S3PM Symposia

Two consecutive co-located symposia

Solid and Physical Modeling (SPM-2017)

Symposium: June 19th to 21st, 2017

The ACM Symposium on "Solid Modeling and Applications (SMA)," SPM has been the primary venue for disseminating research results in the design, representation, analysis, visualization, and use of digital models of real or planned solid objects and of their bounding surfaces. Its initial focus was on the theoretical and algorithmic tools that produce and exploit unambiguous representations of the geometry of such objects. Its broadening to "Solid and Physical Modeling (SPM)" extended the focus from solids to also include models of their internal structures, physical properties, and behaviors.

Deadlines: February 18th (abstract), March 3rd (full papers), 2017

S3PM :: Replicability Stamp:

S3PM participates in the Replicability Stamp Initiative, an additional recognition for authors who are willing to go one step further, and in addition to publishing the paper, provide a complete open-source implementation. The Graphics Replicability Stamp Initiative (GRSI) is an independent group of volunteers who want to help the community by enabling sharing of code and data as a community resource for non-commercial use. The volunteers review the submitted code and certify its replicability, awarding a replicability stamp, which is an additional recognition for authors of accepted papers who are willing to provide a complete implementation of their algorithm, to replicate the results presented in their paper. The replicability stamp is not meant to be a measure of the scientific quality of the paper or of the usefulness of presented algorithms. Rather, it is meant to be an endorsement of the replicability of the results presented in it!

The paper and the recognition of the service provided to the community by releasing the code. Submissions for the replicability stamp will be considered only after the paper has been fully accepted. Submissions that are awarded the replicability stamp will receive additional exposure by being listed on this website. The purpose of this stamp is to promote reproducibility of research results and to allow scientists and practitioners to immediately benefit from state-of-the-art research results, without spending months re-implementing the proposed algorithms and trying to find the right parameter values. We also hope that it will indirectly foster scientific progress, since it will allow researchers to reliably compare with and to build upon existing techniques, knowing that they are using exactly the same implementation. This is an initiative supported by a growing list of publishers, journals, and conferences.

The submission procedure is lightweight (click here to see requirements) and we encourage the authors of accepted papers to participate by filling the form that they received in the acceptance letter. The papers with the replicability stamp will receive additional exposure during S3PM, and will be listed on the replicability stamp website.

The deadline for applying is May 26th, 2017 at 23:59 CET. For any request or comment regarding the replicability stamp, please contact directly the paper chairs of the corresponding conference.

The qualified papers will be decorated with location:middle in the program (logo designed by Michela Mortara).

Bézier Award 2017 :: Call for Nominations:

Sponsored by the Solid Modeling Association (SMA) and the Symposium on Solid and Physical Modeling (SPM).

With the approval of the family of the late Pierre Bézier, the Solid Modeling Association established in 2007 the Pierre Bézier Award for contributions in Solid, Geometric and Physical Modeling and for their Applications. Pierre Bézier was one of the founders of these fields. Beginning with his work on representing curves, and continuing through his work on one of the first CAD/CAM systems at Renault (UNISURF), Pierre Bézier led the transformation of design and manufacturing, through mathematics and computing tools, into computer aided design and three dimensional modeling. He made contributions to computer control, interactive free-form curve and surface design and 3D milling for manufacturing clay models and masters. Bézier's approach to research exemplifies how the problems from the real world can drive scientific inquiry and lead to engineering accomplishments.

Solid, geometric and physical modeling have matured and have come a long way since the 1950s, resulting in a rich set of theories, mathematics and algorithms that define and manipulate representations of physical objects, their properties, and their associated abstractions. These representations are intimately tied to processes (such as simulation, design, manufacturing, and analysis) and application domains (automotive, aerospace, bio-medical, graphic arts, etc). These representations support the creation, exchange, simulation, visualization, animation, interrogation, and annotation of the digital models of the objects and their evolution.

The Pierre Bézier Award and the acceptance lecture will be presented at the SPM-2017 Symposium on June 21st, 2017.

