    L'obiettivo di questa tesi è sviluppare strumenti utili per creare opere d'arte decorative digitali in 3D. Uno dei processi decorativi piÚ comunemente usati prevede la creazione di pattern decorativi, al fine di abbellire gli oggetti. Questi pattern possono essere dipinti sull'oggetto di base o realizzati con l'applicazione di piccoli elementi decorativi. Tuttavia, la loro realizzazione nei media digitali non è banale. Da un lato, gli utenti esperti possono eseguire manualmente la pittura delle texture o scolpire ogni decorazione, ma questo processo può richiedere ore per produrre un singolo pezzo e deve essere ripetuto da zero per ogni modello da decorare. D'altra parte, gli approcci automatici allo stato dell'arte si basano sull'approssimazione di questi processi con texturing basato su esempi o texturing procedurale, o con sistemi di riproiezione 3D. Tuttavia, questi approcci possono introdurre importanti limiti nei modelli utilizzabili e nella qualità dei risultati. Il nostro lavoro sfrutta invece i recenti progressi e miglioramenti delle prestazioni nel campo dell'elaborazione geometrica per creare modelli decorativi direttamente sulle superfici. Presentiamo una pipeline per i pattern 2D e una per quelli 3D, e dimostriamo come ognuna di esse possa ricreare una vasta gamma di risultati con minime modifiche dei parametri. Inoltre, studiamo la possibilità di creare modelli decorativi tangibili. I pattern 3D generati possono essere stampati in 3D e applicati a oggetti realmente esistenti precedentemente scansionati. Discutiamo anche la creazione di modelli con mattoncini da costruzione, e la possibilità di mescolare mattoncini standard e mattoncini custom stampati in 3D. Ciò consente una rappresentazione precisa indipendentemente da quanto la voxelizzazione sia approssimativa. I principali contributi di questa tesi sono l'implementazione di due diverse pipeline decorative, un approccio euristico alla costruzione con mattoncini e un dataset per testare quest'ultimo.The aim of this thesis is to develop effective tools to create digital decorative 3D artworks. Real-world art often involves the use of decorative patterns to enrich objects. These patterns can be painted on the base or might be realized with the application of small decorative elements. However, their creation in digital media is not trivial. On the one hand, users can manually perform texture paint or sculpt each decoration, in a process that can take hours to produce a single piece and needs to be repeated from the ground up for every model that needs to be decorated. On the other hand, automatic approaches in state of the art rely on approximating these processes with procedural or by-example texturing or with 3D reprojection. However, these approaches can introduce significant limitations in the models that can be used and in the quality of the results. Instead, our work exploits the recent advances and performance improvements in the geometry processing field to create decorative patterns directly on surfaces. We present a pipeline for 2D and one for 3D patterns and demonstrate how each of them can recreate a variety of results with minimal tweaking of the parameters. Furthermore, we investigate the possibility of creating decorative tangible models. The 3D patterns we generate can be 3D printed and applied to previously scanned real-world objects. We also discuss the creation of models with standard building bricks and the possibility of mixing standard and custom 3D-printed bricks. This allows for a precise representation regardless of the coarseness of the voxelization. The main contributions of this thesis are the implementation of two different decorative pipelines, a heuristic approach to brick construction, and a dataset to test the latter

    The study of the textile sector has always been central to economic history: from reconstructions of the dynamic growth in the medieval wool industry, to the rise of silk and light and mixed fabrics in the modern era, to the driving role of cotton in the industrialisation process. Although the dynamics of textile manufacturing are closely linked to the transformations of fashion, economic history has long neglected its role as a factor in economic change, treating it primarily as a kind of exogenous catalyst. This book makes a decisive contribution to the understanding of a fundamental transformation, the consequences of which are projected into contemporary society, but which matured in pre-industrial times: the advent of fashion

    PAVEL: Decorative Patterns with Packed Volumetric Elements

    Full text link
    Many real-world hand-crafted objects are decorated with elements that are packed onto the object's surface and deformed to cover it as much as possible. Examples are artisanal ceramics and metal jewelry. Inspired by these objects, we present a method to enrich surfaces with packed volumetric decorations. Our algorithm works by first determining the locations in which to add the decorative elements and then removing the non-physical overlap between them while preserving the decoration volume. For the placement, we support several strategies depending on the desired overall motif. To remove the overlap, we use an approach based on implicit deformable models creating the qualitative effect of plastic warping while avoiding expensive and hard-to-control physical simulations. Our decorative elements can be used to enhance virtual surfaces, as well as 3D-printed pieces, by assembling the decorations onto real-surfaces to obtain tangible reproductions.Comment: 11 page

    Expanding Fields of Architectural Discourse and Practice: Curated Works from the P.E.A.R. Journal.

    Get PDF
    Expanding Fields of Architectural Discourse and Practice presents a selection of essays, architectural experiments and works that explore the diversity within the fields of contemporary architectural practice and discourse. Specific in this selection is the question of how and why architecture can and should manifest in a critical and reflective capacity, as well as to examine how the discipline currently resonates with contemporary art practice. It does so by reflecting on the first 10 years of the architectural journal, P.E.A.R. (2009 to 2019). The volume argues that the initial aims of the journal – to explore and celebrate the myriad forms through which architecture can exist – are now more relevant than ever to contemporary architectural discourse and practice

    Moschatel Press: Craft, Concrete, and Constructivism in the Cotswolds

    Get PDF
    In 1973 in the Gloucestershire town of Nailsworth, the poet Thomas A. Clark and the artist Laurie Clark established their own small publishing imprint, Moschatel Press. Despite early titles by, among others, Ian Hamilton Finlay and Cid Corman, Moschatel Press has, primarily, published the Clarks’ own work, much of which is collaborative. Utilizing simple formats such as postcards, folding cards, pamphlets, and chapbooks, Moschatel Press publications have explored the indivisible relationship that exists between the printed format—its design and construction—and the expressive and material conditions of text and image. It is perhaps not surprising therefore that the press has been frequently associated with concrete and post-concrete poetry. However, prompted by the press’s Cotswolds provenance, this article extends this perspective by examining the ways in which the Arts and Crafts Movement’s close associations with the Cotswolds have shaped the Clarks’ publishing practices and poetics. In particular, this article considers how the Clarks’ early Moschatel Press publications have evoked the Arts and Crafts Movement’s commitment to honest design, formal simplicity, and purity. It also addresses how the Clarks have synthesized and confused these key principles of the Arts and Crafts Movement with notions of making, construction, and sincerity that inform avant-garde notions of “constructivism” in literature and visual art. In doing so, this article claims that the Clarks’ Moschatel Press encourages new ways of thinking about these seemingly antithetical milieus and their relevance in a long and enduring tradition of independent publishing in which Moschatel Press itself remains a formative model and inspirational touchstone
