A Unified Cloth Untangling Framework Through Discrete Collision Detection
(The Eurographics Association and John Wiley & Sons Ltd., 2016)We present an efficient and stable framework, called Unified Intersection Resolver (UIR), for cloth simulation systems where not only impending collisions but also pre-existing penetrations often arise. These two types of ... -
A Unified Discrete Framework for Intrinsic and Extrinsic Dirac Operators for Geometry Processing
(The Eurographics Association and John Wiley & Sons Ltd., 2018)Spectral mesh analysis and processing methods, namely ones that utilize eigenvalues and eigenfunctions of linear operators on meshes, have been applied to numerous geometric processing applications. The operator used ... -
Unified Neural Encoding of BTFs
(The Eurographics Association and John Wiley & Sons Ltd., 2020)Realistic rendering using discrete reflectance measurements is challenging, because arbitrary directions on the light and view hemispheres are queried at render time, incurring large memory requirements and the need for ... -
A Unified Neural Network for Panoptic Segmentation
(The Eurographics Association and John Wiley & Sons Ltd., 2019)In this paper, we propose a unified neural network for panoptic segmentation, a task aiming to achieve more fine-grained segmentation. Following existing methods combining semantic and instance segmentation, our method ... -
Unified Shape and SVBRDF Recovery using Differentiable Monte Carlo Rendering
(The Eurographics Association and John Wiley & Sons Ltd., 2021)Reconstructing the shape and appearance of real-world objects using measured 2D images has been a long-standing inverse rendering problem. In this paper, we introduce a new analysis-by-synthesis technique capable of producing ... -
A Unified Subdivision Scheme for Polygonal Modeling
(Blackwell Publishers Ltd and the Eurographics Association, 2001)Subdivision rules have traditionally been designed to generate smooth surfaces from polygonal meshes. In this paper we propose to employ subdivision rules as a polygonal modeling tool, specifically to add additional level ... -
A Unified, Object-Oriented Graphics System and Software Architecture for Visualising CAD/CAM Presentations
(Blackwell Science Ltd and the Eurographics Association, 1996)Most object-oriented graphics systems (OOGS) either support general purpose graphics capabilities (drawing editors, ray tracing, etc.), or have targeted specific areas of computer graphics, for example, interface building, ... -
Uniformization and Density Adaptation for Point Cloud Data Via Graph Laplacian
(© 2018 The Eurographics Association and John Wiley & Sons Ltd., 2018)Point cloud data is one of the most common types of input for geometric processing applications. In this paper, we study the point cloud density adaptation problem that underlies many pre‐processing tasks of points data. ... -
Unifying Color and Texture Transfer for Predictive Appearance Manipulation
(The Eurographics Association and John Wiley & Sons Ltd., 2015)Recent color transfer methods use local information to learn the transformation from a source to an exemplar image, and then transfer this appearance change to a target image. These solutions achieve very successful results ... -
Unifying Vector and Polygon Algorithms for Scan Conversion and Clipping
(Eurographics Association, 1987)In both scan conversion and clipping, algorithm for dealing with polygons are generally presented independently of those for vectors, although many of the operations performed are similar. This paper shows how polygon ... -
Universal Rendering Sequences for Transparent Vertex Caching of Progressive Meshes
(Blackwell Publishers Ltd and the Eurographics Association, 2002)We present methods to generate rendering sequences for triangle meshes which preserve mesh locality as much as possible. This is useful for maximizing vertex reuse when rendering the mesh using a FIFO vertex buffer, such ... -
Unpopping: Solving the Image-Space Blend Problem for Smooth Discrete LOD Transitions
(The Eurographics Association and Blackwell Publishing Ltd, 2007)This paper presents a new, simple and practical algorithm to avoid artifacts when switching between discrete levels of detail (LOD) by smoothly blending LOD representations in image space. We analyse the alternatives of ... -
Unsharp Masking, Countershading and Halos: Enhancements or Artifacts?
(The Eurographics Association and John Wiley and Sons Ltd., 2012)Countershading is a common technique for local image contrast manipulations, and is widely used both in automatic settings, such as image sharpening and tonemapping, as well as under artistic control, such as in paintings ... -
Unsteady Flow Visualization by Animating Evenly-Spaced Streamlines
(Blackwell Publishers Ltd and the Eurographics Association, 2000)In recent years the work on vector field visualization has been concentrated on LIC-based methods. In this paper we propose an alternative solution for the visualization of unsteady flow fields. Our approach is based on ... -
Unstructured Light Fields
(The Eurographics Association and John Wiley and Sons Ltd., 2012)We present a system for interactively acquiring and rendering light fields using a hand-held commodity camera. The main challenge we address is assisting a user in achieving good coverage of the 4D domain despite the ... -
Unsupervised Cycle-consistent Deformation for Shape Matching
(The Eurographics Association and John Wiley & Sons Ltd., 2019)We propose a self-supervised approach to deep surface deformation. Given a pair of shapes, our algorithm directly predicts a parametric transformation from one shape to the other respecting correspondences. Our insight is ... -
Unsupervised Deep Single-Image Intrinsic Decomposition using Illumination-Varying Image Sequences
(The Eurographics Association and John Wiley & Sons Ltd., 2018)Machine learning based Single Image Intrinsic Decomposition (SIID) methods decompose a captured scene into its albedo and shading images by using the knowledge of a large set of known and realistic ground truth decompositions. ... -
