title	Affordable Computation for Architecture
source	Hybrid Spaces of the Metaverse - Architecture in the Age of the Metaverse: Opportunities and Potentials [10th ASCAAD Conference Proceedings] Debbieh (Lebanon) [Virtual Conference] 12-13 October 2022, pp. 415-433
summary	Current architectural requirements prioritize the need to minimize the ecological footprint. By taking advantage of computational design approaches like Algorithmic Design (AD), architects can enhance their design processes with analysis, optimization, and visualization mechanisms, which are critical to explore design solutions that meet this need. However, these mechanisms are also highly time- and resource-consuming, often implying a quality tradeoff or the acquisition of High-Performance Computing (HPC) machines. The latter are not yet affordable for most design studios but, fortunately, they can be contracted as a service. This paper evaluates the impact of computation as a service in architecture and, more specifically, the remote use of HPC for AD, with the aim of reducing the time and costs associated with computationally expensive processes. A set of experiments were made involving analysis, optimization, and rendering of a selected case study. Results indicate that HPC services are advantageous, particularly when performing embarrassingly parallelizable tasks such as rendering. However, some challenges remain, namely the required expertise.

title	Programming Languages For Generative Design: A Comparative Study
source	International Journal of Architectural Computing vol. 10 - no. 1, 139-162
summary	In the field of Generative Design (GD), Visual Programming Languages (VPLs), such as Grasshopper, are becoming increasingly popular compared to the traditional Textual Programming Languages (TPLs) provided by CAD applications, such as RhinoScript. This reaction is explained by the relative obsolescence of these TPLs and the faster learning curve of VPLs. However, modern TPLs offer a variety of linguistic features designed to overcome the limitations of traditional TPLs, making them hypothetical competitors to VPLs. In this paper, we reconsider the role of TPLs in the design process and we present a comparative study of VPLs and modern TPLs. Our findings show that modern TPLs can be more productive than VPLs, especially, for large-scale and complex design tasks. Finally, we identify some problems of modern TPLs related to portability and sharing of programs and we propose a solution.

title	Emerging designing processes: The use of Digital Design and Rapid Prototyping applied in University Extension
source	SIGRADI 2015 [Proceedings of the 19th Conference of the Iberoamerican Society of Digital Graphics - vol. 2 - ISBN: 978-85-8039-133-6] Florianópolis, SC, Brasil 23-27 November 2015, pp. 558-563.
summary	This paper is about the experience to show the possibilities of the Algorithm Aided Design to a community of students and Professors that actually uses Computed Aided Design, but just for drawings, not for a full digital process. This community is hosted at Belas Artes de S?o Paulo, who in February of 2015, opened up its first Digital Fabrication Laboratory, but people there didn’t have a good idea of what it could be, beyond scale models. It shows that the new theory that supports new digital paradigms in architecture and design was the job acquired for a research group.

title	Dimensional mass customization of a flexible furniture system
source	SIGraDi 2020 [Proceedings of the 24th Conference of the Iberoamerican Society of Digital Graphics - ISSN: 2318-6968] Online Conference 18 - 20 November 2020, pp. 137-142
summary	This paper presents the development of a framework to investigate possible intersections between mass customization and flexibility in the furniture scale, based on the notion of complex modularity. The conceptual framework was implemented with parametric design as a prototypical furniture system, which allows dimensional customization and digital fabrication in reduced scale. The system was evaluated through workshops that simulated pre-configuration and reconfiguration layouts in a study room. Results showed that embedding complex modularity into furniture elements and defining measurement intervals contributed to the flexibility of the mass customized alternatives, providing the emergence of unexpected layout compositions and furniture uses.

summary	Good visualization mechanisms offer architects, and their clients, a better grasp of how their designs are going to turn out when built, and the experience one might have inside the constructions. This also helps the architect orient the design in a more informed manner. However, typically used modeling tools do not offer satisfactory visualization solutions. The operations available to view and navigate through the 3D space are flawed in terms of speed, interactivity, and real-time rendering quality. To solve this issue, we propose the coupling of a portable algorithmic design framework with a Game Engine (GE) to support interactive visualization of architectural models and increase the rendering performance of the framework. We explain in detail this integration, and we evaluate this workflow by implementing a case study and comparing the performance of the GE to architectural modeling tools.

summary	Since the great popularity of smartphones and tablets, many applications have been developed to create digital panoramas. However, its focus is turned for the seamless of the pictures and not what we can explore and understand of its different subjects. This article intends to investigate the use of a new concept of an app for digital panoramas. We assume that Panoramapp! can broaden the understanding the history of the cities by its panoramas and panoramic views, an alternative way to develop an iconographic hyper document of the central area of the city of Rio de Janeiro.

