic-based representation of a building, can generate not only the traditional CAD or BIM model, but also specialized models for use in different kinds of analysis.

source	SIGraDi 2012 [Proceedings of the 16th Iberoamerican Congress of Digital Graphics] Brasil - Fortaleza 13-16 November 2012, pp. 491-494
summary	This article aims to promote the discussion about how the adoption of Building Information Modeling systems in management processes and three-dimensional geometric modeling can interfere in the design process and construction of complex shapes in architecture. To that end, we assembled a theoretical-practical referential about the use of non-Euclidean forms in contemporary architecture and BIM tools, illustrated with iconic design processes developed by Frank Gehry and Zaha Hadid. Finally, there was the importance of BIM tools to a new understanding of architecture, by enabling the construction of complex shapes.

title	Digital Manufacturing within Design Jewelry Production: A Study on the Formation and Appropriation of Technologies
source	Gomez, P and Braida, F (eds.), Designing Possibilities - Proceedings of the XXV International Conference of the Ibero-American Society of Digital Graphics (SIGraDi 2021), Online, 8 - 12 November 2021, pp. 535–545
summary	Digital fabrication technologies have been developing rapidly; the number of shapes that can be created in different design sectors by this technology has grown exponentially and in the jewelry field it’s not different. Jewelry is an old and constantly evolving craft and the digital manufacturing was first incorporated into it as a form of prototyping and problem solving, but today there are many creative uses for it. This article presents data on some productive practices, prioritizing information on learning, knowledge domain and access to digital fabrication technologies. We discuss the ways which the technology is appropriated in a specific socio-productive context of design jewelry production located in Northeastern Brazil. The study identifies the techniques and technologies effectively appropriated by the surveyed audience and discusses the conditions of these appropriations.

title	Some Phenomena of seeing shapes in design
source	Design Studies, v 16, n 3, pp. 367-385
summary	This paper is a look at some of the pyschological results that suggest how shape emergence manifest itself in the human mind. The first interesting result goes back to top down expectation guiding recognition. Some experimental suggest that it is easier (quicker) to recognize shapes which we have some alternate mental familiarity. (I.E. verbal, structural descriptions). So if we can easily say a shape then we can easily discern it as an emergent shape. The paper then goes on to discuss the definition of emergent subshapes and gives various authors definitions of what makes up and emergent shape. One interesting classification is the difference between explicit and implicit emergent shapes made by Mitchell. This difference amounts to a fine line between imagination and emergence. The results of an experiment between experienced and in-experienced designers is discussed. The results suggest that experienced designers are able to find more emergent shape than non experienced designers. From these results and from the opinions of others, the author goes on to specify 3 phenomena related to emergent recognition. The first is as above that it is easier to see shapes with which we are familiar. Second from this, the harder shapes are found after the initial period. Third, from the first two, time is required to find more subshapes. The author then searches for an explanation of this phenomena. He suggests that the underlying cause is related to an experience person having a lower threshold of what it is to be a member of a shape. When seeing an L shape the experienced design is likely to consider it also a square, because his requirement for the set of features which must be present for some object to be a considered a square is a smaller set than the inexperienced. While the author suggests that this is a phenomena it is actually an hypothesis. An alternate hypothesis may be that top down inhibitions effect the bottom up performance of the inexperienced design more because of different representation.

summary	This study presents a novel, sustainable method for producing diverse concrete tiles with a reusable mould, addressing the waste issue associated with traditional tile moulds. Our digital manufacturing system, composed of a Rhino Grasshopper-based design system and an electric actuator-based kinetic mechanism, simplifies the construction process and lowers costs. The effectiveness of this method is showcased through six case studies, demonstrating its adaptability in diverse morphing tile designs, including the reinterpretation of traditional Islamic pattern. This approach opens new possibilities for the cost-effective, sustainable, and versatile use of concrete tiles in architecture.

