summary	Venation structures in leaves fulfil both circulatory as well as structural functions within the organism they belong to. A possible digital simulation algorithm for the growth of venation patterns based on the leaf surface has been described by the Department of Computer Science at the University of Calgary.Cell-based growth algorithms to generate surface meshes have been developed by biological and medical scientists as well as artists, in order to gain an understanding of developmental biology or to generate artistic form. This paper suggests the combination of the two algorithms in order to generate the morphologies of leaves and other structures while at the same time generating the corresponding venation system.The resulting algorithm develops large non-manifold mesh structures based on local rules of division of the individual cells. The venation system develops in parallel based on the flow of the plant hormone auxin from those cells towards the start point or petiole of the leaf. Different local behaviours of the cells towards their adjacent neighbours, towards their rules of division and towards the rules of developing veins have been investigated. The eventual aim of the algorithms is their application as tools to develop architectural and structural morphologies.

title	Angiogenesis as a model for the generation of load-bearing networks
source	International Journal of Architectural Computing vol. 15 - no. 1, 18-36
summary	This research suggests an algorithm to generate structural networks based on discreet elements for given locations of support points and point loads. Previous research attempted to achieve this by using a computational growth simulation of venation systems, which form the structure of leaves. However, such networks always start from a single point and therefore cannot be used to form arches or beams. In order to generate networks that are based on two or three support points, an algorithm has been developed that is inspired instead by angiogenesis, the process by which vascular systems develop. The algorithm is based on a spring system with a variable network graph that connects the support points and is pulled upwards and split sideways into multiple veins by a given set of load points. The algorithm has been used to grow architectural structures. Different networks have been tested using finite element analysis and compared with both venation and column-and-beam structures. The angiogenesis networks as well as the venation network are shown to perform well and may be suitable as architectural structural systems.

title	Double-Curved Form Approximation with Identical Discrete Panel Geometries

summary	To reduce the costs of manufacturing multiple moulds for double-curved facade construction, this research suggests a method of approximating the desired envelope with identically formed panel geometries. The panels can then be fabricated by only using two double-curved moulds. In a second step, individual segments are cut out of the identical base geometries. The method has been successfully tested with the construction of a prototype. The result is an intricately textured free-form geometry. The installation was built at a reasonable cost compared to other ways of fabricating double-curved geometry. The strength of the panels was utilised as the sole structural system of the prototype.

summary	This paper presents a methodology for the robotic 3D printing of cellulose and wood shavings with bioplastics for applications in architecture, moulds, or furniture design. The material composition consists of plant fibre, binders, solvents and additives. All of the ingredients are either biodegradable or biocompatible, as in, they naturally occur in the environment. Different material compositions have been explored and tested for their extrusion behaviour, drying and curing behaviour, buildability and final product qualities, resulting in the manufacture of several case-study prototypes as a proof of concept.

summary	This research explores the combination of two different types of algorithms that have so far been treated separately in architectural computational design: recursive subdivision, and differential or cellular growth. The two algorithms appear to act in opposite directions, the first is a refinement going inwards while the latter is growing outwards. However, both algorithms are based on the refinement of mesh geometries by inserting new vertices and faces and can be used in combination. The resulting subdivisional growth can be used to enhance specific geometric traits of either recursive subdivision or cellular growth at different scales or in different sections of the design object. The resulting geometries have been explored through case studies that utilize those possibilities.

title	Engineering Design Tropisms. Utilization of a bamboo-resin joint for voxelized network geometries
doi	https://doi.org/10.52842/conf.acadia.2018.322

summary	We propose the combination of the traditional construction material bamboo with a novel epoxy-resin joint. The joint forms a bending-resisting connection that eliminates the need for diagonal members. This allows its utilization along rectangular grids as was tested with the design of a prototype structure that occupies a voxelized space. The design process used an agent-based simulation to mediate between design intent, site and structural considerations. The prototype was constructed with a robotic milling of the components and forms a successful application of the joints and design methodology.

