Editorial

Many problems of practical importance require meshing, the subdivision of a given geometric domain into a set of simpler elements such as !ine segments, convex polygons and convex polyhedrons. Over the past few decades many meshing problems have emerged in various computer appli- cations, along with a corresponding collection of solution techniques. These applications include engineering analy- sis, computer graphics, geometric modeling, and computer vision. In these applications, mesh representations are often necessary for two reasons: (1) some fundamental numerical methods, such as the finite element method or the boundary element method, inherently require a meshed geometry; and (2) more robust and efficient geometric algorithms are avail- able for a meshed geometry.

For this special issue of Computer-Aided Design, of 40 peer-reviewed papers presented at the 8th International Meshing Roundtable [2], six papers were selected for publi- cation here based on the initial reviews, recommendations from session chairs, and discussions among the organizing committee members. All the papers deal with theoretical and/or computational aspects of automatic mesh generation; the first four papers discuss topics related to the meshing of a three-dimensional domain, followed by a paper on surface meshing and a paper on two-dimensional meshing. We thank the authors for revising and extending their original papers for this special issue.

Finally, it should be mentioned that the latest roundtable, the 9th International Meshing Roundtable, was held successfully in New Orleans, Louisiana, USA, 2-5 October 2000. Detailed information can be found at the roundtable web site [3].