source	CAAD Futures ‘93 [Conference Proceedings / ISBN 0-444-89922-7] (Pittsburgh / USA), 1993, pp. 19-36
summary	In human design processes, many drawings of shapes remain incomplete or are executed inaccurately. Cognitively, a designer is able to discern these anomalous shapes, whereas current CAAD systems fail to recognize them properly so that CAAD systems are unable to match left-hand-side conditions of shape rules. More unfortunately, as a result, current CAAD systems fail to retrieve right-hand-side actions. In this paper, multi-layered neural networks are constructed to solve the recognition and transformation of ill-processed shapes in the light of recent advances of connectionism in cognitive psychology and artificial intelligence.

title	From digital design to physical model - Origami techniques applied to dynamic paneling shapes for acoustic performance control

summary	The recent trend toward non-standard and free form architecture has generated a lot of debate among the Scientific Community. The reasons can be found in the renewed interest in organic shapes, in addition to recent and powerful capabilities of parametric platforms. In this regard, the Visual Programming Language (VPL) interface gives a high level of freedom and control for conceiving complex shapes. The geometric problems in identifying a suitable shape have been addressed by relying on the study of Origami. The control of variable geometry has required the use of algorithmic models that ensure fast changes and free control of the model, besides a physical one made of rigid cardboard to simulate its rigid-foldability. The aim is to present a prototype of an adaptive structure, with an acoustic application, to control sound quality and perception in spaces where this has a central role, such as theatres or concert halls.

summary	Public open spaces (parks, squares and other gathering places) can only be grasped from a simultaneous view of their attributes. In an ongoing Phd research project we propose to overcome the limitations of traditional-descriptive urban morphology methods in dealing with this simultaneity derived from their many shapes, functions, uses and relations within the urban structure. After developing the relations between formal attributes and intangible spatial properties, their identity and proximity may be disclosed by multivariate statistical analysis and data mining techniques. We outline a multidimensional method for the synchronic analysis and classification of the public open spaces departing from a research corpus of 126 Portuguese urban squares, whose analysis is intended to interactively (re)define it. The work done so far is presented, which comprises: (i) firming the concepts, criteria and attributes to extract; (ii) survey on theories, methods and spatial analysis tools and shortcomings identification; (iii) adaptation and/or creation of new methods and tools; (iv) creation of databases from CAD and GIS environments; (v) research on multivariate analysis, data mining and data visualization techniques.

summary	It is a great challenge to digitally generate emotionally satisfying patterns with national style characteristics to meet diversified consumer demands for national patterns. As the core of national culture’s gestation, growth and development, cultural genes can realize cultural inheritance and maintain national identity . From the view of design, the basic feature elements of cultural genes are extracted by original national pattern deconstruction and semantically summarized to form specific cultural design genes suitable for the rapid design of national pattern. Further, the topology principle and ComputerAided design is introduced to simultaneously generate pattern shapes using Self-Crossing and Cross-Crossing transformation by shape grammar. Then, the pattern elements are arranged according to the initial ethnic pattern composition rules to generate new series of ethnic patterns. Finally, Chinese Tibetan pattern is patterned as an example to demonstrate that this research can creates patterns faster and in line with the user's intent.

