✦ Synopsis

Form features, like protrusions or depressions on a/ace, through-holes or handles, can be extracted /rom a relational boundary model of a solid object, called the 'symmetric boundary graph" by loop identification and connected component labelling. The result is a decomposition ot the object boundary into volumetric components describing features, which is represented as a directed labelled multigraph, called the "object decomposition graph'. Based on such a model, issues such as representation uniqueness and matching4 of object descriptions are discussed.

Progressive mesh representation and generation have become one of the most important issues in network-based computer graphics. However, current researches are mostly focused on triangular mesh models. On the other hand, solid models are widely used in industry and are applied to advanced applicatio

Optical scatterometry has established itself as one of the mainly applied methods for CD metrology besides CD-SEM during the recent years. However, grating imperfections such as line edge roughness have been largely neglected in scatterometry models so far. Since imperfections of the perfect periodi