Keynote Speakers

World-renowned scientists and engineers

Digital Human Teleportation using Deep Learning

Time and Location: Thursday (June 22nd) 14:00 - 15:00, Banatao Auditorium

The age of immersive technologies will create a growing need for processing detailed visual representations of ourselves as virtual reality (VR) is growing into the next generation platform for online communication. A realistic simulation of our presence in such virtual world is unthinkable without a compelling and directable 3D digitization of ourselves. With the wide availability of mobile cameras and the emergence of low-cost VR head mounted displays (HMD), my research goal is to build a comprehensive and deployable teleportation framework for realistic 3D face-to-face communication in cyberspace. By pushing the boundaries in data-driven human digitization as well as bridging concepts in computer graphics and deep learning research, I will showcase several highlights of our current research, from photorealistic avatar creation from a single image, facial performance-sensing head mounted displays, and full-body dynamic shape capture. I will also introduce new deep learning tools for processing clothed 3D human bodies, inferring photorealistic 3D faces from unconstrained low resolution images, as well as demonstrate the latest highlights from Pinscreen.

Driving 3D and 4D Printing Forward with Computational Design

Time and Location: Tuesday (June 20th) 14:00 - 15:00, Banatao Auditorium

The recent rise in digital fabrication, including 3D and 4D printing, may be the best thing that has ever happened to the area of computational design. For years we have been developing algorithms and methods for automatically generating and optimizing designs from large, complex solution spaces. Today, designers struggle with just this, to design parts that take full advantage of the complex shapes and material combinations that are now possible with 3D printing. 4D printing extends on this to enable designs to reconfigure themselves in time after printing. This is a new and exciting playground for computational design. Highlights of our research on novel methods for automatically generating, simulating, and optimizing structural and mechanical systems that can be directly fabricated with 3D printing are presented. The focus is on a multi-material polymer-based process that has also enabled the development of tunable, multi-stable, reconfigurable 4D printed structures.

Restricted Constrained Delaunay Triangulations

Time and Location: Friday (June 23rd) 14:00 - 15:00, Banatao Auditorium

Surface meshes are used extensively in computer graphics, boundary element methods, and many other applications. Researchers have sought surface triangulations that have formal mathematical properties similar to those enjoyed by Delaunay triangulations in the plane. They succeeded by inventing the "restricted Delaunay triangulation," which is a subcomplex of the three-dimensional Delaunay triangulation. In other words, given a smooth surface embedded in three-dimensional space, we compute a set of points lying on the surface, we compute the 3D Delaunay triangulation of those points, and we select a subset of its triangles to serve as a triangulation of the surface. This subset of triangles, the restricted Delaunay triangulation, has proven itself as a mathematically powerful tool for surface meshing and surface reconstruction.
I address a question of Bruno Levy: can we constrain restricted Delaunay triangulations to include specified edges? That is, can we define a mathematically well-behaved, Delaunay-like, edge-constrained triangulation on a smooth surface? We do so by defining a specialized Voronoi diagram on the surface, then dualizing it to obtain a triangulation. But to force specified edges to appear in this triangulation, we must perform topological surgery on the surface...and that's where things get weird and interesting.
(This work is done jointly with Marc Khoury and Marc van Kreveld.)

Computation of Frame Fields Using Ginzburg-Landau Functional: Application to Quad and Hex Meshing

Time and Location: Monday (June 19th) 14:00 - 15:00, Banatao Auditorium

This presentation essentially deals with indirect (quad-) hex-dominant. Several topics will be covered:
  • Frame fields are an essential tool for constructing such meshes. We propose here a formulation that is based on Gizburg-Landau functional.
  • Hex-dominant meshing relies on the detection of adjacent tetrahedra that may be combined to form hexahedra. In this presentation, we introduce a new algorithm that performs this identification and build the largest set of potential hexes from an input tetrahedral mesh.
  • Parallelization of the whole mesh generation process on a Knigh’s Landing architecture is also presented.
