“…Strengthening design intuition based on rigorous studies and rigorous models of the built environment was, after all, a programmatic aim in the development of space syntax (Hillier and Leaman, 1974;Hillier et al, 1972). The distinctive contribution in the larger field of studies that explore urban design universes through computational models (Duarte and Beirão, 2011;Koenig and Bauriedel, 2009;Koenig et al, 2017;Yang et al, 2013) can be sought in the identification and definition of different principles for the organization of street networks, so as to contribute to the clarification of design aims and design choices.…”

Syntactic types are defined as sets of designs with particular properties. We are specifically interested in the definition of deformed grids, a particular type of street network internal to superblocks. The superblocks under study are surrounded by arterial streets and have traversing local main streets and internal street infills. The argument takes advantage of three kinds of rules or algorithms: generative rules that produce a universe of designs, analytical algorithms that can be applied to the description of properties of interest for each member of the universe, and query or sorting rules that allow us to identify those members of the universe that have particular ranges and combinations of properties of interest. The iterative application of analytical and sorting algorithms assists the transition from an intuitive to formalized definitions of type.

“…Supported operations to virtually build structures such as towers, barrel/crossed-vaults include attachments, cuts, splits, and intersections. More advances regarding the procedural generation of buildings addressing exterior façades or outdoor components can be found in [83][84][85].…”

Procedural Modeling of Buildings Composed of Arbitrarily-Shaped Floor-Plans: Background, Progress, Contributions and Challenges of a Methodology Oriented to Cultural Heritage

Virtual models’ production is of high pertinence in research and business fields such as architecture, archeology, or video games, whose requirements might range between expeditious virtual building generation for extensively populating computer-based synthesized environments and hypothesis testing through digital reconstructions. There are some known approaches to achieve the production/reconstruction of virtual models, namely digital settlements and buildings. Manual modeling requires highly-skilled manpower and a considerable amount of time to achieve the desired digital contents, in a process composed by many stages that are typically repeated over time. Both image-based and range scanning approaches are more suitable for digital preservation of well-conserved structures. However, they usually require trained human resources to prepare field operations and manipulate expensive equipment (e.g., 3D scanners) and advanced software tools (e.g., photogrammetric applications). To tackle the issues presented by previous approaches, a class of cost-effective, efficient, and scarce-data-tolerant techniques/methods, known as procedural modeling, has been developed aiming at the semi- or fully-automatic production of virtual environments composed of hollow buildings exclusively represented by outer façades or traversable buildings with interiors, either for expeditious generation or reconstruction. Despite the many achievements of the existing procedural modeling approaches, the production of virtual buildings with both interiors and exteriors composed by non-rectangular shapes (convex or concave n-gons) at the floor-plan level is still seldomly addressed. Therefore, a methodology (and respective system) capable of semi-automatically producing ontology-based traversable buildings composed of arbitrarily-shaped floor-plans has been proposed and continuously developed, and is under analysis in this paper, along with its contributions towards the accomplishment of other virtual reality (VR) and augmented reality (AR) projects/works oriented to digital applications for cultural heritage. Recent roof production-related enhancements resorting to the well-established straight skeleton approach are also addressed, as well as forthcoming challenges. The aim is to consolidate this procedural modeling methodology as a valuable computer graphics work and discuss its future directions.

“…Part of these tools is functioning fully automatic, generating design solutions requiring no intervention at all by the designer. The Interactive Urban Synthesis Computational Methods [8] are an example focusing on the automatic creation of multiple design scenarios implying null or limited interaction with the designer during the process. Some other tools are semi-automatic, entailing little interaction between software and the user.…”

In urban planning, a common unit of measure for housing density is the number of households per hectare. However, the actual size of the physical space occupied by a household, i.e., a dwelling, is seldom considered, neither in 2D nor in 3D. This article proposes a methodology to estimate the average size of a dwelling in existing urban areas from available open data, and to use it as one of the design parameters for new urban-development projects. The proposed unit of measure, called “living space”, includes outdoor and indoor spaces. The idea is to quantitatively analyze the city of today to help design the city of tomorrow. First, the “typical”-dwelling size and a series of Key Performance Indicators are computed for all neighborhoods from a semantic 3D city model and other spatial and non-spatial datasets. A limited number of neighborhoods is selected based on their similarities with the envisioned development plan. The size of the living space of the selected neighborhoods is successively used as a design parameter to support the computer-assisted generation of several design proposals. Each proposal can be exported, shared, and visualized online. As a test case, a to-be-planned neighborhood in Amsterdam, called “Sloterdijk One”, has been chosen.
