Shape Similarity Measurement Using Ray Distances for Mass Customization
(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 ...
Tolerance Envelopes of Planar Parametric Part Models
(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 ...
Automatic Building of Structured Geological Models
(The Eurographics Association, 2004)
The present article proposes a method to signi cantly improve the construction and updating of 3D geological models used for oil and gas exploration. The proposed method takes advantage of the speci c structures which ...
B-rep SE: Simplicially Enhanced Boundary Representation
(The Eurographics Association, 2004)
Boundary representation (B-rep) is a popular representation scheme for mechanical objects due to its ability to accurately represent piecewise smooth surfaces bounding solids. However, non-trivial topology and geometry of ...
Physics-based Modelling and Simulation of Functional Cloth for Virtual Prototyping Applications
(The Eurographics Association, 2004)
A CAD-oriented system is proposed for the design of complex-shaped functional cloth, provided with a physics-based modelling core for simulation and virtual prototyping tasks. Textiles are physically modelled as particle ...
3D Discrete Skeleton Generation by Wave Propagation on PR-Octree for Finite Element Mesh Sizing
(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 ...
A Framework for Multiresolution Adaptive Solid Objects
(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 ...
Fast Continuous Collision Detection for Articulated Models
(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 Condition for Isotopic Approximation
(The Eurographics Association, 2004)
In this paper, we give a very simple and purely topological condition for two surfaces to be isotopic. This work is motivated by the problem of surface approximation. Applications to implicit surfaces are given, as well ...
Making the Most of Using Depth Reasoning to Label Line Drawings of Engineering Objects
(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 ...
