✦ Synopsis

and Exhibition was held in the land of smiles, Thailand, May 24-28. Topics for paper presentation covered a large spectrum ranging from numerical control, through design for manufacturing, to applications in biology and jewelry design. Based on the recommendations of the Advisory Board, two special issues were selected out of the 163 submitted papers. This special issue covers the modeling aspects of CAD whereas the second one is devoted to issues of manufacturing, product modeling, CAD and CAE integration and collaborative design.

We start this issue with visibility maps and spherical algorithms by Jong-Sung Ha of Woosuk University. The methods presented are useful in optimal work piece setup and part orientation. An algorithm is presented to find the approximating centroids for the maximum intersection of spherical polygons.

A B-spline curve approximation method to dense and noisy data is presented by Weishi Li, Shuhong Xu, Gang Zhao and Li Ping Goh. The algorithm smoothes the discrete curvature by placing knots adaptively to satisfy a heuristic rule.