title	Parametric environment for internalization and classification of models generated by the Shap-E tool
source	García Amen, F, Goni Fitipaldo, A L and Armagno Gentile, Á (eds.), Accelerated Landscapes - Proceedings of the XXVII International Conference of the Ibero-American Society of Digital Graphics (SIGraDi 2023), Punta del Este, Maldonado, Uruguay, 29 November - 1 December 2023, pp. 1689–1698
summary	Computing has been increasingly employed in design environments, primarily to perform calculations and logical decisions faster than humans could, enabling tasks that would be impossible or too time-consuming to execute manually. Various studies highlight the use of digital tools and technologies in diverse methods, such as parametric modeling and evolutionary algorithms, for exploring and optimizing alternatives in architecture, design, and engineering (Martino, 2015; Fagundes, 2019). Currently, there is a growing emergence of intelligent models that increasingly integrate computers into the design process. Demonstrating great potential for initial ideation, artificial intelligence (AI) models like Shap-E (Nichol et al., 2023) by OpenAI stand out. Although this model falls short of state-of-the-art sample quality, it is among the most efficient orders of magnitude for generating three-dimensional models through AI interfaces, offering practical balance for certain use cases. Thus, aiming to explore this gap, the presented study proposes an innovative design agency framework by employing Shap-E connected with parametric modeling in the design process. The generation tool has shown promising results; through generations of synthetic views conditioned by text captions, its final output is a mesh. However, due to the lack of topological information in models generated by Shap-E, we propose to fill this gap by transferring data to a parametric three-dimensional surface modeling environment. Consequently, this interaction's use aims to enable the transformation of the mesh into quantifiable surfaces, subject to collection and optimization of dimensional data of objects. Moreover, this work seeks to enable the creation of artificial databases through formal categorization of parameterized outputs using the K-means algorithm. For this purpose, the study methodologically orients itself in a four-step exploratory experimental process: (1) creation of models generated by Shap-E in a pressing manner; (2) use of parametric modeling to internalize models into the Grasshopper environment; (3) generation of optimized alternatives using the evolutionary algorithm (Biomorpher); (4) and classification of models using the K-means algorithm. Thus, the presented study proposes, through an environment of internalization and classification of models generated by the Shap-E tool, to contribute to the construction of a new design agency methodology in the decision-making process of design. So far, this research has resulted in the generation and classification of a diverse set of three-dimensional shapes. These shapes are grouped for potential applications in machine learning, in addition to providing insights for the refinement and detailed exploration of forms.

title	Optimizing Solar Insolation in Transformable Fabric Architecture: A parametric search design process
doi	https://doi.org/10.52842/conf.ecaade.2010.461
source	FUTURE CITIES [28th eCAADe Conference Proceedings / ISBN 978-0-9541183-9-6] ETH Zurich (Switzerland) 15-18 September 2010, pp.461-470
summary	A design studio and a parallel research project focused on transformable fabric architecture. To facilitate a part of this work, computer based shape generation tools were used to optimize the placement of thin-film photovoltaic cells onto a transformable roof structure. In addition, the tension membrane fabric is rigged in a way that is similar to a sailing boat. The fabric is set into position by winches and cables. The winches are hand-operated so as to lower the overall energy cost. The initial computer models proceeded concurrently with the mockup of small-scale physical prototypes. In addition, the author used an open source programming language to implement a particle spring real time simulation of the fabric shapes. The simulation included a three-dimensional graphical representation of solar insolation and helped to further determine the physical geometry of the project. One of the goals was to evaluate whether larger transformations to the structure as a whole or smaller movements in the fabric would help to optimize the solar insolation benefits. As the examination of potential forms narrowed down to classical saddle shapes, the practical details of rigging the fabric imposed further limitations on its transformable nature. This paper is focused on how modeling with ad hoc tools and especially real-time computer simulation influenced the direction of the work.

summary	Paradigmatic components take the form of a sensitive mesh that reacts to all things experienced. The symbolic universe expresses techno-scientific progress through a linguistic renovation of art. Art not only expresses but also gestates the world. Today, in order for art to generate and give birth to shapes, words and images that match the modern notion of the time factor, in order for art to be able to take part in the generation of new knowledge by means of a new, specific language and say the things that want to be said, art needs digital language. Although at an initial stage, digital art has the privilege of participating in the genesis of profound changes in the current paradigm. This process is ratified in .El milagro secreto. by Borges and .The reflecting Pool. by Viola.

