The Faceter Component (FCT) generates and controls approximate polygonal representations. The polygon approximations are used in all active and static rendering, in clearance analysis, and in operations where approximations are acceptable to simplify calculations. You supply a facet_options object to the Faceter that specifies how the polygons should be generated. The ACIS Faceter supports only view-independent faceting.
Faceting generates approximate polygonal representations for the faces of entities while maintaining edge consistency between adjacent faces. Face faceting is performed by subdividing the face in parameter space with a grid whose increments are determined through the facet_options object. This specifies the accuracy of the faceted representation, and also controls the details of how triangulation is performed. The faceted representation of a face is also called a mesh.
Faceting is used by all active and static renderers. The facet options have a significant effect on the rendering process: the tighter the facets, the smoother the rendered surface is. However, the tighter the facets, the slower the rendering process becomes. On the other hand, the looser the facets, the faster the rendering process becomes, but the rendered surface is rougher. Refer to Facet Options for more details.
Facet information is not stored in saved files. However, facets can be output through Mesh Managers to an application-determined data structure, which the application can manage as it sees fit.
