Physical Visualization of Geospatial Datasets
TLDR
This proposed approach includes a mechanism for attaching a set of 3D printed segments to produce a scalable model of the Earth to be used for visualizing multiresolution geospatial datasets.Abstract:
Geospatial datasets are too complex to easily visualize and understand on a computer screen. Combining digital fabrication with a discrete global grid system (DGGS) can produce physical models of the Earth for visualizing multiresolution geospatial datasets. This proposed approach includes a mechanism for attaching a set of 3D printed segments to produce a scalable model of the Earth. The authors have produced two models that support the attachment of different datasets both in 2D and 3D format.read more

Artifact-Based Rendering: Harnessing Natural and Traditional Visual Media for More Expressive and Engaging 3D Visualizations
Seth Johnson,Francesca Samsel,Gregory Abram,Daniel W. Olson,Andrew J. Solis,Bridger Herman,Phillip J. Wolfram,Christophe Lenglet,Daniel F. Keefe +8 more
TL;DR: Artifact-Based Rendering (ABR) as discussed by the authors is a framework of tools, algorithms, and processes that makes it possible to produce real, data-driven 3D scientific visualizations with a visual language derived entirely from colors, lines, textures, and forms created using traditional physical media or found in nature.

Physicalizing cardiac blood flow data via 3D printing
TL;DR: A novel slice-based physical model is proposed as a complementary method for visualizing blood flow data and it is demonstrated that the technique is capable of transforming volumetric flow data into a tangible, easily fabricable model.

TL;DR: The authors developed a corpus of example data physicalizations from research literature and physicalization practice and unpacked the "rendering" phase of the extended InfoVis pipeline in greater detail through these examples, with the aim of identifying ways that researchers, artists, and industry practitioners "render" physicalizations using digital design and fabrication tools.

Landscaper: A Modeling System for 3D Printing Scale Models of Landscapes
TL;DR: This system retrieves GIS relevant to creating a physical model of a geospatial region and then addresses the two major limitations of affordable 3D printers, namely the limited number of materials and available printing volume.

Data in Context: Engaging Audiences with 3D Physical Geo-Visualization
TL;DR: This paper sets out to compare the effectiveness and user engagement of geo-visualizations data projected on either a flat 2D surface or a 3D representation of the terrain, and proposes that physical geo- visualization is a thriving field for further research.

Digital Fabrication and Making' in Education: The Democratization of Invention
TL;DR: The Treviso Arithmetic, from 1478, teaches students how to do multiplication and division using "exactly" the same paper-based algorithms we use today as mentioned in this paper, and their descriptions of 16th century schools and their curricula look strikingly similar to today's mathematics classes.

Geodesic Discrete Global Grid Systems
TL;DR: Geodesic Discrete Global Grid Systems as discussed by the authors can be constructed by specifying five substantially independent design choices: a base regular polyhedron, a fixed orientation of the base regular polygons relative to the Earth, a hierarchical spatial partitioning method defined symmetrically on a face (or set of faces), a method for transforming that planar partition to the corresponding spherical/ellipsoidal surface, and a method of assigning point representations to grid cells.

Parameterization of Faceted Surfaces for Meshing using Angle-Based Flattening
Alla Sheffer,E. de Sturler +1 more
TL;DR: A new method to compute planar triangulations of faceted surfaces for surface parameterization that defines the flattening problem as a constrained optimization problem in terms of angles (only), which makes the method more stable and robust than previous approaches, which used node locations in their formulations.

Chopper: partitioning models into 3D-printable parts
TL;DR: Chopper as discussed by the authors decomposes a large 3D object into smaller parts so that each part fits into the 3D printing volume, and these parts can then be assembled to form the original object.
