    • Finding Feature Similarities Between Geometric Trees 

      Mukherjee, Uddipan; Gopi, Meenakshisundaram (The Eurographics Association, 2014)
      Geometric trees are graphs with no cycles in which the nodes have spatial co-ordinates and the edges are geometric curves. Many physical systems can be represented effectively using geometric trees, e.g. river beds, animal ...
    • 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. ...
    • 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 ...
