Hierarchical Raster Occlusion Culling
(The Eurographics Association and John Wiley & Sons Ltd., 2021)This paper presents a scalable online occlusion culling algorithm, which significantly improves the previous raster occlusion culling using object-level bounding volume hierarchy. Given occluders found with temporal ... -
Hierarchical Rasterization of Curved Primitives for Vector Graphics Rendering on the GPU
(The Eurographics Association and John Wiley & Sons Ltd., 2019)In this paper, we introduce the CPatch, a curved primitive that can be used to construct arbitrary vector graphics. A CPatch is a generalization of a 2D polygon: Any number of curves up to a cubic degree bound a primitive. ... -
Hierarchical Reconstruction of BRDFs using Locally Supported Functions
(Blackwell Publishers Ltd and the Eurographics Association, 2000)BRDFs are the backbone of realistic rendering algorithms. Analytical models are sometimes ineffective since they frequently cannot represent very particular material characteristics (retro-reflection, anisotropy, ... -
Hierarchical Retargetting of 2D Motion Fields to the Animation of 3D Plant Models
(The Eurographics Association, 2006)The complexity of animating trees, shrubs and foliage is an impediment to the efficient and realistic depiction of natural environments. This paper presents an algorithm to extract, from a single video sequence, motion ... -
Hierarchical Retargetting of Fine Facial Motions
(The Eurographics Association and Blackwell Publishing, Inc, 2004)We present a novel technique for retargetting captured facial animation to new facial models. We use dense motion data that can express fine motions such as wrinkles. We use a normal mesh, which is a special multi-resolution ... -
A Hierarchical Segmentation of Articulated Bodies
(The Eurographics Association and Blackwell Publishing Ltd, 2008)This paper presents a novel segmentation method to assist the rigging of articulated bodies. The method computes a coarse-to-fine hierarchy of segments ordered by the level of detail. The results are invariant to deformations, ... -
A Hierarchical Shadow Volume Algorithm
(The Eurographics Association, 2004)The shadow volume algorithm is a popular technique for real-time shadow generation using graphics hardware. Its major disadvantage is that it is inherently fillrate-limited, as the performance is inversely proportional to ... -
Hierarchical Stochastic Motion Blur Rasterization
(ACM, 2011)We present a hierarchical traversal algorithm for stochastic rasterization of motion blur, which efficiently reduces the number of inside tests needed to resolve spatio-temporal visibility. Our method is based on novel ... -
Hierarchical Stochastic Neighbor Embedding
(The Eurographics Association and John Wiley & Sons Ltd., 2016)In recent years, dimensionality-reduction techniques have been developed and are widely used for hypothesis generation in Exploratory Data Analysis. However, these techniques are confronted with overcoming the trade-off ... -
Hierarchical Structure Recovery of Point-Sampled Surfaces
(The Eurographics Association and Blackwell Publishing Ltd, 2010)We focus on the class of regular models defined by Varady et al. for reverse engineering purposes. Given a 3D surface represented through a dense set of points, we present a novel algorithm that converts to a hierarchical ... -
Hierarchical Texture Synthesis on 3-D Surfaces
(Eurographics Association, 1989)This paper presents a new method for synthesizing hierarchical textures on 3-D surfaces. This method utilizes both a mapping technique for rendering the macroscopic structure on the surface and a generalization of the ... -
A Hierarchical Topology-Based Model for Handling Complex Indoor Scenes
(The Eurographics Association and Blackwell Publishing Ltd, 2006)This paper presents a topology-based representation dedicated to complex indoor scenes. It accounts for memory management and performances during modelling, visualization and lighting simulation. We propose to enlarge a ... -
Hierarchical Visualization and Compression of Large Volume Datasets Using GPU Clusters
(The Eurographics Association, 2004)We describe a system for the texture-based direct volume visualization of large data sets on a PC cluster equipped with GPUs. The data is partitioned into volume bricks in object space, and the intermediate images are ... -
Hierarchical Vortex Regions in Swirling Flow
(The Eurographics Association and Blackwell Publishing Ltd., 2009)We propose a new criterion to characterize hierarchical two-dimensional vortex regions induced by swirling motion. Central to the definition are closed loops that intersect the flow field at a constant angle. The union of ... -
Hierarchical Vorticity Skeletons
(ACM, 2017)We propose a novel method to extract hierarchies of vortex filaments from given three-dimensional flow velocity fields. We call these collections of filaments Hierarchical Vorticity Skeletons (HVS). They extract multi-scale ... -
Hierarchyless Simplification, Stripification and Compression of Triangulated Two-Manifolds

HiFiVE: A Hilbert Space Embedding of Fiber Variability Estimates for Uncertainty Modeling and Visualization
(The Eurographics Association and Blackwell Publishing Ltd., 2013)Obtaining reproducible fiber direction estimates from diffusion MRI is crucial for successful fiber tracking. Modeling and visualizing the probability distribution of the inferred fiber directions is an important step in ... -
HIFUpm: a Visual Environment to Plan and Monitor High Intensity Focused Ultrasound Treatments
(The Eurographics Association, 2019)High Intensity Focused Ultrasound (HIFU) is a non invasive therapeutic method, which has been a subject of interest for the treatment of various kinds of tumors. Despite the numerous advantages, HIFU techniques do not reach ... -
HIFUtk: Visual Analytics for High Intensity Focused Ultrasound Simulation
(The Eurographics Association, 2017)Magnetic Resonance-guided High Intensity Focused Ultrasound (MR-HIFU) is a novel and non-invasive therapeutic method. It can be used to locally increase the temperature in a target position in the human body. HIFU procedures ... -
High Dynamic Range Display of Authentically Illuminated Byzantine Art from Cyprus
