      A Texture Atlas is a two dimensional representation of a 3D model usable for paint systems or as a sewing pattern.The field of texture atlas generation from polygonal models has been well exploited in the recent years. The ...
    • BDAM - Batched Dynamic Adaptive Meshes for High Performance Terrain Visualization 

      Cignoni, P.; Ganovelli, F.; Gobbetti, E.; Marton, F.; Ponchio, F.; Scopigno, R. (Blackwell Publishers, Inc and the Eurographics Association, 2003)
      This paper describes an efficient technique for out-of-core rendering and management of large textured terrainsurfaces. The technique, called Batched Dynamic Adaptive Meshes (BDAM), is based on a paired tree structure:a ...
    • Beyond Stippling - Methods for Distributing Objects on the Plane 

      Hiller, Stefan; Hellwig, Heino; Deussen, Oliver (Blackwell Publishers, Inc and the Eurographics Association, 2003)
      Conventionally, stippling is an effective technique for representing surfaces in pen-and-ink. We present new efficientmethods for stipple drawings by computer. In contrast to already existing techniques, arbitrary shapes ...
    • Cloth Motion Capture 

      Pritchard, D.; Heidrich, W. (Blackwell Publishers, Inc and the Eurographics Association, 2003)
      Recent years have seen an increased interest in motion capture systems. Current systems, however, are limitedto only a few degrees of freedom, so that effectively only the motion of linked rigid bodies can be acquired. ...
    • 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 ...
    • Fast Photo-Realistic Rendering of Trees in Daylight 

      Qin, Xueying; Nakamae, Eihachiro; Tadamura, Katsumi; Nagai, Yasuo (Blackwell Publishers, Inc and the Eurographics Association, 2003)
      We propose a fast approach for photo-realistic rendering of trees under various kinds of daylight, which is particularlyuseful for the environmental assessment of landscapes. In our approach the 3D tree models are transformedto ...
    • A Fast Rendering Method for Refractive and Reflective Caustics Due to Water Surfaces 

      Iwasaki, Kei; Dobashi, Yoshinori; Nishita, Tomoyuki (Blackwell Publishers, Inc and the Eurographics Association, 2003)
      In order to synthesize realistic images of scenes that include water surfaces, the rendering of optical effectscaused by waves on the water surface, such as caustics and reflection, is necessary. However, rendering causticsis ...
    • A Few Good Lines: Suggestive Drawing of 3D Models 

      Sousa, Mario Costa; Prusinkiewicz, Przemyslaw (Blackwell Publishers, Inc and the Eurographics Association, 2003)
