PAVEL: Decorative Patterns with Packed Volumetric Elements
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
State of the Art on Stylized Fabrication
© 2018 The Authors Computer Graphics Forum © 2018 The Eurographics Association and John Wiley & Sons Ltd. Digital fabrication devices are powerful tools for creating tangible reproductions of 3D digital models. Most available printing technologies aim at producing an accurate copy of a tridimensional shape. However, fabrication technologies can also be used to create a stylistic representation of a digital shape. We refer to this class of methods as ‘stylized fabrication methods’. These methods abstract geometric and physical features of a given shape to create an unconventional representation, to produce an optical illusion or to devise a particular interaction with the fabricated model. In this state-of-the-art report, we classify and overview this broad and emerging class of approaches and also propose possible directions for future research
Toward Shape Optimization of Soft Robots
International audienceIn this paper we present our work on shape optimization for soft robotics where the shape is optimized for a given soft robot usage. To obtain a parametric optimization with a reduced number of parameters, we rely on an approach where the designer progressively refines the parameter space and the fitness function until a satisfactory design is obtained. In our approach, we automatically generate FEM simulations of the soft robot and its environment to evaluate a fitness function while checking the consistency of the solution. Finally, we have coupled our framework to an evolutionary optimization algorithm, and demonstrated its use for optimizing the design of a deformable leg of a locomotive robot
Tile-based Pattern Design with Topology Control
International audiencePatterns with desired aesthetic appearances and physical structures are ubiquitous.However, such patterns are challenging to produce - manual authoring requires significant expertise and efforts while automatic computation lacks sufficient flexibility and user control.We propose a method that automatically synthesizes vector patterns with visual appearance and topological structures designated by users via input exemplars and output conditions.The input can be an existing vector graphics design or a new one manually drawn by the user through our interactive interface.Our system decomposes the input pattern into constituent components (tiles) and overall arrangement (tiling).The tile sets are general and flexible enough to represent a variety of patterns, and can produce different outputs with user specified conditions such as size, shape, and topological properties for physical manufacturing
Design Transactions
Design Transactions presents the outcome of new research to emerge from ‘Innochain’, a consortium of six leading European architectural and engineering-focused institutions and their industry partners. The book presents new advances in digital design tooling that challenge established building cultures and systems. It offers new sustainable and materially smart design solutions with a strong focus on changing the way the industry thinks, designs, and builds our physical environment.
Divided into sections exploring communication, simulation and materialisation, Design Transactions explores digital and physical prototyping and testing that challenges the traditional linear construction methods of incremental refinement. This novel research investigates ‘the digital chain’ between phases as an opportunity for extended interdisciplinary design collaboration. The highly illustrated book features work from 15 early-stage researchers alongside chapters from world-leading industry collaborators and academics
