Matched part-pair blending for 3D shape creation

ABSTRACT

We present an efficient and practical 3D shape creation algorithm based on the part matching and blending. Given two existing 3D shapes, part correspondences are found firstly by part matching, then two effective methods are investigated to blend the matched part-pair. The rapid one, which corresponds facets and vertices between matched part-pair, blends the coordinates of the corresponding vertices and generates new vertices to create the new part. And the elaborate one, which parameterizes the matched part-pair, combines their meshes and interpolates the vertices for part variation. Finally, all blended parts are rearranged by means of the topological relations in the given shapes to produce the integrated variations. Experimental results indicate that this algorithm is capable of implementing continuous and multipath shape variation as well as creating novel and plausible 3D shapes. This technique could allow for more efficient shape blending in the product innovation design and the animation industry.
