1106 Paper craft design of objects that includes free form surfaces based on lines of curvature

Abstract

We introduce a method to generate developed paper craft patterns of free-form surfaces based on lines of curvature. Objects that consist of free-form surfaces can be developed onto a plane by expanding the surfaces along the lines of curvature. If we remove all the expanded areas, paper crafts can be constructed by connecting the corresponding edges of the removed areas. Several real paper crafts are provided to demonstrate the effectiveness of the proposed method.
