WebAny tessellation (for example, a polygonization) of a manifold surface will produce edges that are of degree two; that is, all edges are shared by exactly two faces. Tessellations of non-manifold surfaces produce edges of degree 1, 2, 3, or more. A polygonized, bounded implicit surface has edges of degree two, whereas many WebPrevious work on implicit surfaces has almost exclusively focused on homogeneously 2-dimensional surfaces, regardless of whether they are manifold or not. Consequently, current geometric and graphical systems, and even commercial mathematical software packages, cannot generate non-homogeneous implicit surfaces such as, for example, the Steiner …
