In this article, we present a procedure to derive algebraic descriptions from geometric descriptions of trimmed hyperbolic paraboloid (or ‘hypar’) surfaces. We contextualise this procedure historically, and we illustrate its application using the 1958 Philips Pavilion by Le Corbusier and Iannis Xenakis as a case study. The procedure uses parametric modelling and computational optimisation to converge on close algebraic approximations of hyperbolic paraboloid geometry through a successive breakdown of vast search spaces. It departs from coordinate data of three or four vertices of a geometrically described hyperbolic paraboloid and yields the surface’s two quadratic coefficients, the coordinates of its centroid location and the rotation angles of its spatial orientation. The procedure exemplifies the under-explored analytical (as opposed to generative) use of computational optimisation and parametric modelling in the field of architectural computing.

The role of optimization-based design exploration in early-stage architectural design has been increasingly recognized and valued. It has been widely considered an effective approach to achieving performance-informed and performance-driven design. Nevertheless, there is little research into how such design exploration can be adapted to various early-stage architectural design tasks. With this motivation, this paper revolves around a computer-aided design workflow for early-stage building massing design optimization and exploration while presenting three workshop case studies to demonstrate how the workflow can be intertwined with the design process. The design workflow is based on EvoMass, an integrated building massing design generation and optimization tool in Rhino-Grasshopper. The case study illustrates task-specific applications of the design workflow for synthesizing building design, finding design precedents, and understanding the interrelationship between formal attributes and building performance. The paper concludes by discussing the relevant efficacy of the design workflow for architectural design.

Unmanned aerial vehicle (UAV) technology has overcome the limitations of conventional construction management methods using advanced and automated visualization and 3D reconstruction modeling techniques. Although the mapping techniques and reconstruction modeling software can generate real-time and high-resolution descriptive textural, physical, and spatial data, they may fail to develop an accurate and complete 3D model of the construction site. To generate a quality 3D reconstruction model, the construction manager must optimize the trade-offs among three major software-selection factors: functionalities, technical capabilities, and the system hardware specifications. These factors directly affect the robust 3D reconstruction model of the construction site and objects. Accordingly, the purpose of this research was to apply nine well-established 3D reconstruction modeling software tools (DroneDeploy, COLMAP, 3DF+Zephyr, Autodesk Recap, LiMapper, PhotoModeler, 3D Survey, AgiSoft Photoscan, and Pix4D Mapper) and compare their performances and reliabilities in generating complete 3D models. The research was conducted in an eco-home building at the University of Technology, Malaysia. A series of regression analyses were conducted to compare the performances of the selected 3D reconstruction modeling software in alignment and registration, distance computing, geometric measurement, and plugin execution. Regression analysis determined that among the software programs, LiMapper had the strongest positive linear correlation with the ground truth model. Furthermore, the correlation analysis showed a statistically significant p-value for all software, except for 3D Survey. In addition, the research found that Autodesk Recap generated the most-robust and highest-quality dense point clouds. DroneDeploy can create an accurate point cloud and triangulation without using many points as required by COLMAP and LiMapper. It was concluded that most of the software is robustly, positively, and linearly correlated with the corresponding ground truth model. In the future, other factors involving software selection should be studied, such as vendor-related, user-related, and automation factors.
无人机技术利用先进的自动化可视化和三维重建建模技术，克服了传统施工管理方法的局限性。虽然测绘技术和重建建模软件可以生成实时、高分辨率的描述性纹理、物理和空间数据，但它们可能无法建立准确、完整的施工现场三维模型。为了生成高质量的3D重建模型，施工经理必须优化三个主要软件选择因素之间的权衡:功能、技术能力和系统硬件规格。这些因素直接影响到施工场地和物体的三维重建模型的鲁棒性。因此，本研究的目的是应用九种成熟的3D重建建模软件工具(DroneDeploy、COLMAP、3DF+Zephyr、Autodesk Recap、LiMapper、PhotoModeler、3D Survey、AgiSoft Photoscan和Pix4D Mapper)，并比较它们在生成完整3D模型方面的性能和可靠性。这项研究是在马来西亚科技大学的一座生态住宅建筑中进行的。通过一系列的回归分析比较了所选三维重建建模软件在对准配准、距离计算、几何测量和插件执行方面的性能。回归分析表明，在软件程序中，LiMapper与ground truth model的正线性相关性最强。此外，相关分析显示，除3D Survey外，所有软件的p值均具有统计学意义。此外，研究发现，Autodesk Recap生成了最健壮、质量最高的密集点云。DroneDeploy可以创建精确的点云和三角测量，而无需像COLMAP和LiMapper那样使用许多点。结果表明，大多数软件与相应的地面真值模型具有鲁棒性、正相关性和线性相关性。在未来，应该研究涉及软件选择的其他因素，例如与供应商相关的、与用户相关的和自动化因素。

collaboration between designers and stakeholders by allowing simulations side by side comparisons of performance, form and feedback of multiple design alternatives, leading to more informed design decisions. In their manuscript titled ‘ Resilient by design: informing pandemic-safe building redesign with computational models of resident congestion ’ , Frederick Ortner and Jing Zhi Tay describe a computational design-support tool that was developed in response to safe-distancing measures enforced during the COVID-19 pandemic. The proposed approach adopted a hybrid method for simulating building resident movements based on both pre-determined schedules and likely itineraries. The tool was developed to gain a better understanding of congestion in crowded migrant worker dormitories that experienced high rates of COVID-19 transmission. This study contributes to general understanding of con fi gurational and operational aspects of resilience in the built environment, which is particularly relevant in the context of ongoing global pandemic. The manuscripts selected for this special issue of IJAC under the theme of ‘ Re fl ections ’ offer a diverse collection of topics, methods and applications that are enabled by technological affordances of computational design.

