Hybrid B Ezier Patches on Sphere-like Surfaces
نویسندگان
چکیده
We develop a method for interpolating scattered data on sphere-like surfaces based on a local triangular patch which is constructed from a blend of certain spherical Bernstein-B ezier polynomials introduced recently by Alfeld, Neamtu & Schumaker 2]. The method produces a C 1 interpolant which matches values and derivatives, and is a natural analog of a planar method of Foley & Opitz 6] and Goodman & Said 7]. We also show how the same approach can be used to construct a C 2 quintic hybrid patch matching second derivative information as an analog of a planar method of Chang & Said 5].

Bernstein-Bézier polynomials on spheres and sphere-like surfaces
In this paper we discuss a natural way to deene barycentric coordinates on general sphere-like surfaces. This leads to a theory of Bernstein-B ezier polynomials which parallels the familiar planar case. Our constructions are based on a study of homogeneous polynomials on trihedra in IR 3. The special case of Bernstein-B ezier polynomials on a sphere is considered in detail.
متن کاملA Bound on the Implicit Degree of Polygonal B ezier Surfaces
Recent work has shown that the triangular rational B ezier surface representation can be used to create polygonal surface patches. The key to the construction is the judicious use of zero weights in creating the surface parameterization. These zero weights introduce base points into the resulting rational parameterizations. Base points also lower the degree of the implicit representation of the...
متن کامل000 Society for Industrial and Applied Mathematics Dimension and Local Bases of Homogeneous Spline Spaces*
Recently, we have introduced spaces of splines deened on triangulations lying on the sphere or on sphere-like surfaces. These spaces arose out of a new kind of Bernstein-B ezier theory on such surfaces. The purpose of this paper is to contribute to the development of a constructive theory for such spline spaces analogous to the well-known theory of polynomial splines on planar triangula-tions. ...

متن کاملEecient Rendering of Trimmed Nurbs Surfaces
We present an algorithm for interactive display of trimmed NURBS surfaces. The algorithm converts the NURBS surfaces to B ezier surfaces and NURBS trimming curves into B ezier curves. It tessellates each trimmed B ezier surface into triangles and renders them using the triangle rendering capabilities common in current graphics systems. It makes use of tight bounds for uniform tessel-lation of B...
