title	Top-down Approach for Interaction of Knowledge-Based Parametric Objects and Preliminary Massing Studies for Decision Making in Early Design Stages
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. 149-164.
summary	Design activities vary from high-degree of freedom in early concept design stages to highly constrained solution spaces in late ones. Such late developments entail large amount of expertise from technical domains. Multiple parallel models handle different aspects of a project, from geometric master models to specific building components. This variety of models must keep consistency with the design intent while they are dealing with specific domains of knowledge such as architectural design, structure, HVAC, MEP, or plumbing systems. Most of the expertise embedded within the above domains can be translated into parametric objects by capturing design and engineering knowledge through parameters, constraints, or conditionals. The aim of this research is capturing such expertise into knowledge-based parametric objects (KPO) for re-usability along the design process. The proposed case study ‚Äì provided by SOM New York‚ is the interaction between a massing study of a high-rise and its building service core, which at the same time handles elevators, restrooms, emergency stairs, and space for technical systems. This project is focused on capturing design expertise, involved in the definition of a building service core, from a high-rise senior designer, and re-using this object for interaction in real-time with a preliminary massing study model of a building, which will drive the adaption process of the service core. This interaction attempts to provide an integrated design environment for feedback from technical domains to early design stages for decision-making, and generate a well-defined first building draft. The challenges addressed to drive the instantiation of the service core according to the shifting characteristics of the high-rise are automatic instantiation and adaptation of objects based on decision rules, and updating in real-time shared parameters and information derived from the high-rise massing study. The interaction between both models facilitates the process from the designer‚Äôs perspective of reusing previous design solutions in new projects. The massing study model is the component that handles information from the perspective of the outer shape design intent. Variations at this massing study model level drive the behavior of the service core model, which must adapt its configuration to the shifting geometry of the building during design exploration in early concept design stages. These variations depend on a list of inputs derived from multiple sources such as variable lot sizes, building type, variable square footage of the building, considerations about modularity, number of stories, floor-to-floor height, total building height, or total building square footage. The shifting combination of this set of parameters determines the final aspect of the building and, consequently, the final configuration of the service core. The service core is the second component involved in the automatic generation of a building draft. In the context of BIM, it is an assembly of objects, which contains other objects representing elevators, restrooms, emergency stairs, and space for several technical systems. This assembly is driven by different layouts depending on the building type, a drop-off sequence, which is the process of continuous reduction of elevators along the building, and how this reduction affects the re-arrangement of the service core layout. Results from this research involves a methodology for capturing design knowledge, a methodology for defining the architecture of smart parametric objects, and a method for real-time-feedback for decision making in early design stages. The project also wants to demonstrate the feasibility of continuous growth on top of existing parametric objects allowing the creation of libraries of smart re-usable objects for automation in design.

title	Navigating Complex Models in Collaborative Work for (Sustainably) Integrated Design
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. 619-636.
summary	Increasingly intensive use of computational techniques such as parametric-associative modeling, algorithmic design, performance simulations and generative design in architecture, engineering and construction are leading to increasingly large and complex 3D building models which in turn require increasingly powerful techniques in order to be manipulated and interpreted effectively. Further complexities are of course due also to the multi-disciplinary nature of building projects, in which there can be significant variation and even conflict among the aims of architects, engineers and builders, as well as owners, occupants and other stakeholders in the process. Effective use of model information depends to a large extent on sense-making, which can in some ways be helped but also hindered by schemes for organizing the information contained. Common techniques such as layering, labeling (aka ‚Äòtagging‚Äô) and assignment of various other attributes to model objects have significant limitations ‚Äì especially those arising from general problems of language, ontology and standardization, as well as but distinct from issues of interoperability ‚Äì both with respect to locating the desired items in a 3D building model and also with respect to displaying the objects in informative ways which effectively assist collaborative design and decision-making. Sustainable design in particular is an area generally requiring a high level of inter-disciplinary collaboration to achieve highly integrated designs which make multiple use of the elements and systems incorporated (though integrated design may also be pursued without explicit aims of sustainability). The proposed paper describes ongoing research concerning alternatives to the currently common techniques for locating and displaying information in 3D building models in support of sense-making to promote collaborative and integrated design. These alternatives comprise on the one hand interactive geometric-content-based methods for search and classification of model objects ‚Äì as an alternative or complement to common assigned-attribute-based methods ‚Äì and on the other hand visual analytic techniques ‚Äì in contrast to existing, relatively static tabular and "physical" views ‚Äì which can help to increase the informativeness of the geometric data within the model, as well as the non-geometric data that is attached to geometric objects (e.g. as in the cases of BIM and various types of CAE performance simulations). Tests undertaken with architects and engineers in practice and academia to evaluate the proposed methods are also described. Finally conclusions are drawn regarding these methods‚Äô positive present performance and some of their shortcomings, as well as indicating directions for future research concerning the methods‚Äô refinement and extension to help 3D building models become more effective components of the design process than they are at present, both with respect to these models‚Äô present levels of complexity and especially with respect to their anticipated increasing complexity in future.

