In-the-wild Material Appearance Editing using Perceptual Attributes
(The Eurographics Association and John Wiley & Sons Ltd., 2023)Intuitively editing the appearance of materials from a single image is a challenging task given the complexity of the interactions between light and matter, and the ambivalence of human perception. This problem has been ... -
A Variational Loop Shrinking Analogy for Handle and Tunnel Detection and Reeb Graph Construction on Surfaces
(The Eurographics Association and John Wiley & Sons Ltd., 2023)The humble loop shrinking property played a central role in the inception of modern topology but it has been eclipsed by more abstract algebraic formalisms. This is particularly true in the context of detecting relevant ... -
Robust Pointset Denoising of Piecewise-Smooth Surfaces through Line Processes
(The Eurographics Association and John Wiley & Sons Ltd., 2023)Denoising is a common, yet critical operation in geometry processing aiming at recovering high-fidelity models of piecewisesmooth objects from noise-corrupted pointsets. Despite a sizable literature on the topic, there is ... -
Surface Maps via Adaptive Triangulations
(The Eurographics Association and John Wiley & Sons Ltd., 2023)We present a new method to compute continuous and bijective maps (surface homeomorphisms) between two or more genus-0 triangle meshes. In contrast to previous approaches, we decouple the resolution at which a map is ... -
Evolving Guide Subdivision
(The Eurographics Association and John Wiley & Sons Ltd., 2023)To overcome the well-known shape deficiencies of bi-cubic subdivision surfaces, Evolving Guide subdivision (EG subdivision) generalizes C2 bi-quartic (bi-4) splines that approximate a sequence of piecewise polynomial surface ... -
Simulating Analogue Film Damage to Analyse and Improve Artefact Restoration on High-resolution Scans
(The Eurographics Association and John Wiley & Sons Ltd., 2023)Digital scans of analogue photographic film typically contain artefacts such as dust and scratches. Automated removal of these is an important part of preservation and dissemination of photographs of historical and cultural ... -
Learning to Learn and Sample BRDFs
(The Eurographics Association and John Wiley & Sons Ltd., 2023)We propose a method to accelerate the joint process of physically acquiring and learning neural Bi-directional Reflectance Distribution Function (BRDF) models. While BRDF learning alone can be accelerated by meta-learning, ... -
Subpixel Deblurring of Anti-Aliased Raster Clip-Art
(The Eurographics Association and John Wiley & Sons Ltd., 2023)Artist generated clip-art images typically consist of a small number of distinct, uniformly colored regions with clear boundaries. Legacy artist created images are often stored in low-resolution (100x100px or less) ... -
What's in a Decade? Transforming Faces Through Time
(The Eurographics Association and John Wiley & Sons Ltd., 2023)How can one visually characterize photographs of people over time? In this work, we describe the Faces Through Time dataset, which contains over a thousand portrait images per decade from the 1880s to the present day. Using ... -
Online Avatar Motion Adaptation to Morphologically-similar Spaces
(The Eurographics Association and John Wiley & Sons Ltd., 2023)In avatar-mediated telepresence systems, a similar environment is assumed for involved spaces, so that the avatar in a remote space can imitate the user's motion with proper semantic intention performed in a local space. ... -
One Step Further Beyond Trilinear Interpolation and Central Differences: Triquadratic Reconstruction and its Analytic Derivatives at the Cost of One Additional Texture Fetch
(The Eurographics Association and John Wiley & Sons Ltd., 2023)Recently, it has been shown that the quality of GPU-based trilinear volume resampling can be significantly improved if the six additional trilinear samples evaluated for the gradient estimation also contribute to the ... -
Stochastic Subsets for BVH Construction
(The Eurographics Association and John Wiley & Sons Ltd., 2023)BVH construction is a critical component of real-time and interactive ray-tracing systems. However, BVH construction can be both compute and bandwidth intensive, especially when a large degree of dynamic geometry is present. ... -
Learning to Transfer In-Hand Manipulations Using a Greedy Shape Curriculum
(The Eurographics Association and John Wiley & Sons Ltd., 2023)In-hand object manipulation is challenging to simulate due to complex contact dynamics, non-repetitive finger gaits, and the need to indirectly control unactuated objects. Further adapting a successful manipulation skill ... -
An Optimization-based SPH Solver for Simulation of Hyperelastic Solids
(The Eurographics Association and John Wiley & Sons Ltd., 2023)This paper proposes a novel method for simulating hyperelastic solids with Smoothed Particle Hydrodynamics (SPH). The proposed method extends the coverage of the state-of-the-art elastic SPH solid method to include different ... -
Unsupervised Template Warp Consistency for Implicit Surface Correspondences
(The Eurographics Association and John Wiley & Sons Ltd., 2023)Unsupervised template discovery via implicit representation in a category of shapes has recently shown strong performance. At the core, such methods deform input shapes to a common template space which allows establishing ... -
Interactive Depixelization of Pixel Art through Spring Simulation
(The Eurographics Association and John Wiley & Sons Ltd., 2023)We introduce an approach for converting pixel art into high-quality vector images. While much progress has been made on automatic conversion, there is an inherent ambiguity in pixel art, which can lead to a mismatch with ... -
EUROGRAPHICS 2023: CGF 42-2 Frontmatter

Makeup Extraction of 3D Representation via Illumination-Aware Image Decomposition
(The Eurographics Association and John Wiley & Sons Ltd., 2023)Facial makeup enriches the beauty of not only real humans but also virtual characters; therefore, makeup for 3D facial models is highly in demand in productions. However, painting directly on 3D faces and capturing real-world ... -
Scalable and Efficient Functional Map Computations on Dense Meshes
(The Eurographics Association and John Wiley & Sons Ltd., 2023)We propose a new scalable version of the functional map pipeline that allows to efficiently compute correspondences between potentially very dense meshes. Unlike existing approaches that process dense meshes by relying on ... -
Interactive Design of 2D Car Profiles with Aerodynamic Feedback
(The Eurographics Association and John Wiley & Sons Ltd., 2023)The design of car shapes requires a delicate balance between aesthetic and performance. While fluid simulation provides the means to evaluate the aerodynamic performance of a given shape, its computational cost hinders its ...
