Abstract

Disclosed is a system for generating rough quadrilateral meshes from finer triangular meshes. The quadrilateral meshes can be used for generating parametric curved surfaces that represent the geometry of the input triangular meshes (see Figure 1). This system first divides the region of a triangular elements into belt-like subregions (see Figure 2(a)(b)), and then divides each subregion into quadrilateral elements (see Figure 2(c)(d)). Figure 1. An example of the input triangular mesh, the output quadrilateral mesh, and the parametric curved surface. 1