title	Raciocínio Analógico Paramétrico: uma experiência criativa em arquitetura [Analogical Parametric Reasoning: a creative experience in architecture]
source	SIGraDi 2011 [Proceedings of the 15th Iberoamerican Congress of Digital Graphics] Argentina - Santa Fe 16-18 November 2011, pp. 39-42
summary	The aim of this paper is to examine the role of the analogies in the parametric modeling, particularly as factor of induction of creativity in architecture design process. For this purpose two experiments are presented. In the first one the students tested the relationship involving parametric modeling in the Paracloud and Rhino, that resulted in physical models produced by laser cutter. In the second experiment the students produced algorithms in the Grasshopper, resulting in families of structures. The results allow us to affirm that the parametric modeling stimulates the creativity, therefore allow combining parameters that result in unexpected discoveries.

title	Heavy Design
source	International Journal of Architectural Computing vol. 9 - no. 3, 251-258
summary	Digital tools in architecture have a powerful capability that we have only begun to explore; the questions to ask of them are perhaps not what they can do but what should we use them for? To date, much of the work done in the area of computational design has been used as elaborate patterning - some have called it ‘ornament’. The significance of this ornament is not only pleasure but in its use of digital patterns to represent our current complex and digital age.This representation in itself is not problematic; however, what is problematic is the lack of other meaningful uses of the digital form-generating tools and their distance from a culture of making. The main failing of our use of digital design (algorithmic or not) in architecture to this point is its inability to translate smoothly from the digital world to the physical world. The main reasons for this difficulty in translation are gravity and inherent material properties. Working with gravity and its physical implications is generally considered the role of the structural engineer; as such, engineers have generally created digital tools in this area.The engineer's methodology analyses a structure based on complex structural analysis programming but in order to do this, a detailed description of the structure must already exist. This is not useful in preliminary stages of design. However, the generation of architecture within an environment, which already includes structural principles, may bring us one step closer to this transition of virtual to physical by including gravity in architectural generation while not diminishing the creative form-generating process. An approach has been proposed which responds with a concept of ‘heavy design’. This type of approach incorporates logics from other disciplines, primarily structural engineering, to inform design. The design process incorporates the structural behavior of a system into the architectural model. Engineering offers a mathematical interpretation of the physical world and this is inherently suited to algorithmic design because it is already in equation form. It can thus be programmed into the architectural form generational software. The variables used in the equations become the variables within the architectural design and this inherently brings the natural physical laws to the architecture through a numerical, algorithmic method. The design produced is not a singular answer but rather a responsive vocabulary of a structural system, which is then employed in design in differing conditions. The architecture produced is both function and ornament, having cultural interpretation but carrying out many engineering tasks: a true parametric architecture.

title	Cultura aumentada ou substituída? Distinções entre o arquiteto-ferramenta e o arquiteto-aparelho eletrônico [Culture augmented or substituted? Distinctions between the tool-architect and the robot-architect]
source	SIGraDi 2011 [Proceedings of the 15th Iberoamerican Congress of Digital Graphics] Argentina - Santa Fe 16-18 November 2011, pp. 52-55
summary	This article investigates the notion of an augmented architectural design culture elapsed of the digital revolution. Based on analytical categories proposed by the philosopher VilémFlusser it compares two systems of creative production (the tool-architect and the robot-architect), establishing new perspectives on the architectural design supported by computers. Thereafter, it identifies in the digital design agenda the overvaluation of the generative techniques over the psycho-physiological capacity of man. Lastly, the article discusses Flusser's theories to present the risks and limitations of a design practice determined by the digital techniques.

