    • Tolerance Envelopes of Planar Parametric Part Models 

      Ostrovsky-Berman, Y.; Joskowicz, L. (The Eurographics Association, 2004)
      We present a framework for the systematic study of parametric variation in planar mechanical parts and for ef ciently computing approximations of their tolerance envelopes. Part features are speci ed by explicit functions ...
    • Topological and Geometric Beautification of Reverse Engineered Geometric Models 

      Langbein, F. C.; Marshall, A. D.; Martin, R. R.; Mills, B. I.; Gao, C. H. (The Eurographics Association, 2004)
      Boundary representation models reverse engineered from 3D range data suffer from various inaccuracies caused by noise in the measured data and the model building software. Beauti cation aims to improve such models in a ...
    • Tracing Surface Intersection with a Validated ODE System Solver 

      Mukundan, H.; Ko, K. H.; Maekawa, T.; Sakkalis, T.; Patrikalakis, N. M. (The Eurographics Association, 2004)
      This paper presents a robust method for tracing intersection curve segments between continuous rational parametric surfaces, typically rational polynomial parametric surface patches. The tracing procedure is based on a ...
    • Update Operations on 3D Simplicial Decompositions of Non-manifold Objects 

      Floriani, L. De; Hui, A. (The Eurographics Association, 2004)
      We address the problem of updating non-manifold mixed-dimensional objects, described by three-dimensional simplicial complexes embedded in 3D Euclidean space. We consider two local update operations, edge collapse and ...
    • 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 ...
