Abstract

A planar parameterization of 3D surfaces is useful for many applications, The applicability of the parameterization depends on how well it preserves the surface geometry (angles, distances, and areas). For most surface meshes there is no parameterization which preserves the geometry exactly. The distortion usually increases with the rise in surface complexity. For highly complicated surfaces the distortion can become so strong as to make the parameterization unusable for application's purposes. A solution is to partition the surface or introduce cuts in a way which will reduce the distortion. This article presents a new method for cutting seams in 3D mesh surfaces. The addition of seams reduces the surface complexity and hence reduces the metric distortion produced by the parameterization. Seams often introduce additional constraints on the application for which the parameterization is used, hence their length should be minimal. The presented method minimizes the seam length while reducing the parameterization distortion to acceptable level.
