Glint Rendering based on a Multiple-Scattering Patch BRDF
(The Eurographics Association and John Wiley & Sons Ltd., 2019)Rendering materials such as metallic paints, scratched metals and rough plastics requires glint integrators that can capture all micro-specular highlights falling into a pixel footprint, faithfully replicating surface ... -
Global and Local Mesh Morphing for Complex Biological Objects from µCT Data
(The Eurographics Association, 2018)We show how biologically coherent mesh models of animals can be created from µCT data to generate artificial yet naturally looking intermediate objects. The whole pipeline of processing algorithms is presented, starting ... -
Global Conformal Surface Parameterization
(The Eurographics Association, 2003)We solve the problem of computing global conformal parameterizations for surfaces with nontrivial topologies. The parameterization is global in the sense that it preserves the conformality everywhere except for a few points, ... -
Global Consistency in the Automatic Assembly of Fragmented Artefacts
(The Eurographics Association, 2011)Automatic reconstruction of fragmented objects is of great interest in archaeology, where artefacts are often found in a fractured state. In this paper, we focus on the problem of automatically agglomerating clusters of ... -
Global Contrast Factor - a New Approach to Image Contrast
(The Eurographics Association, 2005)Contrast in image processing is usually defined as a ratio between the darkest and the brightest spots of an image. In this paper we introduce a different contrast definition. The newly introduced Global Contrast Factor ... -
Global Correspondence Optimization for Non-Rigid Registration of Depth Scans
(The Eurographics Association and Blackwell Publishing Ltd, 2008)We present a registration algorithm for pairs of deforming and partial range scans that addresses the challenges of non-rigid registration within a single non-linear optimization. Our algorithm simultaneously solves for ... -
Global Feature Tracking and Similarity Estimation in Time-Dependent Scalar Fields
(The Eurographics Association and John Wiley & Sons Ltd., 2017)We present an algorithm for tracking regions in time-dependent scalar fields that uses global knowledge from all time steps for determining the tracks. The regions are defined using merge trees, thereby representing a ... -
Global Illumination Animation with Random Radiance Representation
(The Eurographics Association, 2003)This paper proposes a non-diffuse global illumination algorithm that is fast enough to be appropriate for interactive walkthroughs and general animations. To meet the severe performance requirements, we heavily exploit ... -
Global Illumination as a Combination of Continuous Random Walk and Finite-Element Based Iteration
(Blackwell Publishers Ltd and the Eurographics Association, 2001)The paper introduces a global illumination method that combines continuous and finite-element approaches, pre-serving the speed of finite-element based iteration and the accuracy of continuous random walks. The basic idea ... -
Global Illumination Compensation for Spatially Augmented Reality
(The Eurographics Association and Blackwell Publishing Ltd, 2010)When projectors are used to display images on complex, non-planar surface geometry, indirect illumination between the surfaces will disrupt the final appearance of this imagery, generally increasing brightness, decreasing ... -
Global Illumination for Interactive Applications and High-Quality Animations
(Eurographics Association, 2002)One of the main obstacles to the use of global illumination in image synthesis industry is the considerable amount of time needed to compute the lighting for a single image. Until now, this computational cost has prevented ... -
Global Illumination for the Masses
(The Eurographics Association, 2007)Global Illumination (GI) algorithms came to fruition in the Graphics labs of USA, Europe, Japan, and beyond, during the 1980s and 1990s. The researchers who developed the algorithms had expert knowledge of the underlying ... -
Global Illumination Shadow Layers
(The Eurographics Association and John Wiley & Sons Ltd., 2019)Computer graphics artists often resort to compositing to rework light effects in a synthetic image without requiring a new render. Shadows are primary subjects of artistic manipulation as they carry important stylistic ... -
Global Illumination using Parallel Global Ray-Bundles
(The Eurographics Association, 2010)A fast computation of unbiased global illumination is still an unsolved problem, especially if multiple bounces of light and non-diffuse materials are included. The standard Monte Carlo methods are time-consuming, because ... -
Global Illumination using Photon Ray Splatting
(The Eurographics Association and Blackwell Publishing Ltd, 2007)We present a novel framework for efficiently computing the indirect illumination in diffuse and moderately glossy scenes using density estimation techniques. Many existing global illumination approaches either quickly ... -
Global Illumination Using Well‐Separated Pair Decomposition
(Copyright © 2015 The Eurographics Association and John Wiley & Sons Ltd., 2015)Instant radiosity methods rely on using a large number of virtual point lights (VPLs) to approximate global illumination. Efficiency considerations require grouping the VPLs into a small number of clusters that are treated ... -
Global Illumination-Aware Stylised Shading
(The Eurographics Association and John Wiley & Sons Ltd., 2021)Our aim is to convert an object's appearance to an arbitrary colour considering the light scattering in the entire scene, which is often called the global illumination. Existing stylisation methods convert the colour of ... -
Global Intrinsic Symmetries of Shapes
(The Eurographics Association and Blackwell Publishing Ltd, 2008)Although considerable attention in recent years has been given to the problem of symmetry detection in general shapes, few methods have been developed that aim to detect and quantify the intrinsic symmetry of a shape rather ... -
Global Landmarks Do Not Necessarily Improve Spatial Performance in Addition to Bodily Self-Movement Cues when Learning a Large-Scale Virtual Environment
(The Eurographics Association, 2015)Comparing spatial performance in different virtual reality setups can indicate which cues are relevant for a realistic virtual experience. Bodily self-movement cues and global orientation information were shown to increase ... -
A Global Optimization Approach to High-detail Reconstruction of the Head
(The Eurographics Association, 2011)The paper presents an approach for reconstructing head-and-shoulder portraits of people from calibrated stereo images with a high level of geometric detail. In contrast to many existing systems, our reconstructions cover ...
