“…What RE can add to this meticulous archival study is the ability to activate the archive contents to produce new knowledge or share it with different actors. For example, knowing how an item was historically crafted allows an understanding of materials, techniques and technologies employed, the problems related to conservation and restoration, and the shortcomings in the documentation (Fondevilla, 2019).…”

Currently, the issue of archival fashion is mainly to explore emergent methods and digital technologies' application to foster innovation in terms of activation, knowledge-sharing and knowledge-generation related to archival artefacts. The complex archival collections consist of a plurality of artefacts, meanings, and practices interconnected through technologies that make the archive a knowledge-generating process.Narrowing the study on fashion archives, these are characterised by a significant heterogeneity of materials preserved by companies, private collectors and cultural institutions as evidence of heritage values, design activities, manufacturing culture, and creative processes embedded in artefacts and intangible know-how.This inner knowledge inherently linked to archival fashion stays permanently implicit in the artefact and usually cannot be accessed by public audiences. Even though Cultural Institutions currently deploy technologies to democratise three-dimensional garment explorations, there are still rare attempts that operate with digital technologies to allow an in-depth study of the creative process and technical know-how lying behind fashion heritage.In light of this, the paper explores the Reverse Engineering (RE) methods applied to fashion archives to access and unlock the implicit features and techniques embedded in archival fashion to facilitate knowledge-sharing and knowledge-generation processes in exploring culture-intensive artefacts through digital technology application.Through the explorations of case studies in the fashion archival context, the paper will focus on augmented fruition practices to derive knowledge from the reading of the archive itself, starting with RE and reflecting on virtual and augmented integration to represent and disseminate fashion culture with the final aim of activating the vast inner fashion knowledge patrimony.Specific considerations will regard the potentialities of digital integration in fashion archives in terms of (1) the different nature of the knowledge unfolded through RE depending on peculiar aspects of archival artefacts; (2) technologies used to encode/decode inner knowledge; (3) the future digital directions related to archival practices and experiences derived from them, also in light of the changes in design languages when technological approaches hybridise those of humans.

“…Among systems based on priors, some rely on hypotheses on the nature of the input sketch, eg. the use of design sketches [6] or sketches depicting curvature lines [7] while other methods focus on hypotheses on the 3D surface to be created, such as in the case of developable products [8,9,10].…”

In this digital age, architects still need to alternate between paper sketches and 3D modeling software for their designs. Indeed, while 3D models enable to explore different views, creating them at very early stages might reduce creativity since they do not allow to superpose several tentative designs nor to refine them progressively, as sketches do. To enable exploratory design in 3D, we introduce Nested Explorative Maps, a new system dedicated to interactive design in architecture. Our model enables coarse to fine sketching of nested architectural structures, enabling to progressively sketch a 3D building from floor plan to interior design, thanks to a series of nested maps able to spread in 3D. Each map allows the visual representation of uncertainty as well as the interactive exploration of the alternative, tentative options. We validate the model through a user study conducted with professional architects, enabling us to highlight the potential of Nested Explorative Maps for conceptual design in architecture.

“…This is typically achieved by segmenting or cutting the shape into parts with low Gaussian curvature and parameterizing each part onto the plane. Alternatively, the shape can be a priori modeled or approximated as a piecewise developable surface, which is a current topic of active research [Chandra et al 2015;Fondevilla et al 2017;Jung et al 2015;Kilian et al 2008;Kolmianič and Guid 2002;Liu et al 2009;Rose et al 2007;Tang et al 2016;Zeng et al 2012]. The assembly by gluing or sewing the pieces together requires precision and carefully following the instructions.…”

3D model single spiraling curve segmentation developable shape zippable bunny Fig. 1. The pipeline of our approach. Starting from a 3D model, the user decomposes the shape into topological cylinders. Our algorithm automatically produces a single continuous curve on the shape that spirals along the cylinders. It proceeds to cut the shape along the curve and creates a developable surface that can be trivially unfolded into a single 2D shape -the so called zippable. Based on the flattening, plans for laser cutting it from fabric are generated. Finally, we attach a zipper with a single slider to the boundary of the zippable. Zipping it up reproduces a faithful approximation of the input model.Fabrication from developable parts is the basis for arts such as papercraft and needlework, as well as modern architecture and CAD in general, and it has inspired much research. We observe that the assembly of complex 3D shapes created by existing methods often requires first fabricating many small parts and then carefully following instructions to assemble them together. Despite its significance, this error prone and tedious process is generally neglected in the discussion. We present the concept of zippablessingle, two dimensional, branching, ribbon-like pieces of fabric that can be quickly zipped up without any instructions to form 3D objects. Our inspiration comes from the socalled zipit bags [zipit 2017], which are made of a single, long ribbon with a zipper around its boundary. In order to "assemble" the bag, one simply needs to zip up the ribbon. Our method operates in the same fashion, but it can be used to approximate a wide variety of shapes. Given a 3D model, our algorithm produces plans for a single 2D shape that can be laser cut in few parts from fabric or paper. A zipper can then be attached along the boundary by sewing, or by gluing using a custom-built fastening rig. We show physical and virtual results that demonstrate the capabilities of our method and the ease with which shapes can be assembled.