summary	Parametric design and digital fabrication are becoming ubiquitous tools to contemporary architecture and imply a different design process. With this new perception of the contemporary production we have designed a façade sun shade using fractal geometry as a generative system. Fractals are complex shapes generated with simple rules, so it is relatively easy to change the final geometry when we work with parameters. The design process made possible the creation of different options for the brise-soleil using parametric definitions. Some solutions were physically modeled using rapid prototyping, which we consider an essential tool in the contemporary design process. The whole process conducted to the conclusion that architects need to incorporate a new set of skills when working with digital fabrication.

title	Controlling Chaos: a Simple Deterministic System for Creating Complex Organic Shapes
source	International Conference on Generative Art
summary	It is difficult and frustrating to create complex organic shapes using the current set of computer graphic programs. One reason is because the geometry of nature is different from that of our tools. Its self-similarity and fine detail are derived from growth processes that are very different from the working process imposed by drawing programs. This mismatch makesit difficult to create natural looking artifacts. Drawing programs provide a palette of shapes that may be manipulated in a variety ways, but the palette is limited and based on a cold Euclidean geometry. Clouds, rivers, and rocks are not lines or circles. Paint programs provide interesting filters and effects, but require great skill and effort. Always, the details must be arduously managed by the artist. This limits the artist's expressive power. Fractals have stunning visual richness, but the artist's techniques are limited to those of choosing colours and searching the fractal space. Genetic algorithms provide a powerful means for exploring a space of variations, but the artist's skill is limited by the very difficult ability to arrive at the correct fitness function. It is hard to get the picture you wanted. Ideally, the artist should have macroscopic control over the creation while leaving the computer to manage the microscopic details. For the result to feel organic, the details should be rich, consistent and varied, cohesive but not repetitious. For the results to be reproducible, the system should be deterministic. For it to be expressive there should be a cause-effect relationship between the actions in the program and change in the resulting picture. Finally, it would be interesting if the way we drew was more closely related to the way things grew. We present a simple drawing program which provides this mixture of macroscopic control with free microscopic detail. Through use of an accretion growth model, the artist controls large scale structure while varied details emerge naturally from senstive dependence in the system. Its algorithms are simple and deterministic, so its results are predictable and reproducible. The overall resulting structure can be anticipated, but it can also surprise. Despite its simplicity, it has been used to generate a surprisingly rich assortment of complex organic looking pictures.

title	Sistema interativo para análise das relações de afinidade entre o círculo e a elipse [Interactive system for analysis of the circle and ellipse affinity relations]
source	SIGraDi 2002 - [Proceedings of the 6th Iberoamerican Congress of Digital Graphics] Caracas (Venezuela) 27-29 november 2002, pp. 258-260
summary	This paper will try to establish a dialogue between the process of rational geometric construction and the intuitive process of discovering shapes. This will involve: a geometric principle that works as a geometric generation law and two interactive macros. The geometric principle is the affinity between circles and ellipses. The macros, developed in VisualLisp languagefor AutoCAD, allow the students to construct 3D abstract structures. In order to provide support for the student in the task of analysing the 3D structures a methodology has been established to classify shapes giving each one an alphanumeric string. The string reflects the transformation order during the creation of each spacial structure. With the aid of interactivity it is intended that this exercise in discovering space creates a tension allowing the rational and intuitive states of mind overlap.