title	Behavior-based Computational Design Methodologies: Integrative processes for force defined material structures
source	ACADIA 11: Integration through Computation [Proceedings of the 31st Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA)] [ISBN 978-1-6136-4595-6] Banff (Alberta) 13-16 October, 2011, pp. 82-89

summary	With the introduction of physics-based algorithms and modeling environments, design processes have been shifting from the representation of materiality to the simulation of approximate material descriptions. Such computational processes are based upon enacting physical and material behavior, such as gravity, drag, tension, bending, and inflation, within a generative modeling environment. What is often lacking from this strategy is an overall understanding of computational design; that information of increasing value and precision is generated through the development and iterative execution of specific principles and integrative mechanisms. The value of a physics-based modeling method as an information engine is often overlooked, though, as they are primarily utilized for developing representational diagrams or static geometry – inevitably translated to function outside of the physical bounds and parameters defined with the modeling process. The definition of computational design provides a link between process and a larger approach towards architecture – an integrative behavior-based process which develops dynamic specific architectural systems interrelated in their material, spatial, and environmental nature. This paper, focusing on material integration, describes the relation of a computational design approach and the technical framework for a behavior-based integrative process. The application is in the development of complex tension-active architectural systems. The material behavior of tensile meshes and surfaces is integrated and algorithmically calibrated to allow for complex geometries to be materialized as physical systems. Ultimately, this research proposes a computational structure by which material and other sorts of spatial or structural behaviors can be activated within a generative design environment.

title	InfoMatters, a multi-agent systems approach for generating performative architectural formations
source	International Journal of Architectural Computing vol. 9 - no. 3, 205-222
summary	The research paper exemplifies upon a computationally intensive inter-disciplinary research driven design investigation into spatializing the relationship between digital information and physical matter. Focusing on the development of architectural scale urban inserts, the design-research work operates on the intersection of information technology, environmental design, architecture, and computer aided manufacturing domains.The research framework revolves around developing a seamless integration of the aforementioned disciplines in order to establish iterative simulation driven methodologies for generating bottom-up sustainable architectural formations. This is achieved by establishing parametrically driven relational linkages between differential data sets (environmental, social, topological, material etc), which formulate the context (both global and local) within which the proposed project has to be designed. A selforganizing multi-agent system based simulation methodology for generating resultant spatial formations, in time, based on the impacts of the parametric relationships between the aforementioned data sets is eventually embarked upon. This implies, understanding the site as a dynamic information field within which interdependent ecology of agents (representing typology of people, program, structure, speed, desired social interaction etc) with multi-level relational affinities amongst each other as well as the dynamic urban information field. The resultant self-organized multi-agent formations are iteratively mined for identifying logical three-dimensional structural patterns or subjected to programmatic and environmental need driven additional layer of structural simulation with pre-embedded material restraints. An optimized system of multi-performative components that not only populates but also serves as an integrated structural + skin system of the results obtained from the agent based simulations (based upon the degree of inclusion/exclusion of parameters such as the amount of light, sound, wind etc) is subsequently generated. These experimental projects attained the status of self-evolving ecologies of multi-dimensional agents with embodied behavioural profiles, thus providing engaged, highly interdependent design by simulation outputs. The outputs showcase a dynamic system's driven approach towards sustainable design by stressing upon the idea of cohesively binding information and material systems from the very beginning of the design process. Such approaches help in reducing post-optimization of built form and consequently allow for rational understanding of performance criteria and its impact on formal articulations throughout the design process.

title	Using 3D Design Software, BIM and Game Engines for Architectural Historical Reconstruction
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. 493-509.
summary	The use of digital tools has become a tremendous aid in the creation of digital, historical reconstructions of architectural projects. Regular visualization techniques have been used for quite some time and they still pose interesting approaches, such as following cinematic techniques [1]. While common visualizations focus on pre-rendered graphics, it is possible to apply Game Engines [2] for real-time architectural visualization, as witnessed by [3] and [4]. In the course of our teaching and research efforts, we have collected experience with several visualization and modeling techniques, including the use of gaming engines. While the modeling of qualitative geometry for use in regular visualization already poses an elaborate effort, the preparation of models for different uses is often not trivial. Most modeling systems only support the creation of models for a single amount of detail, whereas an optimized model for a real-time system will have fairly different constraints when compared to non-real-time models for photorealistic rendering and animation. The use of parametric methods is one usable approach to tackle this complexity, as illustrated in [4]. One of the major advantages of using parametric approaches lies precisely in the possibility of using a single model to generate different geometry with control over the amount of detail. We explicitly tackle this in a Building Information Modeling (BIM) context, as to support much more than purely 3D geometry and visualization purposes. An integrated approach allows the same model to be used for technical drawings in 2D and an optimized 3D model in varying levels of detail for different visualization purposes. However, while most Building Information Modeling applications are targeted to current architectural practice, they seldom provide sufficient content for the recreation of historical models. This thus requires an extensive library of parametric, custom objects to be used and re-used for historically accurate models, which can serve multiple purposes. Finally, the approach towards the historical resources also poses interpretation problems, which we tackled using a reasonably straightforward set up of an information database, collecting facts and accuracies. This helps in the visualization of color-coded 3D models, depicting the accuracy of the model, which is a valuable graphical approach to discuss and communicate information about the historical study in an appealing format. This article will present the results of different reconstruction case studies, using a variety of design applications and discuss the inherent complexity and limitations in the process of translating an active, evolving model into an environment suitable for use in a real-time system. Especially workflow issues are identified, as the translation of the model into the game engine should be repeated several times, when the model is further refined and adapted. This used to involve a large amount of repetitive work, but the current crop of game engines have much better approaches to manage the updating of the geometry.

