Semantic Shape Editing with Parametric Implicit Templates
We propose a semantic shape editing method to edit 3D triangle meshes using parametric implicit surface templates, benefiting from the many advantages offered by analytical implicit representations, such as infinite resolution and boolean or blending opera ...
2024A method and system for enforcing smoothness constraints on surface meshes from a graph convolutional neural network
Pascal Fua, Pamuditha Udaranga Wickramasinghe
A method for enforcing smoothness constraints on surface meshes produced by a Graph Convolutional Neural Network (GCNN) including the steps of reading image data from a memory, the image data including two-dimensional image data representing a three-dimens ...
2023Leveraging the Snap Buckling of Bistable Magnetic Shells to Design a Refreshable Braille Dot
Pedro Miguel Nunes Pereira de Almeida Reis, Tian Chen, Arefeh Abbasi, Bastien Freddy Gustave Aymon
A design concept is proposed for the building block, a dot, of programmable braille readers utilizing bistable shell buckling, magnetic actuation, and pneumatic loading. The design process is guided by Finite Element simulations, which are initially valida ...
Hoboken2023HybridSDF: Combining Deep Implicit Shapes and Geometric Primitives for 3D Shape Representation and Manipulation
Pascal Fua, Nicolas Talabot, Subeesh Vasu, Artem Lukoianov
Deep implicit surfaces excel at modeling generic shapes but do not always capture the regularities present in manufactured objects, which is something simple geometric primitives are particularly good at. In this paper, we propose a representation combinin ...
2022Influence of Spatial Rendering on the Performance of Point Cloud Objective Quality Metrics
Touradj Ebrahimi, Michela Testolina
The use of point clouds to digitally represent three-dimensional objects with both geometry and color attributes is rapidly increasing in several applications. Since storage and transmission of uncompressed point cloud data are often impractical, several l ...
IEEE2022Neural Parts: Learning Expressive 3D Shape Abstractions with Invertible Neural Networks
Angelos Katharopoulos, Andreas Geiger, Despoina Paschalidou
Impressive progress in 3D shape extraction led to representations that can capture object geometries with high fidelity. In parallel, primitive-based methods seek to represent objects as semantically consistent part arrangements. However, due to the simpli ...
IEEE COMPUTER SOC2021Simulating Infiltration as a Sequence of Pinning and De-pinning Processes
Andreas Mortensen, William Craig Carter
The infiltration of a non-wetting liquid, such as molten metal, into a porous solid, such as a ceramic preform, is influenced by the wetting angle of the liquid on the solid. The link between local wetting and the minimum pressure required for initiation o ...
2021MATHICSE Technical Report: Immersed Boundary-Conformal Isogeometric Method for Linear Elliptic Problems
Annalisa Buffa, Pablo Antolin Sanchez, Xiaodong Wei
We present a novel isogeometric method, namely the Immersed Boundary-Conformal Method (IBCM), that features a layer of discretization conformal to the boundary while employing a simple background mesh for the remaining domain. In this manner, we leverage t ...

2021A Dexterous Soft Robotic Hand for Delicate In-Hand Manipulation
In this letter, we show that soft robotic hands provide a robust means of performing basic primitives of in-hand manipulation in the presence of uncertainty. We first discuss the design of a prototype hand with dexterous soft fingers capable of moving obje ...
