Morphological shape design is interpreted in this paper as a search for new shapes from a particular application domain represented by a set of selected shape instances. This paper proposes a new foundation for morphological shape design and generation. In contrast to existing generative procedures, an approach based on a user-controlled metamorphosis between functionally based shape models is presented. A formulation of the pairwise metamorphosis is proposed with a variety of functions described for the stages of deformation, morphing and offsetting. This formulation is then extended to the metamorphosis between groups of shapes with user-defined, dynamically correlated and weighted feature elements. A practical system was implemented in the form of plugin to Maya and tested by an industrial designer on a group of representative shapes from a particular domain. © 2013 Elsevier Ltd.

The automatic generation of volumes bounding the intersection of two implicit surfaces (isosurfaces of real functions of 3D point coordinates) or feature based volumes (FBV) is presented. Such FBVs are defined by constructive operations, function normalization and offsetting. By applying various offset operations to the intersection of two surfaces, we can obtain variations in the shape of an FBV. The resulting volume can be used as a boundary for blending operations applied to two corresponding volumes, and also for visualization of feature curves and modeling of surface based structures including microstructures. © 2011 Elsevier Ltd.

A well-known definition of the visualization is a mapping of initial data to a representation, which can be perceived by humans. The addressed human senses include not only vision, but hearing, sense of touch, smell and others including combinations of them. Formulation of a formalized approach to such a mapping of data to various human sensor signals (sensory stimuli) is an open research topic. We discuss here scientific visualization as a method of data analysis extended by data sonification, which provides mapping of data to sounds. A formalization of the correspondence between the initial data and sensory stimuli is proposed. We propose an approach to mapping data via multidimensional geometric models onto multimedia objects described in multimedia coordinates, and illustrate our approach with a case study of analysis of a scalar field using both visual and auditory data representations.

Graphical Models | Year: 2011

We propose a new approach to modelling heterogeneous objects containing internal volumetric structures with size of details orders of magnitude smaller than the overall size of the object. The proposed function-based procedural representation provides compact, precise, and arbitrarily parametrized models of coherent microstructures, which can undergo blending, deformations, and other geometric operations, and can be directly rendered and fabricated without generating any auxiliary representations (such as polygonal meshes and voxel arrays). In particular, modelling of regular lattices and cellular microstructures as well as irregular porous media is discussed and illustrated. We also present a method to estimate parameters of the given model by fitting it to microstructure data obtained with magnetic resonance imaging and other measurements of natural and artificial objects. Examples of rendering and digital fabrication of microstructure models are presented. © 2011 Elsevier Inc. All rights reserved.

Three-dimensional (3D) printing has the potential to transform science and technology by creating bespoke, low-cost appliances that previously required dedicated facilities to make. An attractive, but unexplored, application is to use a 3D printer to initiate chemical reactions by printing the reagents directly into a 3D reactionware matrix, and so put reactionware design, construction and operation under digital control. Here, using a low-cost 3D printer and open-source design software we produced reactionware for organic and inorganic synthesis, which included printed-in catalysts and other architectures with printed-in components for electrochemical and spectroscopic analysis. This enabled reactions to be monitored in situ so that different reactionware architectures could be screened for their efficacy for a given process, with a digital feedback mechanism for device optimization. Furthermore, solely by modifying reactionware architecture, reaction outcomes can be altered. Taken together, this approach constitutes a relatively cheap, automated and reconfigurable chemical discovery platform that makes techniques from chemical engineering accessible to typical synthetic laboratories. © 2012 Macmillan Publishers Limited.

Existing mesh and voxel based modeling methods encounter difficulties when dealing with objects containing cellular structures on several scale levels and varying their parameters in space. We describe an alternative approach based on using real functions evaluated procedurally at any given point. This allows for modeling fully parameterized, nested and multi-scale cellular structures with dynamic variations in geometric and cellular properties. The geometry of a base unit cell is defined using Function Representation (FRep) based primitives and operations. The unit cell is then replicated in space using periodic space mappings such as sawtooth and triangle waves. While being replicated, the unit cell can vary its geometry and topology due to the use of dynamic parameterization. We illustrate this approach by several examples of microstructure generation within a given volume or along a given surface. We also outline some methods for direct rendering and fabrication not involving auxiliary mesh and voxel representations. © 2011 Elsevier Ltd. All rights reserved.

Scientific Visualization | Year: 2013

A general definition of visualization is a mapping of data to a representation that can be perceived. Types of this representation can be not only visual, but auditory, tactile, and others directly related to human senses or combinations of them. A formal framework for mapping data to various sensory stimuli is an open research issue. In this paper, we discuss extended scientific visualization as a method of data analysis. A formalization of establishing correspondences between the initial data and multiple human perception inputs is proposed. We introduce an approach to mapping data through multidimensional geometric models onto multimedia objects based on multimedia coordinates, and illustrate this approach with a case study of scalar fields analysis involving both visual and auditory representations.

Rising Media announced the full program for the Inside 3D Printing San Diego event, taking place at the San Diego Convention Center on December 14-15, 2016. Inside 3D Printing is the largest professional 3D printing event worldwide, having hosted 33 events globally since its launch in 2013. This will be the series’ fourth edition in California, with previous events hosted in San Jose and Santa Clara. The Inside 3D Printing San Diego program, which is chaired by Tyler Benster, General Partner, Asimov Ventures, features dedicated conference tracks focused on 3D printing applications in business, manufacturing, medical, and metal; keynote speeches from industry leaders Weidong Huang of Northwestern Polytechnical University, Hod Lipson of Columbia University, and Terry Wohlers of Wohlers Associates, Inc.; a full day of pre-conference workshops on December 13; as well as networking opportunities for additive manufacturing professionals to forge valuable industry connections. “3D printing is undergoing a watershed moment, as big and small companies alike begin to use the technology to manufacture finished goods. Several breakthrough technologies in plastics and metals promise to drive this exponential growth,” said Tyler Benster, conference chair and General Partner, Asimov Ventures. He continued, “We have some surprises in store at Inside 3D Printing San Diego, as several companies emerge from stealth mode to unveil ground-breaking new technology, while other established presenters discuss best practices for emerging business models.” Rising Media also announced The Nature Game, a competition challenging participants to create objects, which are hard or impossible to determine as objects having been created by natural growth or by human 3D design and manufacturing. Inspired by Alan Turing's 1950 Turing Test and developed by Uformia's Turlif Vilbrandt, The Nature Game asks the question, "Can an object be explicitly designed and fabricated by humans that seems to be naturally grown and/or expresses properties and complexity only found in naturally produced objects?" Objects created for The Nature Game will be on display at Inside 3D Printing San Diego where event attendees will have the opportunity to view the objects and guess whether they are human or nature made. "We are now able to understand and control all types of matter at scales beyond our own perception. In the next 30 years, manufacturing systems will communicate and fabricate alongside natural systems and human made objects will no longer stand apart and separated from natural processes,” said Turlif Vilbrandt, CTO, Uformia. San Diego-based bioprinting company Organovo is confirmed to participate and display 3D printed tissue for attendees to view through a microscope at Inside 3D Printing San Diego as part of The Nature Game. For more information, including submission guidelines and deadlines, visit TheNatureGame.org. Also on the program will be the Frontier Tech Showdown, a startup competition for early-stage startups in 3D printing, robotics, and virtual and augmented reality; the Frontier Tech Hackathon hosted by Amazon Alexa; and a special panel aimed at exploring diversity and multiculturalism in frontier technology industries. Inside 3D Printing San Diego is co-located with Rising Media's RoboUniverse and Virtual Reality Summit as the first Frontier Tech Forum.