title	Teaching computer science for architecture - A proposal
source	FUTURE TRADITIONS [1st eCAADe Regional International Workshop Proceedings / ISBN 978-989-8527-03-5], University of Porto, Faculty of Architecture (Portugal), 4-5 April 2013, pp. 95-104
summary	Computers have profoundly changed the way architects work. Computer science is nowadays recognized as one of the fundamental sciences that must be taught in architecture. Unfortunately, computer science is usually taught just like Physics or Probability Theory, without really preparing the students for the tremendous impact that it will have in architecture in the near future. In this paper we analyze that impact and we discuss some of the approaches that are currently being used for teaching computer science in architecture. Our main contribution is a proposal for teaching computer science in architecture using the principles of functional programming and, particularly, higher-order programming, while avoiding being dependent of specific CAD tools. We claim that this approach gives the student the ability to think, design, and explore designs more effectively than using previous approaches. We validate our claims using data from our own teaching experience during the last five years.

title	Improving Generative Design by Combining Abstract Geometry and Higher-Order Programming

summary	Generative Design (GD) involves the use of algorithms that compute designs. To take advantage of the computational power of computers, these algorithms must be implemented in a programming language. Although most programming languages have the same computational power, they have very different expressive powers. In this paper we focus on exploring the expressive power of languages and we argue that (1) the ability to use abstract geometry as input and (2) the use of higher-order programming dramatically simplifies the implementation of GD algorithms. We illustrate these concepts using a large and complex example that was developed as a case-study.

summary	Nowadays, many buildings need to accommodate large numbers and/or large concentrations of people. Despite the efforts to produce building designs that can safely evacuate occupants, accidents continue to happen with dramatic consequences. This happens, in part, because of the difficulty in anticipating the consequences of design decisions regarding building's evacuation performance. In order to improve the situation, one needs to resort to evacuation simulation tools. These, however, have two problems: (1) they require analytic building models that are difficult to produce manually, and (2) they tend to focus on evacuations under non-emergency conditions, where panic phenomena is not present. In this paper, we propose a combination between algorithmic design and different evacuation simulators that allows for the quick simulation of many design variations.

summary	Nowadays, programming is quickly becoming part of the tool chest of the modern architect. Unfortunately, the architecture curriculum does not yet recognize its importance and usefulness or uses inadequate languages or programming environments to teach it. In this paper we argue that it is necessary to include computer science courses in the architecture curriculum and that these courses should be tailored to the needs of the architects. To help achieve this goal, we propose VisualScheme, an interactive programming environment that accompanies the architect from the learning phases to the advanced uses and that can be explored in pedagogic, research, and industry settings.

summary	Design is characterized by change. Nowadays, addressing change in design requires enormous efforts, particularly, when the designer is exploring different solutions or when it is necessary to adapt the design to evolving constraints. This paper discusses the potential of Generative Design to help designers handling change, namely in the generation of several alternative design solutions. We propose a programming-based approach that, although requiring an initial investment, dramatically reduces the efforts of design modification. We evaluate the approach in a case study and we show that it is cost-effective in the development of an architectural design.

summary	In this paper we compare visual and textual programming languages for generative design. We argue that, in the past, this comparison has been flawed and that it is now time to reconsider the potential of the textual programming paradigm but using modern programming languages and development environments specifically targeted to the generative design domain. We present VisualScheme as a prime example of such language and we compare it with the most used visual programming language in the generative design field.

summary	Today’s architectural design is changing rapidly through the scope of new digital design tools (software like parametrical modelers) on the one and the use of digitally controlled fabrication techniques (hardware like 3D CNC-milling) on the other side. However the full intuitive and experimental potential of the software has to be accessed through the sometimes limiting bottleneck of the traditional mouse-screen user interface although alternative interaction methods like multi-touch became available. This paper focuses on extending the usability and spontaneity in a common architectural design process using an iPad as an external hardware controller.

summary	Music and architecture share not only phenomenological similarities in relation to their characteristics - like volume, timbre, tone pitch, instrumentation vs. geometry, materiality, light ambiance or perspective - but imply as well comparability in the process of creation. The investigation of digital tools that cross borders between music and architecture was the starting point for the research project „Mixer Modeling“. Against this background the paper discusses the transformation of a musical composition controller into an intuitive design tool for the generation of architectural geometries. In the same amount that the use of a MIDI-controller increases the degrees of freedom for the simultaneous activation of various parameters the definition of geometric dependencies on the level of visual programming become more important for the resulting geometry.

summary	The expanding use of computers in developing countries - alongside the results of surveys revealing dramatic social indicators for illiteracy - demands careful analysis of the necessary education and training for people to be able to take part and to survive in the information society.”For a citizen of international society, it is no longer enough to know how to read and write, or to have learned a skill. One must have access to information, know how to look for it and find it, master the usage, organize it, understand its organizational forms and, above all, make appropriate, adequate and effective use of it. “ (Spitz, 2000).
