  • 3D Discrete Skeleton Generation by Wave Propagation on PR-Octree for Finite Element Mesh Sizing 

    Quadros, W. R.; Shimada, K.; Owen, S. J. (The Eurographics Association, 2004)
    This paper proposes a new algorithm to generate a disconnected, three-dimensional (3D) skeleton and an application of such a skeleton to generate a finite element (FE) mesh sizing function of a solid. The mesh sizing ...
  • Connected and Manifold Sierpinski Polyhedra 

    Akleman, E.; Srinivasan, V. (The Eurographics Association, 2004)
    In this paper, we present a subdivision-inspired scheme to construct generalized Sierpinski polyhedron. Unlike usual Sierpinski polyhedra construction schemes, which create either an infinite set of disconnected tetrahedra ...
  • Image Based Bio-CAD Modeling and Its Applications to Biomedical and Tissue Engineering 

    Starly, B.; Darling, A.; Gomez, C.; Nam, J.; Sun, W.; Shokoufandeh, A.; Regli, W. (The Eurographics Association, 2004)
    CAD has been traditionally used to assist in engineering design and modeling for representation, analysis and manufacturing. Advances in Information Technology and in Biomedicine have created new uses for CAD with many ...
  • Compression, Segmentation, and Modeling of Filamentary Volumetric Data 

    McCormick, B.; Busse, B.; Doddapaneni, P.; Melek, Z.; Keyser, J. (The Eurographics Association, 2004)
    We present a data structure for the representation of filamentary volumetric data, called the L-block. While the L-block can be used to represent arbitrary volume data sets, it is particularly geared towards representing ...
  • Plumber: A Multi-scale Decomposition of 3D Shapes into Tubular Primitives and Bodies 

    Mortara, M.; Patane, G.; Spagnuolo, M.; Falcidieno, B.; Rossignac, J. (The Eurographics Association, 2004)
    Plumber is a specialized shape classi cation method for detecting tubular features of 3D objects represented by a triangle mesh. The Plumber algorithm segments a surface into connected components that are either body parts ...
  • Actual Morphing: A Physical-Based Approach for Blending Two 2D/3D Shapes 

    Hu, S. M.; Li, C. F.; Zhang, H. (The Eurographics Association, 2004)
    When two topologically identical shapes are blended, various possible transformation paths exist from the source shape to the target shape. Which one is the most plausible? Here we propose that the transformation process ...
  • Euler Operators for Stratified Objects with Incomplete Boundaries 

    Gomes, A. J. P. (The Eurographics Association, 2004)
    Stratified objects such as those found in geometry-based systems (e.g. CAD systems and animation systems) can be stepwise constructed and manipulated through Euler operators. The operators proposed in this paper extend ...
  • Handling Degeneracies in Exact Boundary Evaluation 

    Ouchi, K.; Keyser, J. (The Eurographics Association, 2004)
    We present a method for dealing with degenerate situations in an exact boundary evaluation system. We describe the possible degeneracies that can arise and how to detect them. We then present a numeric perturbation method ...

    Hwang, T. J.; Lee, K.; Jeong, J. H.; Oh, H. Y. (The Eurographics Association, 2004)
    Custom-tailored products are defined as products having various sizes and shapes tailored to meet the customer's different tastes or needs. Thus fabrication of custom-tailored products inherently involves inefficiency. To ...
  • Contour Interpolation with Bounded Dihedral Angles 

    Bereg, S.; Jiang, M.; Zhu, B. (The Eurographics Association, 2004)
    In this paper, we present the first nontrivial theoretical bound on the quality of the 3D solids generated by any contour interpolation method. Given two arbitrary parallel contour slices with n vertices in 3D, let a be ...
  • Using Cayley Menger Determinants 

    Michelucci, D.; Foufou, S. (The Eurographics Association, 2004)
    We use Cayley-Menger Determinants (CMDs) to obtain an intrinsic formulation of geometric constraints. First, we show that classical CMDs are very convenient to solve the Stewart platform problem. Second, issues like distances ...

    Michelucci, D.; Neveu, M. (The Eurographics Association, 2004)
    Abstract A polynomial method is described for computing the shortest circuit with a prescribed homotopy on a surface. The surface is not described by a mesh but by a constellation: a set of sampling points. Points close ...

    Varley, P. A. C.; Martin, R. R.; Suzuki, H. (The Eurographics Association, 2004)
    Automatic creation of B-rep models of engineering objects from freehand sketches would benefit designers. A subgoal is to take a single line drawing (with hidden lines removed), and from it deduce an initial 3D geometric ...
