    • An Effective Condition for Sampling Surfaces with Guarantees 

      Boissonnat, J. D.; Oudot, S. (The Eurographics Association, 2004)
      The notion of e-sample, as introduced by Amenta and Bern, has proven to be a key concept in the theory of sampled surfaces. Of particular interest is the fact that, if E is an e-sample of a smooth surface S for a suf ciently ...

    • Efficient and Robust Computation of an Approximated Medial Axis 

      Yang, Y.; Brock, O.; Moll, R. N. (The Eurographics Association, 2004)
      The medial axis can be viewed as a compact representation for an arbitrary model; it is an essential geometric structure in many applications. A number of practical algorithms for its computation have been aimed at speeding ...

    • Efficient Processing of 3D Scanned Models 

      Scopigno, R. (The Eurographics Association, 2004)
      The construction of detailed and accurate 3D models is made easier by the increasing diffusion of automatic sampling devices (often called 3D scanners). These allow to build digital models of real 3D objects in a cost- and ...

    • 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 ...

    • Fast Continuous Collision Detection for Articulated Models 

      Redon, S.; Lin, M. C.; Manocha, D. (The Eurographics Association, 2004)
      We present a novel algorithm to perform continuous collision detection for articulated models. Given two discrete configurations of the links of an articulated model, we use an ''arbitrary in-between motion'' to interpolate ...

    • A Framework for Multiresolution Adaptive Solid Objects 

      Chang, Y.- S.; Qin, H. (The Eurographics Association, 2004)
      Despite the growing interest in subdivision surfaces within the computer graphics and geometric processing communities, subdivision approaches have been receiving much less attention in solid modeling. This paper presents ...

    • From Computer Geometry to Manufacturing Algorithms 

      Cohen, E. (The Eurographics Association, 2004)
      Abstractly, machining a shape is rather a simple task, that is, one is merely asked to subtractively metamorphose a superset of stock material into the ultimate shape of a given geometric model. In practice, however, there ...

    • Frontmatter Solid Modeling 2014 

      Gershon Elber and Nicholas Patrikalakis and Pere Brunet (The Eurographics Association, 2004)
      Table of Contents and Preface, Committees, Cover

    • 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 ...

    • History Based Reactive Objects for Immersive CAD 

      Convard, T.; Bourdot, P. (The Eurographics Association, 2004)
      Virtual Environments (VE) allow direct 3D interaction, better perception of shapes and a feel of immersion, properties that are highly desirable for design tasks. Traditional CAD software extensively use WIMP interfaces ...

    • 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 ...

    • Implicit Curve and Surface Design Using Smooth Unit Step Functions 

      Li, Q. (The Eurographics Association, 2004)
      This paper presents an implicit curve and surface design technique that uses smooth unit step functions. With the proposed method, an implicit curve or surface can be generated by inputting a sequence of points together ...

    • Integrated Feature-Based and Geometric CAD Data Exchange 

      Spitz, S. N.; Rappoport, A. (The Eurographics Association, 2004)
      Data exchange between CAD systems is an extremely important solid modeling concept, fundamental both for the theory of the field and for its practical applications. The two main data exchange (DE) paradigms are geometric ...

    • Making the Most of Using Depth Reasoning to Label Line Drawings of Engineering Objects 

      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 ...

    • Medial Axis Extraction and Shape Manipulation of Solid Objects Using Parabolic PDEs 

      Du, H.; Qin, H. (The Eurographics Association, 2004)
      Shape skeletonization (i.e., medial axis extraction) is powerful in many visual computing applications, such as pattern recognition, object segmentation, registration, and animation. This is because medial axis (or skeleton) ...

    • Medial-Axis Based Solid Representation 

      Shaham, A.; Shamir, A.; Cohen-Or, D. (The Eurographics Association, 2004)
      The medial axis (MA) of an object and medial axis transform (MAT) have many applications in solid modeling, computer graphics and other areas. Exact computation of MA is complex and various medial axis approximation ...

    • Multiresolution Heterogeneous Solid Modeling and Visualization Using Trivariate Simplex Splines

      This paper presents a new and powerful heterogeneous solid modeling paradigm for representing, modeling, and rendering of multi-dimensional, physical attributes across any volumetric objects. The modeled solid can be of ...

    • Optimization Techniques for Approximation with Subdivision Surfaces 

      Marinov, M.; Kobbelt, L. (The Eurographics Association, 2004)