doi	https://doi.org/10.52842/conf.acadia.2019.542
source	ACADIA 19:UBIQUITY AND AUTONOMY [Proceedings of the 39th Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) ISBN 978-0-578-59179-7] (The University of Texas at Austin School of Architecture, Austin, Texas 21-26 October, 2019) pp. 542-553
summary	Discrete computational growth simulations, such as Cellular Automata of Diffusion Limited Aggregation, appear often to be difficult to use for architectural design as their geometric outcomes tend to be difficult to control. On the contrary, free-form growth simulations such as Differential Growth or cell-based growth algorithms produce highly complex geometries that are difficult to construct at a larger scale. We, therefore, propose a methodology of discretized free-form Cellular Growth algorithms in order to utilize the emerging qualities of growth simulations for a feasible architectural design. The methodology has been tested within the framework of a workshop and resulted in the efficient construction of a large physical prototype.

title	Ontologies and Shape Grammars - A Relational Overview Towards Semantic Design Systems
doi	https://doi.org/10.52842/conf.ecaade.2016.2.305
source	Herneoja, Aulikki; Toni Österlund and Piia Markkanen (eds.), Complexity & Simplicity - Proceedings of the 34th eCAADe Conference - Volume 2, University of Oulu, Oulu, Finland, 22-26 August 2016, pp. 305-314
summary	This paper provides an overview on the relation between computational ontologies and shape grammars regarding the development and production of multi-purpose Semantic Design Systems. The objective of the author's ongoing research is to assist the creation of generative design systems, applicable to design processes in general. Shape grammar rules and ontologies in these systems will be focusing on abstract, generic rules and generic descriptions. When combined through contextually specified relations, these assume semantic expressions and should be able to produce meaningful results.We collect here a short state of the art of the research developed in the fields of architecture, urbanism and computer science in the past ten years regarding the use of knowledge bases (ontologies) combined with generative design systems (with a particular focus on shape grammars). We expect to provide both insight about architectural and urban typologies and the production of meaningful designs using automated generative design systems.

summary	This paper will explore the hypothesis that Mixed Reality is a differentiated media and credible framework for the generation, fabrication and communication of projects that are explicitly engaged in design research. This will be shown through a critical presentation of three built and unbuilt projects by Building w/immaterials in the domains of architecture, installation and education. These projects will demonstrate the creative and theoretical application of Mixed Reality from within the differentiated social system of Architecture. While the majority of research into Mixed Reality seems to concern its technical aspects, we will explore its application as a creative system for project development, realization and diffusion.

source	Computer Graphics and Image Processing. 1976. vol. 5: pp. 68-105 : ill. includes bibliography
summary	The problem of building a computer-searchable data representation for a complex image and the effect of representation on algorithms for scene segmentation into regions is considered. A regular decomposition of picture area into successively smaller quadrants is defined, which involves logarithmic search. This hierarchical search and resulting picture representation are shown to enable rapid access of image data without regard to position, efficient storage, and approximate structural descriptions of constituent patterns. Examples involving solid geometrical objects and alphabetic characters are given

source	SIGraDi 2010_Proceedings of the 14th Congress of the Iberoamerican Society of Digital Graphics, pp. Bogotá, Colombia, November 17-19, 2010, pp. 26-29
summary	Collaboration and information exchange are the primary tactics for a globally connected locally produced design - through - production process. With strategic industry partners, Ball State University students test knowledge through real - world applications. While the open access to knowledge in the global environment is critical, it is also imperative to consider the ethic of production and regionally specific conditions under which work is enabled. To this end, the paper will reveal specific design - throughproduction industry - partner collaborations, while exploring the regional implications of making locally, and consider the role of the university to serve as a local catalyst for change in a shifting global economic climate.

title	Making Digital Architecture: Historical, Formal, and Structural Implications of Computer Controlled Fabrication and Expressive Form
doi	https://doi.org/10.52842/conf.ecaade.2001.239
source	Architectural Information Management [19th eCAADe Conference Proceedings / ISBN 0-9523687-8-1] Helsinki (Finland) 29-31 August 2001, pp. 239-244
summary	Digital output from computer modeling represents a significant new method for visualization and fabrication of architecture. The ability to move directly from three-dimensional modeling to real three-dimensional output challenges the need for traditional means of representation such as plan, section, etc. Moreover, the necessity for conversion of architectural intentions into a code (construction documents, shop drawings, etc.) to be translated by the contractor will also be tested with these new potentials in fabrication. This subjugation of traditional forms of representation and fabrication has serious implications for architectural design process and production. The intention of this paper is to scrutinize underlying issues inherent in a design process of developing architectural solutions using the computer both as a tool for threedimensional visualization as well as for guiding three-dimensional fabrication. Precedent of historic expressive architectural form (seen through the lens of fabrication) will be presented to lay the foundation for the examination of new fabrication techniques and structural concerns for computer generated expressive forms. A series of rapid prototype studies from a digital architecture seminar will also be analyzed to outline the need for developing visualization/fabrication process ideas and research into methods for making digital architecture.