summary	Robots are gaining popularity in architecture. Snøhetta has recently purchased their own industrial robot, becoming one of the first architectural offices to adopt robot technology. As more and more architects are exposed to robotic fabrication, the need for easy interoperability, integration into architectural design tools and general accessibility will increase. Architects are discovering that industrial robots are much more than kinematic machines for stacking bricks, welding or milling - they are highly multifunctional and can be used for a huge variety of tasks. However, industry standard software does not provide easy solutions for allowing direct robot control right from CAAD (Computer Aided Architectural Design) systems. In this paper we will discuss existing methods of programming industrial robots, published architectural results (Gramazio and Kohler 2008) and the design of a new user interface that allows intuitive control of parametric designs and customized robotic mass production, by integrating CAM (Computer Aided Manufacturing) functions into CAAD.

title	Tropism-oriented generative design: Analogical models for heterogeneous goal integration
source	Master of Philosophy (MPhil) Thesis. Faculty of Architecture, Building and Planning, The University of Melbourne.
summary	Architecture often requires integration between heterogeneous objectives. Both empirical requirements and speculative aspirations inform design in ways that resist ready formalization under computerizable logic. This thesis explores the possibilities of tropism-analogy as strategy for tackling some of these diverse objectives in a generative system. The feasibility of addressing heterogeneous goals with a computerizable design system is established by reviewing the role of rule-based strategies in vernacular tradition and the possibilities of analogies in recent generative methods. Then, the concept of tropism is analysed in depth, starting from its origins to its manifestation in a broad range of disciplines. This analysis leads to the definition of tropism as a ‘process of turn’ that enables purposeful connections between a system and its environment, an invariant property that may result in different levels of adaptation. These generalized conditions are used as conceptual foundation to explore analogical connections between divergent dimensions of architectural problems, and to define a feedback-enabled generative system that uses tropism-inspired rules in tackling contrasting design objectives. This system is implemented as a proof-of-concept for the Chilean social housing program, where is used to generate façade prototypes that respond simultaneously to thermal comfort and formal expression criteria. The outcomes of this thesis suggest that tropism-analogy can be used in tackling heterogeneous façade objectives and, therefore, to define novel design methods to explore goal-integration in computer-based generative architecture systems.

summary	The international architecture of the past decade adds parametric design to the project as a new variable dynamic strategy in the design process. Generative patterns meet a way of achieving parameterization from the computational geometry. The experimental developments of URDIR.Lab (FADU-UNL) group, ranges from: the current projective exercises with dynamic materials and forms to the development of simple formulas applied to everyday practice. The proposed challenge is to merge the local available technological resources - pre-industrial and industrial - with the ideation systems of post-industrial technologies.

title	Parametric Design with Standard Elements for Non-Standard Architecture

summary	The development of non-standard architecture is often combined with the use of non-standard elements. But for economical or sustainable reasons, the use of standard elements may be particularly useful. The introduction of standard elements adapted to geometries far from parallelepipeds and freely designed raises a specific problem. The aim of this paper is to explore some ways offered by computing tools in order to help architects in the design process of non-standard shapes using standard elements. An approach is proposed for a specific typology of systems composed of constant length elements. The method used herein is based on parametric modeling associated with constraint resolution algorithms. (short abstract because full paper already written)

doi	https://doi.org/10.52842/conf.acadia.2011.292
summary	This paper proposes Buckminster Fuller’s concept of pattern integrity as a context for understanding computational techniques in environmentally responsive design. We argue that successful integration in this context requires a continuous design medium that allows for heterogeneous, mutable techniques and models. This model of integration is demonstrated by reference to a current project for a large canopy structure in Singapore with specific focus on issues of environmental mediation, object-oriented programming for CAD environments, and functional programming techniques within parametric modeling systems. We discuss the applicability of these novel integrative approaches to wider problems in computational design.

