    • Hierarchical Higher Order Face Cluster Radiosity for Global Illumination Walkthroughs of Complex Non-Diffuse Environments 

      Gobbetti, Enrico; Spano, Leonardo; Agus, Marco (Blackwell Publishers, Inc and the Eurographics Association, 2003)
      We present an algorithm for simulating global illumination in scenes composed of highly tessellated objects withdiffuse or moderately glossy reflectance. The solution method is a higher order extension of the face cluster ...

    • Hierarchical hp-Adaptive Signed Distance Fields 

      Koschier, Dan; Deul, Crispin; Bender, Jan (The Eurographics Association, 2016)
      In this paper we propose a novel method to construct hierarchical hp-adaptive Signed Distance Fields (SDFs). We discretize the signed distance function of an input mesh using piecewise polynomials on an axis-aligned ...

    • Hierarchical Image-Based Rendering using Texture Mapping Hardware 

      Max, Nelson; Deussen, Oliver; Keating, Brett (The Eurographics Association, 1999)
      Multi-layered depth images containing color and normal information for subobjects in a hierarchical scene model are precomputed with standard zbuffer hardware for six orthogonal views. These are adaptively selected according ...

    • Hierarchical Image-Space Radiosity for Interactive Global Illumination 

      Nichols, Greg; Shopf, Jeremy; Wyman, Chris (The Eurographics Association and Blackwell Publishing Ltd, 2009)
      We introduce image-space radiosity and a hierarchical variant as a method for interactively approximating diffuse indirect illumination in fully dynamic scenes. As oft observed, diffuse indirect illumination contains mainly ...

    • Hierarchical Impostors for the Flocking Algorithm in 3D 

      O'Hara, Noel (Blackwell Publishers, Inc and the Eurographics Association, 2002)
      The availability of powerful and affordable 3D PC graphics boards has made the rendering of rich immersiveenvironments possible at interactive speeds. The scene update rate and the appropriate behaviour of objects withinthe ...

    • Hierarchical Isosurface Segmentation Based on Discrete Curvature 

      Vivodtzev, Fabien; Linsen, Lars; Bonneau, Georges-Pierre; Hamann, Bernd; Joy, Kenneth I.; Olshausen, Bruno A. (The Eurographics Association, 2003)
      A high-level approach to describe the characteristics of a surface is to segment it into regions of uniform curvature behavior and construct an abstract representation given by a (topology) graph. We propose a surface ...

    • Hierarchical Link and Code: Efficient Similarity Search for Billion-Scale Image Sets 

      Yang, Kaixiang; Wang, Hongya; Du, Ming; Wang, Zhizheng; Tan, Zongyuan; Xiao, Yingyuan (The Eurographics Association, 2021)
      Similarity search is an indispensable component in many computer vision applications. To index billions of images on a single commodity server, Douze et al. introduced L&C that works on operating points considering 64-128 ...

    • Hierarchical Multi-Layer Screen-Space Ray Tracing 

      Hofmann, Nikolai; Bogendörfer, Phillip; Stamminger, Marc; Selgrad, Kai (ACM, 2017)
      In this paper we present a method for fast screen-space ray tracing. Single-layer screen-space ray marching is an established tool in high-performance applications, such as games, where plausible and appealing results are ...

    • Hierarchical Multiview Rigid Registration 

      Tang, Yizhi; Feng, Jieqing (The Eurographics Association and John Wiley & Sons Ltd., 2015)
      Registration is a key step in the 3D reconstruction of real-world objects. In this paper, we propose a hierarchical method for the rigid registration of multiple views. The multiview registration problem is solved via ...

    • Hierarchical Narrative Collage For Digital Photo Album 

      Zhang, Lei; Huang, Hua (The Eurographics Association and Blackwell Publishing Ltd., 2012)
      Collage can provide a summary form on the collection of photos in an album. In this paper, we introduce a novel approach to constructing photo collage in the hierarchical narrative manner. As opposed to previous methods ...

    • Hierarchical Opacity Optimization for Sets of 3D Line Fields 

      Günther, Tobias; Rössl, Christian; Theisel, Holger (The Eurographics Association and John Wiley and Sons Ltd., 2014)
      Abstract The selection of meaningful lines for 3D line data visualization has been intensively researched in recent years. Most approaches focus on single line fields where one line passes through each domain point. This ...

    • Hierarchical Penumbra Casting 

      Laine, Samuli; Aila, Timo (The Eurographics Association and Blackwell Publishing, Inc, 2005)

    • Hierarchical Perspective Volume Rendering Using Triangle Fans 

      Schussman, Greg; Max, Nelson (The Eurographics Association, 2001)
      We present a method of accelerated perspective volume rendering using cell projection, triangle fans, and a data hierarchy. The hierarchy allows mixed resolution rendering, greatly increasing speed. We utilize triangle ...

    • Hierarchical Planning and Control for Box Loco-Manipulation 

      Xie, Zhaoming; Tseng, Jonathan; Starke, Sebastian; Panne, Michiel van de; Liu, C. Karen (ACM Association for Computing Machinery, 2023)
      Humans perform everyday tasks using a combination of locomotion and manipulation skills. Building a system that can handle both skills is essential to creating virtual humans. We present a physically-simulated human capable ...
