Three-dimensional object metamorphosis through energy minimization

ÐThis paper presents a technique for smoothly blending some categories of three-dimensional polygonal objects. Polygon blending is usually considered a two-part process: generating vertex correspondences and interpolating between corresponding vertices to create the intermediate polygons. This paper considers the problem of automatic vertex correspondence determination. The proposed algorithm is based on the work of Sederberg and Greenwood [Computer Graphics 26(2), 25±34, 1992]. The resulting solution tends to associate regions of the two objects which look alike. # 1998 Elsevier Science Ltd. All rights reserved.
