Faceting is an operation that generates approximate polygonal representations for the faces of entities. Edge consistency is maintained between adjacent faces. Face faceting is performed by subdividing the face in parameter space with a grid whose increments are determined through
refinements. Refinements specify the accuracy of the faceted representation. Refinements also control how triangulation is performed and whether smoothing is used to improve the aspect ratios of triangles. The faceted representation of a face is also called a
mesh. Faceted representations are used in rendering, in clearance analysis, and in operations where an approximation is acceptable in order to simplify calculations. See also
refinement.
