    • Interactive 3D Painting on Point-Sampled Objects 

      Adams, Bart; Wicke, Martin; Dutré, Philip; Gross, Markus; Pauly, Mark; Teschner, Matthias (The Eurographics Association, 2004)
      We present a novel painting system for 3D objects. In order to overcome parameterization problems of existing applications, we propose a unified sample-based approach to represent geometry and appearance of the 3D object ...

    • Interactive Point-Based Modeling from Dense Color and Sparse Depth 

      Popescu, Voicu; Sacks, Elisha; Bahmutov, Gleb (The Eurographics Association, 2004)
      We are developing a system for interactive modeling of real world scenes. The acquisition device consists of a video camera enhanced with an attached laser system. As the operator sweeps the scene, the device acquires dense ...

    • Real-Time Point Cloud Refinement 

      Guennebaud, G.; Barthe, L.; Paulin, M. (The Eurographics Association, 2004)
      Splatting-based rendering techniques are currently the best choice for efficient high quality rendering of pointbased geometries. However, such techniques are not suitable for large magnification, especially when the object ...

    • Stratified Point Sampling of 3D Models 

      Nehab, Diego; Shilane, Philip (The Eurographics Association, 2004)
      Point sampling is an important intermediate step for a variety of computer graphics applications, and specialized sampling strategies have been developed to satisfy the requirements of each problem. In this article, we ...

    • Point-based Surface Rendering with Motion Blur 

      Guan, Xin; Mueller, Klaus (The Eurographics Association, 2004)
      In this paper we show how to extend point-based surface rendering to illustrate object motion. We do this by first extruding the circular points into ellipsoids, which fill the space traced out by the points in motion. ...

    • Phong Splatting 

      Botsch, Mario; Spernat, Michael; Kobbelt, Leif (The Eurographics Association, 2004)
      Surface splatting has developed into a valuable alternative to triangle meshes when it comes to rendering of highly detailed massive datasets. However, even highly accurate splat approximations of the given geometry may ...

    • Interactive Silhouette Rendering for Point-Based Models 

      Xu, Hui; Nguyen, Minh X.; Yuan, Xiaoru; Chen, Baoquan (The Eurographics Association, 2004)
      We present a new method for rendering silhouettes of point-based models. Due to the lack of connectivity information, most existing polygon-based silhouette generation algorithms cannot be applied to point-based models. ...

    • Boolean Operations on Surfel-Bounded Solids Using Programmable Graphics Hardware 

      Adams, Bart; Dutré, Philip (The Eurographics Association, 2004)
      In this paper we present an algorithm to compute boolean operations on free-form solids bounded by surfels using programmable graphics hardware. The intersection, union and difference of two or more solids, is calculated ...

    • Multi-Resolution Sound Rendering 

      Wand, M.; Straßer, W. (The Eurographics Association, 2004)
      Point-based multi-resolution representations have been used successfully for rendering highly complex three dimensional scenes in real-time. In this paper, we apply this paradigm to sound rendering: A hierarchy of stochastic ...
