Workshop: The History of Implicit Surfaces

Shape Modeling International (SMI 2022) will have a workshop/panel that is called "The History of Implicit Surfaces". The goal is not only to discuss important milestones but also to introduce the human element behind the discoveries. Participants will tell us anecdotes providing insights behind the discoveries. We hope that a science historian or a popular science writer (or a few of speakers) can turn the collected information first into an article and later into a book.

The workshop is free to public. Please check the Registration page for registeration.

Replicability Stamp

SMI 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 SMI, and will be listed on the replicability stamp website.

The qualified papers will be decorated with the logo in the program.

Keynotes

Title:Material-driven Realization of 3D Surfaces

Date

Abstract: Many applications of geometry processing involve realizing, or fabricating, a 3D model designed using a modeling software. While the realization mechanisms are quite varied, many of the underlying mathematical constraints that allow a seamless transition from modeling to the realization of 3D models are similar across domains. Often, these mechanisms involve meshing, where an idealized smooth surface is sampled using discrete building blocks, such as planar panels, thin wires, or yarn stitches. In this talk we will survey the challenges of mesh realization using different materials, present solutions using discrete tangent vector fields, and demonstrate them in different applications.

The Structural Geometry of 3D Concrete Printing

Date:

Abstract: This keynote, motivated by the rapid growth in large-scale 3D concrete printing (3DCP), addresses the current lack of both computational design tools and integrated design-to-production (DTP) solutions for this fabrication technology. It is guided by a novel insight regarding the applicability of design and analysis methods developed for unreinforced masonry to large-scale, layered 3D printing with materials favouring compression such as concrete. As an example, the lecture will present the custom toolchain that enabled the integration of shape-design, structural engineering, and robotic concrete printing for the design, production, and construction of Striatus, a discrete, dry-assembled, fully unreinforced masonry foot bridge.

Creative AI : Turning 3D virtual worlds into interactive scientific test-beds

Date:

Abstract: Visual representations are essential in science, as they facilitate intuition and ease communication. While the 2D sketches used for centuries recently evolved into 3D contents, the latter are generally not responsive: they do not allow scientists to interact with their models, change hypotheses on the fly and experiment their effects. In this talk, we explore the use of smart 3D environments as visual testbeds in science. We show that a combination of efficient procedural models expressing knowledge, expressive sculpting or sketching interfaces, and learning mechanisms, can help to reach this goal. We illustrate this through a variety of examples, from sculpting eroding mountains that express geological knowledge to helping prehistorians explore past ecosystems with flora and animated fauna.

Robust Black-Box Analysis

Date:

Abstract: The finite element method (FEM) is the most commonly used discretization of PDEs due to its generality and rich selection of off-the-shelf commercial implementations. Ideally, a PDE solver should be a "black-box": the user provides as input the domain's boundary, the boundary conditions, and the governing equations, and the code returns an evaluator that can compute the value of the solution at any point of the input domain. This is surprisingly far from being the case for all existing open-source or commercial software, despite the many research efforts in this direction and the sustained interest from academia and industry. To a large extent, this issues from treating meshing (and geometry more in general) and FEM basis construction as two disjoint problems. The FEM basis construction may make a seemingly innocuous assumption (e.g., on the geometry of elements), leading to exceedingly difficult requirements for meshing software. This state of matters presents a fundamental problem for all applications, and is even more problematic in applications that require fully automatic, robust processing of large collections of meshes. We present recent advancements towards an integrated pipeline, considering meshing and element design as a unique challenge, leading thus to a black-box pipeline, without any parameter tuning.
