4.1.15 geometrically_bounded_surface_model (G8)

This unit of functionality provides the capability to represent geometry as a surface model that is geometrically bounded.

This UoF provides basic geometric constructs, such as three-dimensional points, curves, and surfaces. It includes elementary and sculptured surfaces as well as composite surfaces. Points and curves can be represented in the parameter space of curves or surfaces, respectively, by objects such as point on curve and parametric curve. The replication of the geometric objects is not included in this UoF.

The basic geometric constructs are used for the definition of complex geometric objects, i.e., geometrically bounded surfaces without connectivity. They are also used within the connected_surface_model UoF (G3) and b_rep_model UoF (G5) for the definition of topologically bounded surfaces with topological connections.

NOTE This UoF does not contain any topological information. Therefore, the geometrically bounded surfaces cannot be connected by topology.

The following application objects are used by the geometrically_bounded_surface_model UoF:
