    • 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 ...

    • Hierarchical Planning and Control for Complex Motor Tasks 

      Zimmermann, Daniel; Coros, Stelian; Ye, Yuting; Sumner, Robert W.; Gross, Markus (ACM Siggraph, 2015)
      We present a planning and control framework that enables physically simulated characters to perform various types of motor tasks. To create physically-valid motion plans, our method uses a hierarchical set of simplified ...

    • Hierarchical Poisson-Disk Sampling for Fiber Stipples 

      Hlawitschka, Mario; Goldau, Mathias; Wiebel, Alexander; Heine, Christian; Scheuermann, Gerik (The Eurographics Association, 2013)
      To understand neural tracts of the brain, neuroscientists use visualizations of diffusion data. Fiber stippling - a technique inspired by illustrations - accommodates probabilistic tracts, main diffusion direction, and ...

    • Hierarchical Position Based Dynamics 

      Müller, Matthias (The Eurographics Association, 2008)
      The Position Based Dynamics approach (PBD) recently introduced allows robust simulations of dynamic systems in real time. The simplicity of the method is due to the fact, that the solver processes the constraints one by ...

    • Hierarchical Quad Meshing of 3D Scanned Surfaces 

      Bukenberger, Dennis R.; Lensch, Hendrik P. A. (The Eurographics Association and John Wiley & Sons Ltd., 2018)
      In this paper we present a novel method to reconstruct watertight quad meshes on scanned 3D geometry. There exist many different approaches to acquire 3D information from real world objects and sceneries. Resulting point ...

    • Hierarchical Radiosity for Dynamic Environments 

      Shaw, Erin (Blackwell Publishers Ltd and the Eurographics Association, 1997)
      This paper extends the hierarchical radiosity method to environments in which geometry and surface attributes can be changed dynamically. New algorithms are presented for maintaining an appropriately-sized mesh and speeding ...

    • Hierarchical Radiosity for Procedural Urban Environments 

      Roure, Ferran; Besuievsky, Gonzalo; Patow, Gustavo (The Eurographics Association, 2014)
      In this paper we present a novel solution for the computation of diffuse global illumination in urban environments that takes advantage of the underlying structure of the procedural building models used for generating the ...

    • Hierarchical Raster Occlusion Culling 

      Lee, Gi Beom; Jeong, Moonsoo; Seok, Yechan; Lee, Sungkil (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 

      Dokter, Mark; Hladký, Jozef; Parger, Mathias; Schmalstieg, Dieter; Seidel, Hans-Peter; Steinberger, Markus (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 

      Noe, N.; Peroche, B. (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, ...
