Offsetting operations in solid modelling

Abstract: The range of operations on solids supported by current geometric mod elling systems is very limited. Typically, solids represented in a modeller can be transformed by rigid motions and combined by Boolean operations. This paper introduces another family of transformations, called solid offsetting, which map solids into solids.Offset solids are expanded or contracted versions of an original object. Offsetting operations are potentially useful for tolerance analysis, clearance testing, design-rule checking in VL… Show more

“…Several specific GOG systems have been studied by Rossignac: offset and blending nodes in CSG [Rossignac86a], constraints in CSG [Rossignac86b], and operations as general procedures [Rossignac89]. A GOG with constraints between coordinate systems and an underlying procedural programming language was described in [Emmerik90].…”
