title	Decomposition of a Multi-Cell Complex -- A Problem in Physical Design
source	November, 1974. 8 p. : ill., diagrams. includes bibliography
summary	A method for decomposition of a multi-cell complex is suggested. The algorithm is based on successive splitting steps. At each step the set of elements is subdivided into at least two subgroups. The decomposition is carried out by translating the incidence matrix into a directed network and then applying a minimum-cut algorithm for finding the optimum cut-set. Various architectural constraints are incorporated in the decomposition algorithm. An example of an elementary school design problem is given to illustrate the suggested algorithm

title	Reimagining Gego: Geometrical Reconstruction of Nubes, an Undocumented and Lost Sculpture from 1974

summary	This paper describes a method to understand and digitally reconstruct two sculptures by Gertrud Goldschmidt, a German-born, Venezuelan artist also called Gego. Gego is best known for her series of works called “Reticuláres”. These three-dimensional and open installations, mostly hanging freely in space, are playing with the concept and perception of space as well as challenging the definition of the traditional sculpture. The paper aims to generate information about two specific structures called “Nubes” (Clouds for Spanish) to assist in a physical reconstruction for a larger exhibition about Gego and to contribute to understanding Gego’s work process. Originally, the structures were suspended from a building's ceiling as an art installation in Caracas, 1974. There are three main challenges for this reconstruction: (1) The installations exhibit a complex three-dimensional geometry. (2) Scant drawings and photographs exist. (3) Gego might not have followed her initial drawings completely when building Nubes physically, because of the mentioned complexity and due to the light and bendable material properties of the employed material. The paper describes a computational process that recreates the object’s geometry in four steps: (1) Analyse all existing media of the structure. (2) Translate found information to the digital environment of Grasshopper. (3) Use a physical simulation to derive the end state of the hanging structure. (4) Optimize and tune the simulation with an optimization algorithm for better results. This paper demonstrates the usefulness of computational tools for reconstructing lost sculptures with little documentation. In this case, these tools allow a more accurate reconstruction and contribute to a fuller understanding of the design and realization process of Gego's Nubes.

title	Texture and Reflection in Computer Generated Images
source	Communications of the ACM 19 10 542-547
summary	In 1974 Catmull developed a new algorithm for rendering images of bivariate surface patches. This paper describes extensions of this algorithm in the areas of texture simulation and lighting models. The parametrization of a patch defines a coordinate system which is used as a key for mapping patterns onto the surface. The intensity of the pattern at each picture element is computed as a weighted average of regions of the pattern definition function. The shape and size of this weighting function are chosen using digital signal processing theory. The patch rendering algorithm allows accurate computation of the surface normal to the patch at each picture element, permitting the simulation of mirror reflections. The amount of light coming from a given direction is modeled in a similar manner to the texture mapping and then added to the intensity obtained from the texture mapping. Several examples of images synthesized using these new techniques are included.

summary	Gaming software has a history of fostering development of economical and creative methods to deal with hardware limitations. Traditionally the visual representation of gaming software has been a poor offspring of high-end visualization. In a twist of irony, this paper proposes that game production software leads the way into a new era of physical digital ornament. The toolbox of the rendering engine evolved rapidly between 1974-1985 and it is still today, 20 years later the main component of all visualization programs. The development of the bump map is of particular interest; its evolution into a physical displacement map provides untold opportunities of the appropriation of the 2D image to a physical 3D object.To expose the creative potential of the displacement map, a wide scope of existing displacement usage has been identified: Top2maya is a scientific appropriation, Caruso St John Architects an architectural precedent and Tord Boonje’s use of 2D digital pattern provides us with an artistic production precedent. Current gaming technologies give us an indication of how the resolution of displacement is set to enter an unprecedented level of geometric detail. As modernity was inspired by the machine age, we should be led by current technological advancement and appropriate its usage. It is about a move away from the simplification of structure and form to one that deals with the real possibilities of expanding the dialogue of surface topology. Digital Ornament is a kinetic process rather than static, its intentions lie in returning the choice of bespoke materials back to the Architect, Designer and Artist.

summary	Gaming and visualisation software has a history of developing economical and creative methods to deal with hardware limitations. Traditionally the visual representation of gaming has been a poor offspring of high-end architectural visualisation. In a twist of irony, the paper proposes that game production software leads the way into a new era of physical digital ornament. The toolbox of the rendering engine evolved rapidly between 1974-85 and it is still today 20 years later the main component of all visualisation programs. The development of the bump map is of particular interest; its evolution into a physical displacement map provides untold opportunities in the appropriation of the 2D image to a physical artifact. Contemporary Architects in tandem have been mapping to the façade a new era of complex three-dimensional sculptural representation. The Architect, Designer and Artist now have the opportunity to appropriate the image map and use advanced visualisation technologies in the application of digital ornament.

title	EMO-Space: A Computational Model for Interaction between Emotions and Space
source	Nicole Gardner, Christiane M. Herr, Likai Wang, Hirano Toshiki, Sumbul Ahmad Khan (eds.), ACCELERATED DESIGN - Proceedings of the 29th CAADRIA Conference, Singapore, 20-26 April 2024, Volume 3, pp. 401–410

summary	Architectural space can trigger emotion (Zumthor, 2006). Psychologists Mehrabian and Russell (1974) proposed PAD model, presenting eight emotions as a means for psychologists to self-assess the emotional conditions of human experience and to provide people with a way to conceptualize the impact of cognitive structure. The Brain-Computer Interface (BCI) combines with computer operations to decode and calculate different brain waves generated by human emotions, supporting the convenience and wisdom of human life. The integration of the PDA model and BCI technology will offer an understanding of the interactive relationships between space and emotion. The purpose of this research is to construct a computational model called EMO-Space, which can autonomously support space interaction through the understanding of human emotions. Based on the PAD model, the integration of BCI, the mechanism of emotional transformation, and the control of message transmission are explored. Subsequently, the computational model is proposed and simulated. EMO-Space will provide the basis for the intelligence of emotional space in the future, such as in elderly care and spatial healing.