doi	https://doi.org/10.52842/conf.acadia.2011.318
summary	This paper presents continuing research on responsive systems in architecture; the ability of architectural systems to change certain properties in response to their surrounding environmental pressures. While doing so, it shifts from current and past examples of mechanical approaches of adaptation, towards biological paradigms of seamless material integration. Looking at biological mechanisms of growth and focusing on the material make-up behind them, the research proposes the exploration of material systems in a two-fold interrelated manner: firstly, through passive material systems of variable elasticity, and secondly through the embedment of smart materials with shape-changing properties. The combination of the two is aiming at architectural systems of functional versatility.Through an interdisciplinary approach, the paper examines the following questions: Is it possible to envisage structures that share the principles of adaptation and response of living organisms? What are the technological challenges faced when designing self-actuated responsive interfaces? Which is the conceptual framework for understanding and investigating complex adaptive and responsive systems? By exploring and synthesizing theories and tools from material science, bioengineering and cybernetics the aim is to inform architectural interfaces able to enhance interconnectivity between the man-made and the natural. Focusing on the self-organization of material systems the intention is to suggest architectural interventions, which become sub-systems of their ecological milieu. The emphasis therefore is placed not on architectural formalism, but on how we can define synthetic environments through constant exchanges of energy, matter and information.

summary	The paper describes and discusses a generic approach for generative design by Turing Machines operating on a three-dimensionally folded surface. It is part of an on going research on concurrent cooperative design processes in architecture. During the development of systems for simplified generic interaction in spatial design, it turned out that the basic operations are applicable to be processed by non-sophisticated automata. If the spatial configuration is interpreted as the medium for an ordinary state machine, the whole system adds up to a kind of Turing Machine. Since 2D-Turing Machines are often referred to as “turmites”, and the proposed system is based on a yet three-dimensional folded, but still twodimensional surface - the automaton will be called “Turmitect”.

title	Building Skin Intelligence: A parametric and algorithmic tool for daylighting performance design integration
source	ACADIA 11: Integration through Computation [Proceedings of the 31st Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA)] [ISBN 978-1-6136-4595-6] Banff (Alberta) 13-16 October, 2011, pp. 170-177
doi	https://doi.org/10.52842/conf.acadia.2011.170
summary	The research presents a methodology and tool development which delineates a performance-based design integration to address the design, simulation, and proving of an intelligent building skin design and its impact on daylighting performance. Through the design of an algorithm and parametric process for integrating daylighting performance into the design phase an automated configuration evaluation is achieved. Specifically the tool enables design exploration of semi autonomous and fully autonomous configurations of an exterior building envelope louver system. The research situates itself in the field of intelligent building skins and adds to the existing solutions a validation of systems with interdependent louvers of varying tilt angles. The system is designed to respond to dynamic daylighting conditions and occupants’ preferences. Within the framework of this study, Grasshopper, Rhino, Galapagos and DIVA, are linked and coded into one integrated process, facilitating design optioneering with near real time feedback. The paper concludes with a description of the tool set’s extensibility, future incorporation of domain integration, and conflation of natural and physical system interaction and complexity.

summary	The paper presents performance oriented approaches to digital form finding which stems from the lines of research on performance and morphogenesis in architectural design. The main contribution to the earlier research is threefold; it examines the potential of the presented design processes to integrate interdisciplinary approach based on the use of simulation tools by architects or direct data exchange between simulation tools and design. Secondly, it explores new methods to generate initial architectural form based on performance information that apply to both building scale and urban scale, and lastly, it develops the theoretical framework on the ramifications of employing simulation technology and techniques in architectural design.

