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.

Between the end of the twenties and the beginning of the World war two Turin, as the most of the Italian cities, was endowed by the fascist regime of many new buildings to guarantee its visibility and to control the territory: the fascist party main houses and the local ones. <br><br> The style that was adopted for these constructions was inspired by the guide lines of the Modern movement which were spreading by a generation of architects as Le Corbusier, Gropius, Mendelsohn. <br><br> At the end of the war many buildings were reconverted to several functions that led heavy transformations not respectful of the original worth, other were demolished. <br><br> Today it's possible to rebuild those lost architectures in their primal format as it was created by their architects on paper (and in their mind). This process can guarantee the three-dimensional perception, the authenticity of the materials and the placement into the Turin urban tissue, using static and dynamic digital representation systems. The “three-dimensional re-drawing” of the projects, thought as an heuristic practice devoted to reveal the original idea of the project, inserts itself in a digital model of the urban and natural context as we can live it today, to simulate the perceptive effects that the building could stir up today. The modeling skills are the basis to product videos able to explore the relationship between the environment and “re-built architectures”, describing with the synthetic movie techniques, the main formal and perceptive roots. The model represents a scientific product that can be involved in a virtual archive of cultural goods to preserve the collective memory of the architectural and urban past image of Turin.

Contemporary technological development (CAD/CAM/CAE, VR, AR, MR) made conventional methods of Descriptive and Constructive Geometry uncompleted. Application and use of new technologies in Constructive geometry requires educational process with the aim to have complete knowledge of all fields that belong to this area. The aspect and results research shows that knowledge acquired in this way by using new technology, develops students' skills that are very important in senior years of studies, particularly in the field of engineering design. Interactive dynamic 3D geometry could not be achieved by conventional ways of studying. The use of modern technology should enable expanding the fields of research as well as preservation of the theoretical knowledge of descriptive geometry.

In this chapter are developed some considerations about the heuristic potentialities of parametric digital modeling as a tool for analyzing and interpreting architectural heritage. Observed that the parametric thinking in architecture could be recognized almost from the origin, new parametric modeling software allows to verify the design criteria of the past. On the basis of previous studies on Baroque vaulted atria, this chapter develops, using parametric modeling tools, a real vocabulary of shapes and their possible combinations, suggested by the architectural literature of the time and the survey of about seventy atria in Turin. This method has been tested on the case study of the lunettes dome in the atrium of Palazzo Carignano.

Small Building

Architecture, engineering, and construction industries maintain a long standing desire to enhance design communication through various forms of 3D CAD modeling. In spite the introduction of Building Information Modeling (BIM), designers and builders expect varying amounts of communication loss once construction has started due to indirect construction techniques or hand based methods to manufacture buildings. This is especially true for houses and small structures, buildings that makeup the core of villages and suburbs. Unfortunately, paper documentation and reading 3D CAD models on screen continue the trend of indirect production defined in most manufacturing industries as error. The emerging application of CAD/CAM within design and construction industries provides hope for elevated communication between design and building. With CAD/CAM, it is possible to manufacture buildings of all types and sizes directly from CAD files similar to mass produced artifacts, thus reducing complexity in communication between parties. This chapter is presentation of one process of direct manufacturing from CAD and the emerging possibilities for small building production using digital fabrication. The chapter will focus on houses to illustrate the potential of direct manufacturing of buildings from CAD data.