title	The Idea of Rome: The Shape of Utopy
source	International Conference on Generative Art
summary	After having spent many years in researching about the topographical connections in the city and over the monumental sites and the main architectures of Rome (Palatino, Coliseum, Appia Antica are the areas where he’s working as director of restoring for the Rome Soprintendenza Archeologica) the architect Piero Meogrossi confirms his personal thesis dealing with a strategic oriented direction showing a geomanthic dynamism able to drive the urban growth. A key measure axis used to plan the topography submits the urban shape and the design itself at different ages revealing a virtual matrix whose hidden identity remains astronomically and simbolically characterized by the specific season position of the sun accorded to the dies natalis of Rome, the famous april XXIth connected with the romulean age and the tradictional Squared Rome. Such recognition over the archeological city connects the legendary and historical tales to the main monuments of Rome whose architectonical centers become instrumental knots to control, to accord and to submit to a DNA topographical codex, a symbolical axis-decuimanus by which the romans drive rules of the earth and of the sky (natural perspectives and sundial measures). The utopian reconstruction of the "sun-city plan" has confirmed the quality of the project by Sixtus Vth, the XVIIth century pope who wanted to create, as a new Romulus, a town design able to make comparison with the dynamic shape of the roman antiquities, a "net-city" whose infrastructures (obelisques and streets, etc.) let understood the value of that ancient topographical axis linking each others the center of the optagonal labyrinth to the center of Palatino,to the center of arch of Costantine to the center of Coliseum, to the center of optagonal hall in the golden kingdome by Nero........and further on. Rome, as example of historical town due to the western culture globality, needs to discover and organise those phisical memories,hidden identies whose ancient shape which can yet offer opportunies for the future plans and projects but only if the reality will be pushed by an Utopian vision as the Roman Column 200mt.high,accorded to the shapes upwritten, a Meogrossi’s project winner of the Utopia award in a national competition for the Rome of third millennium.

title	Shape deposition manufacturing
source	Vienna University of Technology
summary	This thesis addresses the issue of rapidly and automatically fabricating functional metal parts directly from CAD models. A newly developed process called Shape Deposition Manufacturing (SDM) is introduced. The process is based on the concept of layered manufacturing in SFF, but uses separate deposition and shaping steps to create a layer. Three dimensionally shaped layers are created using 5-axis CNC machining, to achieve the required geometric accuracy for fully functional shapes. Thermal deposition technologies (thermal spraying, welding) are used to achieve the required material properties. A novel, droplet based deposition process, microcasting, has been developed, to create well- bonded, high-strength material, while minimising the heat input into previously shaped layers. To create layers with a true three dimensional geometry, more detailed building strategies, than used by conventional SFF processes, are required by the SDM process. A CAD based planning system, which addresses these issues by decomposing a solid model of a part into layers and manufacturable, fully three dimensional segments is described. An automated testbed facility installed at Carnegie Mellon's Shape Deposition Laboratory is discussed, and shows the feasibility of automating the process. The microcasting process is explained in detail and its performance in the SDM environment is evaluated. Different strategies and material combinations for the support structure have been developed and are presented with detailed descriptions of several building strategies for parts with various complexity and material quality. Material properties of structures created by the SDM process are evaluated. Problems affecting the accuracy and material integrity of SDM created structures, which mainly involve the buildup of thermal stresses during material deposition, are identified and opened for future research. Finally, various parts, with different complexity, have been built with the SDM process, to show the feasibility and performance of the process. Building time and material usage are evaluated and compared to conventional SFF processes

summary	In a traffic network, capacities of parts of the network restrict the amount of transport that can be handled by this network. The capacity of a given traffic network element is not fixed, but influenced by parameters such as number of lanes, maximum speed, weather, view horizon, and so on. These parameters also define the maximum capacity of complicated intersections. Special shapes of intersections, particularly in urban regions, may further increase or decrease their capacity. This paper investigates an evolutionary algorithm to automatically improve the geometrical layout of parts of an urban network according to externally specified criteria. The paper consists of two main parts. In the first part, a simulation model is described which is able to produce realistically behaving vehicles only by using information about the curb side locations of the roads. This avoids the need to use lane connectivity, signal plans, etc. - which are details that would change during a change of the intersection layout. In the second part of the paper, the simulation changes the road and intersection layouts based on the behaviour of the vehicles. Using a feedback loop allows one to optimize the capacity of the modelled road system while its spatial extents are minimized. As a case study, a special roundabout is examined: 'Central' in downtown Zurich, Switzerland. The particularity of this roundabout is that it partially behaves like a roundabout but also contains two uncontrolled intersections. Due to its central position in the city, the roundabout is very busy with both individual cars and public transport vehicles.
