    • Compressing Fluid Subspaces 

      Jones, Aaron Demby; Sen, Pradeep; Kim, Theodore (The Eurographics Association, 2016)
      Subspace fluid simulations, also known as reduced-order simulations, can be extremely fast, but also require basis matrices that consume an enormous amount of memory. Motivated by the extreme sparsity of Laplacian ...

    • Compression and Importance Sampling of Near-Field Light Sources 

      Mas, Albert; Martin, Ignacio; Patow, Gustavo (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      This paper presents a method for compressing measured datasets of the near-field emission of physical light sources (represented by raysets). We create a mesh on the bounding surface of the light source that stores ...

    • Compression and Real-Time Rendering of Inward Looking Spherical Light Fields 

      Hajisharif, Saghi; Miandji, Ehsan; Baravadish, Gabriel; Larsson, Per; Unger, Jonas (The Eurographics Association, 2020)
      Photorealistic rendering is an essential tool for immersive virtual reality. In this regard, the data structure of choice is typically light fields since they contain multidimensional information about the captured environment ...

    • Compression and Rendering of Textured Point Clouds via Sparse Coding 

      Schuster, Kersten; Trettner, Philip; Schmitz, Patric; Schakib, Julian; Kobbelt, Leif (The Eurographics Association, 2021)
      Splat-based rendering techniques produce highly realistic renderings from 3D scan data without prior mesh generation. Mapping high-resolution photographs to the splat primitives enables detailed reproduction of surface ...

    • Compression Domain Volume Rendering for Distributed Environments 

      Lippert, L.; Gross, M.H.; Kurmann, C. (Blackwell Publishers Ltd and the Eurographics Association, 1997)
      This paper describes a method for volume data compression and rendering which bases on wavelet splats. The underlying concept is especially designed for distributed and networked applications, where we assume a remote ...

    • Compression Of 16K Video For Mobile VR Playback Over 4K Streams 

      Vazquez, Iker; Cutchin, Steve (The Eurographics Association, 2018)
      Mobile virtual reality headset devices are currently constrained to playing back 4K video streams for hardware, network, and performance reasons. This strongly limits the quality of 360 degrees videos over 4K streams; which ...

    • Compression of 2D Vector Fields Under Guaranteed Topology Preservation 

      Theisel, H.; Rossl, Ch.; Seidel, H.-P. (Blackwell Publishers, Inc and the Eurographics Association, 2003)
      In this paper we introduce a new compression technique for 2D vector fields which preserves the complete topology, i.e., the critical points and the connectivity of the separatrices. As the theoretical foundation of the ...

    • Compression of Dense and Regular Point Clouds 

      Merry, Bruce; Marais, Patrick; Gain, James (The Eurographics Association and Blackwell Publishing Ltd, 2006)
      We present a simple technique for single-rate compression of point clouds sampled from a surface, based on a spanning tree of the points. Unlike previous methods, we predict future vertices using both a linear predictor, ...

    • Compression of Human Motion Capture Data Using Motion Pattern Indexing 

      Gu, Qin; Peng, Jingliang; Deng, Zhigang (The Eurographics Association and Blackwell Publishing Ltd, 2009)
      In this work, a novel scheme is proposed to compress human motion capture data based on hierarchical structure construction and motion pattern indexing. For a given sequence of 3D motion capture data of human body, the 3D ...

    • Compression of Large-Scale Terrain Data for Real-Time Visualization Using a Tiled Quad Tree 

      Platings, M.; Day, A. M. (The Eurographics Association and Blackwell Publishing Ltd., 2004)
      The aim of the rapid world modeling project is to implement a system to visualize the topography of the entire world on consumer-level hardware. This presents a significant problem in terms of both storage requirements and ...

    • Compression of Non-Manifold Polygonal Meshes Revisited 

      Buelow, Max von; Guthe, Stefan; Goesele, Michael (The Eurographics Association, 2017)
      Polygonal meshes are used in various fields ranging from CAD to gaming and web based applications. Reducing the size required for storing and transmitting these meshes by taking advantage of redundancies is an important ...

    • Compression of Point-Based 3D Models by Shape-Adaptive Wavelet Coding of Multi-Height Fields 

      Ochotta, Tilo; Saupe, Dietmar (The Eurographics Association, 2004)
      In order to efficiently archive and transmit large 3D models, lossy and lossless compression methods are needed. We propose a compression scheme for coordinate data of point-based 3D models of surfaces. A point-based model ...