summary	Matter and information; information and matter. A puzzle unveiled little by little. Hardly surprising since every atom, molecule, and basic particle in the universe registers bits of information. All interactions between these components, inert and alive, owe their existence to matter’s intrinsic ability to process information. Such aptitude explains how complex systems can arise from fundamentally simple organizational laws. In fact, the world’s almost infinite material combinations, viable through such few basic elements, are one of the most visible expressions of these capabilities. Triggered by the developments in quantum physics across the twentieth century, our understanding of material processes radically shifted our impressions of the world. For decades our scales of perception and manipulation have continued to expand into almost unfathomable boundaries. Yet, the study of the interdependencies between matter and information is still fundamentally part of the sciences and engineering. Only just recently did architecture venture into this inherently intricate field. The subsequent set of papers here presented posit fundamental interrogations of potential interdependencies between matter and information. Without fear to confront the obstacles of delving into a largely unexplored field of architecture, these researchers forge new frontiers of interrelating computational parameters to multi-physics in the complex settings of architectural scale. Unlike other epistemologies, architecture cannot be reduced to a single scale of exploration. We can neither restrict scalar boundaries (i.e., nano to micro), nor reduce morphologies to simplify the processing of multiple physics without compromising the design problem. By default, it is more difficult to conceptually and numerically articulate the abstract and numerical criteria of complex geometries and material variables.

title	Tree facades: Generative modelling with an axial branch rewriting system

summary	The methods and algorithms of generative modelling can be improved when representing organic structures by the study of computational models of natural processes and their application to architectural design. In this paper, we present a study of the generation of branching structures and their application to the development of façade support systems. We investigate two types of branching structures, a recursive bifurcation model and an axial tree based L-system for the generation of façades. The aim of the paper is to capture not only the form but also the underlying principles of biomimicry found in branching. This is then tested, by their application to develop experimental façade support systems. The developed algorithms implement parametric variations for façade generation based on natural tree-like branching. The benefits of such a model are: ease of structural optimization, variations of support and digital fabrication of façade components.

title	Visual Dataflow Modelling: A Comparison of Three Systems

summary	Visual programming languages enable users to create computer programs by manipulating graphical elements rather than by entering text. The difference between textual languages and visual languages is that most textual languages use a procedural programming model, while most visual languages use a dataflow programming model. When visual programming is applied to design, it results in a new modelling approach that we refer to 'visual dataflow modelling' (VDM). Recently, VDM has becoming increasingly popular within the design community, as it can accelerate the iterative design process, thereby allowing larger numbers of design possibilities to be explored. Furthermore, it is now also becoming an important tool in performance-based design approaches, since it may potentially enable the closing of the loop between design development and design evaluation. A number of CAD systems now provide VDM interfaces, allowing designers to define form generating procedures without having to resort to scripting or programming. However, these environments have certain weaknesses that limit their usability. This paper will analyse these weaknesses by comparing and contrasting three VDM environments: McNeel Grasshopper, Bentley Generative Components, and Sidefx Houdini. The paper will focus on five key areas: * Conditional logic allow rules to be applied to geometric entities that control how they behave. Such rules will typically be defined as if-then-else conditions, where an action will be executed if a particular condition is true. A more advanced version of this is the while loop, where the action within the loop will be repeatedly executed while a certain condition remains true. * Local coordinate systems allow geometric entities to be manipulated relative to some convenient local point of reference. These systems may be either two-dimensional or three-dimensional, using either Cartesian, cylindrical, or spherical systems. Techniques for mapping geometric entities from one coordinate system to another also need to be considered. * Duplication includes three types: simple duplication, endogenous duplication, and exogenous duplication. Simple duplication consists of copying some geometric entity a certain number of times, producing identical copies of the original. Endogenous duplication consist of copying some geometric entity by applying a set of transformations that are defined as part of the duplication process. Lastly, exogenous duplication consists of copying some geometric entity by applying a set of transformations that are defined by some other external geometry. * Part-whole relationships allow geometric entities to be grouped in various ways, based on the fundamental set-theoretic concept that entities can be members of sets, and sets can be members of other sets. Ways of aggregating data into both hierarchical and non-hierarchical structures, and ways of filtering data based on these structures need to be considered. * Spatial queries include relationships between geometric entities such as touching, crossing, overlapping, or containing. More advanced spatial queries include various distance based queries and various sorting queries (e.g. sorting all entities based on position) and filtering queries (e.g. finding all entities with a certain distance from a point). For each of these five areas, a simple benchmarking test case has been developed. For example, for conditional logic, the test case consists of a simple room with a single window with a condition: the window should always be in the longest north-facing wall. If the room is rotated or its dimensions changed, then the window must re-evaluate itself and possibly change position to a different wall. For each benchmarking test-case, visual programs are implemented in each of the three VDM environments. The visual programs are then compared and contrasted, focusing on two areas. First, the type of constructs used in each of these environments are compared and contrasted. Second, the cognitive complexity of the visual programming task in each of these environments are compared and contrasted.