title	Augmented Vision: Digital Devices and Post-processing for Experiential Learning
source	SIGraDi 2005 - [Proceedings of the 9th Iberoamerican Congress of Digital Graphics] Lima - Peru 21-24 november 2005, vol. 2, pp. 714-719
summary	Today, digital devices and post-processing provide for rich mediated observations of places. When we observe the natural world through a digital lens, it alters perception and augments our understanding. Digital devices affect the observing reality through a bias of digital laws, thus participating by revealing layers of information concealed within the captured scene. This paper outlines strategies for digitally augmenting our innate powers of observation and facilitating critical experiential learning through digital visual notation. Digitally augmented observation techniques were tested during student and professor related travel/study with Ball State University. Examples of time-based motion capture such as serial digital photography, post processed image manipulation, and digital video/still collage with multimedia narrative will be used to illustrate how digitally enhanced augmented vision techniques render observation of the everyday world in new terms. Additionally, the paper points to a trajectory for future digital notes scholarship by examining the potential for innovative new pedagogies, and situating the discourse in relation to an existing body of scholarship on traditional visual notes.

source	SIGraDi 2009 - Proceedings of the 13th Congress of the Iberoamerican Society of Digital Graphics, Sao Paulo, Brazil, November 16-18, 2009
summary	Innovation through digital design in contemporary practice has led to completely new ways of designing and making architecture. To prepare for these innovative opportunities, students are turning to alternative skill sets than those traditionally gained in an architectural curriculum. This paper argues that we must reconstruct our architectural curricula in order to better prepare students for a shifting professional landscape. While current material-based production realities of translating digital design into built form have much in common with modernist traditions, exercises, sequences, and collaborative opportunities in schools should pass through a relevant lens examining the true potential of working with the information age.

summary	Parameters within a highly collaborative design-through-production process range from a very broad set of influences. To address the conundrum of selecting operational logics, we begin searching for form genesis with an examination and reproduction of the past in order to both restore and formulate a contemporary response to an existing ceiling within an iconic space, designed in 1964 by Alexander Girard in the atmosphere of significant architectural design influences radiating from Columbus, Indiana. Methods learned from analysis of original production are used, and synthesized as guiding principles in the design-through-production process of contemporary work.

summary	Digital architecture contingent upon a conversation between digital visualization and digital production deploys an iterative and seamless process-oriented design development. Feedback loops are integral to this process/product, and thus require extensive management of complex visual and data related information. While much attention has been paid to fabrication and serial customization of digital architecture, very little discussion has been forwarded about innovations in visualizing and representing the design data integral in this feedback loop. This paper will examine innovative representational devices such as the matrix, sectioning, layering, and bracketing as new forms of organizing and visualizing complex data intent upon communicating multiple levels of operations during the fabrication process.

title	Visualizing the Operative and Analytic: Representing the Digital Fabrication Feedback Loop and Managing the Digital Exchange
source	International Journal of Architectural Computing vol. 4 - no. 3, 79-97
summary	Digital architecture is process-based and reliant upon a conversation between digital visualization, analysis, and production. With the complexity of information generated in process-based digital practices, we need to effectively manage and exchange the information. Feedback loops are integral to this process/product, and thus require extensive management of complex versions of visual and data related information. Quite a lot of scholarly attention has been focused upon highlighting innovative projects using digital fabrication and serial customization. However, there is a scarcity of scholarly work about innovations in visualizing and representing the design data integral in this feedback loop. This paper will examine innovative representational devices such as the matrix, sectioning, layering, bracketing, nesting, and other new forms of organizing, visualizing, analyzing, and simulating complex data, intent upon communicating multiple levels of operations during the design and fabrication process. With a rigorous taxonomy of operative and analytic devices for process-based digital design development, we can begin to outline a trajectory for future evolutions in practice. This writing is an attempt to make a few steps in this direction, and demonstrate some of these new representational ideas in practice.