While the design practice in the architecture, engineering, and construction (AEC) industry continues to be a creative activity, approaching the design problem from a perspective of the decision-making science has remarkable potentials that manifest in the delivery of high-performing sustainable structures. These possible gains can be attributed to the myriad of decision-making tools and technologies that can be implemented to assist design efforts, such as artificial intelligence (AI) that combines computational power and data wisdom. Such combination comes to extreme importance amid the mounting pressure on the AEC industry players to deliver economic, environmentally friendly, and socially considerate structures. Despite the promising potentials, the utilization of AI, particularly reinforced learning (RL), to support multidisciplinary design endeavours in the AEC industry is still in its infancy. Thus, the present research discusses developing and applying a Markov Decision Process (MDP) model, an RL application, to assist the preliminary multidisciplinary design efforts in the AEC industry. The experimental work shows that MDP models can expedite identifying viable design alternatives within the solutions space in multidisciplinary design while maximizing the likelihood of finding the optimal design.

If we understand architecture as a three-part system formed by the building, its image, or drawings and images describing buildings, and the critical discourse around architecture, then the texts or ways of speaking about architecture play a key role in understanding the field and its development. By analysing a corpus of around 4.6 million words from texts written between 2005 and 2020 that form a part of critical discourse in computational architecture (understood as the result of the intense digitalization of the field), this paper aims to map ways of speaking about computational architecture. This contributes to architectural theory and might help gain a better understanding of the evolution of the digitalization of construction in general. Findings show that computational architecture is surrounded by a specific way of speaking, hybridized with words from fields such as biology, neuroscience, arts and humanities, and engineering. While some topics such as ‘sustainability’ or ‘biology’ come up consistently in the discourse, others, such as ‘people’ or ‘human’, have periods when they are more and less popular. After highlighting open research questions, the paper concludes by presenting a map of periodic and recurring topics in ways of speaking about computational architecture over the last 15 years, thus tracking and documenting long-term trends, and illuminating patterns in the broader field of digital construction.

The article examines the impact of the virtual public sphere on how urban spaces are experienced and conceived in our data-driven society. It places particular emphasis on urban scale digital twins, which are virtual replicas of cities that are used to simulate environments and develop scenarios in response to policy problems. The article also investigates the shift from the technical to the socio-technical perspective within the field of smart cities. Despite the aspirations of urban scale digital twins to enhance the participation of citizens in the decision-making processes relayed to urban planning strategies, the fact that they are based on a limited set of variables and processes makes them problematic. The article aims to shed light on the tension between the real and the ideal at stake during this process of abstracting sets of variables and processes in the case of urban scale digital twins.

In the oriental practice of art and architecture, and among the regions under their influence, Islamic geometric patterns (IGPs) have been widely used, not only due to aesthetics and decoration but also to make it possible to cover wide flat surfaces, curved surface of domes, and perforated surfaces of window and partitions, with perfectly tessellated shapes. However, with advances in time and technology, these techniques could not connect to the new technologies and benefit from the capacities of digitalization. Recent progress in science and technology tends to open new doors to study geometrical patterns by digitalizing the old ones and developing new variations. This study looks at formal grammar and computer science to introduce a new approach to digital visualization of available IGPs, particularly, star patterns. We investigate the potentials of developing a re-writing system for simulation of IGPs to provide a flexible platform, which allows introducing IGP to CAD/CAM software without previous knowledge on their design or drawing techniques. This methodology allows designers to directly develop various scenarios of IGP applications and implement them on related CAD/CAM tools. Formal language and grammar theories, based on applied mathematics are contributing to the advancements of computer science and digital modeling. They can provide an opportunity to express relational definition and written equivalents of the geometries by using strings and symbols. It is supposed that by using the formal grammar frameworks, certain languages could be developed to visualize IGPs in a machine-friendly way, and consequently, this computational interpretation of IGPs facilitates their application and further developments, for example, regards to digital fabrication. The presented method of IGP visualization is developed as a C#-based add-on for Grasshopper in Rhino3D, one of the main modeling tools used by architects and product designers.

Many digital fabrication machines have potential dangers, for example, sudden fires or projectile debris; thus, architects are generally required to supervise these machines when they employ them to make things. It is unlikely that further mechanization will ever completely eliminate such dangers since they result from unpredictable material processes. Therefore, as digital fabrication machines proliferate throughout architecture schools and practices, architects will find themselves spending increasingly more time supervising them, and waiting. In this paper, I argue that architects should then not only embrace waiting-with digital fabrication machines as a new form of architectural labor, but also begin to explore the ways in which such waiting can be productive. I begin with a critique of many architects’ impatience with digital fabrication processes. I then use the continental philosopher Henri Bergson’s concept of “intuition” to discuss the productive potential of waiting-with. Finally, I use a speculative 3D printing workflow to present additional creative possibilities that can arise if architects intentionally build waiting into digital fabrication processes.

Advancements in multi-agent, autonomous, and intelligent robotic systems over the past decades point toward new design and fabrication possibilities. Exploring how humans and robots can create and construct collectively is essential in leveraging robotic technology in the building sector. However, only by making existing knowledge from relevant technological disciplines accessible to designers can we fully exploit current construction methods and further develop them to address the challenges in architecture. To do this, we present a review paper that bridges the gap between Collective Robotic Construction (CRC) and Human–Robot Interaction (HRI) and defines a new research domain in Collective Human–Robot Construction (CHRC) in the architectural design and fabrication context.
