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 WebThe implicit field is polygonized by the algorithm based on the marching cubes algorithm, which is extended to treat discontinuous fields correctly.

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 … WebPolygonization of Non-Manifold Implicit Surfaces Jules Bloomenthal and Keith Ferguson Department of Computer Science The University of Calgary Abstract Any tessellation of a manifold surface, such as the polygonization of a finite (i.e., bounded) implicit surface, produces edges that are of degree two; that is, all edges are shared by exactly two faces.

WebA method is presented to broaden implicit surface modeling. The implicit surfaces usually employed in computer graphics are two dimensional manifolds because they are defined by real-valued functions that impose a binary regionalization of space (i.e., an inside and an outside). When tiled, these surfaces yield edges of degree two.
