ABSTRACT:
An improved Direct Surface Manipulation (DSM) method is disclosed which incorporates a global surface reparametrization scheme for the purposes of extending the DSM method to applications involving multiple surfaces and for reducing the geometric effect of parametric space distortions on the features. This method reparametrizes multiple surface patches with a shared two-dimensional space defined in the object space of the model. The result is a geometrically consistent mesh, called a super-mesh, that serves as a global, uniform parametric space for topologically-disconnected, geometrically-disproportional surface patches. Spherical projection is employed to perform the patch reparametrization. This allows the creation of DSM features on multiple surface patches with improved shape quality.
