| Abstract: | The principles and methods for deriving an envelope cure are introduced. Based on these, the equations of different curves as well as their envelope curve equations are studied comprehensively. It is emphasized on the derivation of the envelop curves models of line manifold, circle manifold, conic manifold and ellipse manifold. By using those models, a package of figure module is developed, and furthermore, those principles and methods are proved as true. |
