      This paper proposes a geometric iteration algorithm for computing point projection and inversion on surfaces based on local biarc approximation. The iteration begins with initial estimation of the projection of the prescribed ...
    • Surface Mesh Segmentation and Reconstruction with Smooth Boundary Curves 

      Tsuchie, Shoichi; Higashi, Masatake (The Eurographics Association, 2014)
      In mesh segmentation for industrial design objects, each segment defined by a region with closed boundary should correspond to its underlying surface constructed according to the designer's intention. In order to generate ...
    • Integrating Occlusion Culling into LOD on GPU 

      Peng, Chao (The Eurographics Association, 2014)
      Real-time rendering of complex 3D models is still a very challenging task. Recently, GPU-based level-of-detail (LOD) approaches have been proposed to fast decrease the complexity of a 3D model, but applying only LOD ...
    • Visibility Filtering for Producing Indirect Illumination 

      Chen, Yu-Jung; Yen, Chen-Yu; Chen, Yen-Yu; Chen, Wei-Chao; Chien, Shao-Yi (The Eurographics Association, 2014)
      Indirect illumination is one of the most visually significant effects for a synthesized image. In order to render such effects at interactive rates, it is important to resolve the visibility between surfaces efficiently. ...
    • Scene Segmentation and Understanding for Context-Free Point Clouds 

      Spina, Sandro; Debattista, Kurt; Bugeja, Keith; Chalmers, Alan (The Eurographics Association, 2014)
      The continuous development of new commodity hardware intended to capture the surface structure of objects is quickly making point cloud data ubiquitous. Scene understanding methods address the problem of determining the ...
