<p>A method and system for computer aided design (CAD) for designing geometric objects (30, 34). The present invention interpolates and/or blends (B1(u, v), B2(u, v)) between geometric objects (62) sufficiently fast so that real-time deformation of such objects occurs while deformation data is being input. Thus, a user designing obtains immediate feedback to input modifications without separately entering a command for performing deformation. The present invention utilizes novel computational techniques for blending between geometric objects, wherein weighted sums of points on the geometric objects are used in deriving a new blended geometric object. The present invention is particularly useful for designing the shape of surfaces (S1, S2) and various design domains; additionally, providing efficient animation via repeatly modifying surfaces of an animated object.</p> |
