Title Trimmed surfaces
Date 1991-03
Description Parametric surfaces and set operations have both become known as a valuable to the geometric modeling of rigid solids. Parametric surfaces give a geometric modeller a wider range, providing for the representation of parts with sculptured surfaces. Set operations of union, differences or intersections on objects bounded by parametric surfaces make the task of creating some objects easier than it might be by direct modelling. These two tools taken together, however, create a problem because a set operation on an object bounded by rectangular parametric surfaces rarely results in an object bounded solely by whole rectangular parametric surfaces. Pieces of some of the operand parametric surfaces will be present in the result of the operation, and these pieces are called trimmed surfaces. This thesis proposes a representation for trimmed surfaces which may be used toward solution of the closure problem. Algorithms will be presented which display solids bounded by trimmed surfaces.
