Advantages of the Boundary Representation
(i) This format gives efficient picture generation and easy access to other geometric information.
(ii) The changes produced by most editing operations (e.g. tilting one face through a given angle) cause local effects not global ones.
(iii) It is comparatively easy to define a face lying on a surface defined parametrically.
(iv) It is easy to create objects by "sweeping", i.e. a complex two-dimensional profile may be translated or rotated about an axis to give a shape in three-dimensions.
(v) The main advantage of b-rep is that it is very appropriate to construct solid models of unusual shapes that are difficult to build using primitives, e.g., aircraft fuselage and automobile body styling. It is also relatively simple to convert a b-rep model into a wire-frame model.
