    • Smooth Subdivision of Tetrahedral Meshes 

      Schaefer, S.; Hakenberg, J.; Warren, J. (The Eurographics Association, 2004)
      We describe a new subdivision scheme for unstructured tetrahedral meshes. Previous tetrahedral schemes based on generalizations of box splines have encoded arbitrary directional preferences in their associated subdivision ...

    • Fast Collision Detection between Massive Models using Dynamic Simplification 

      Yoon, Sung-Eui; Salomon, Brian; Lin, Ming; Manocha, Dinesh (The Eurographics Association, 2004)
      We present a novel approach for collision detection between large models composed of tens of millions of polygons. Each model is represented as a clustered hierarchy of progressive meshes (CHPM). The CHPM is a dual hierarchy ...

    • Spectral Surface Reconstruction From Noisy Point Clouds 

      Kolluri, Ravikrishna; Shewchuk, Jonathan Richard; O'Brien, James F. (The Eurographics Association, 2004)
      We introduce a noise-resistant algorithm for reconstructing a watertight surface from point cloud data. It forms a Delaunay tetrahedralization, then uses a variant of spectral graph partitioning to decide whether each ...

    • Connectivity Transformation for Mesh Metamorphosis 

      Ahn, Minsu; Lee, Seungyong; Seidel, Hans-Peter (The Eurographics Association, 2004)
      In previous mesh morphing techniques, the vertex set and connectivity of an in-between mesh are fixed and only the vertex positions are interpolated between input meshes. With this restriction, to accurately represent both ...

    • Similarity-Based Surface Modelling Using Geodesic Fans 

      Zelinka, Steve; Garland, Michael (The Eurographics Association, 2004)
      We present several powerful new techniques for similarity-based modelling of surfaces using geodesic fans, a new framework for local surface comparison. Similarity-based surface modelling provides intelligent surface ...
