چکیده

2. MAIN RESULTS In this paper, subdivision methods for rectangular Bézier A rectangular Bézier surface of degree n 3 m can be surfaces are generalized to subdivide a rectangular Bézier surface patch of degree n 3 m into two rectangular Bézier surrepresented by face patches of degree n 3 (m 1 n), while the parameter domain of the Bézier surface is decomposed into two trapezoids. As an application, a conversion from rectangular Bézier surP(u, v) 5 On i50 Om j50 Pij B i (u)B j (v), 0 # u, v # 1, faces to triangular Bézier surfaces is presented.  1996 Academic

Degree Reduction of Disk Wang-Bézier Type Generalized Ball Curves

A disk Wang-Bézier type generalized Ball curve is a Wang-Bézier type generalized Ball curve whose control points are disks in a plane. It can be viewed as a parametric curve with error tolerances. In this paper, we discuss the problem of degree reduction of disk Wang-Bézier type generalized Ball curve, that is, bounding disk Wang-Bézier type generalized Ball curves with lower degree disk Wa...

Direct Ray Tracing of Full-Featured Subdivision Surfaces with Bézier Clipping

We present a novel, direct ray-tracing method for rendering Catmull-Clark subdivision surfaces. Our method resolves an intersection with Bézier patches without performing of polygon tessellation as done in most traditional renderers. It supports the full set of RenderMan and OpenSubdiv subdivision surface features, including hierarchical edits, creases, semi-sharp creases, corners, the chaikin ...

Mean Value Bézier Surfaces

Bézier surfaces are an important design tool in Computer Aided Design. They are parameterized surfaces where the parameterization can be represented as a homogeneous polynomial in barycentric coordinates. Usually, Wachspress coordinates are used to obtain tensor product Bézier surfaces over rectangular domains. Recently, Floater introduced mean value coordinates as an alternative to Wachspress ...

On convex Bézier triangles

— Goodman [8] showed that uniform subdivision of triangular Bézier nets preserves convexity. Hère, a very short proofofthis f act is given which applies even to box spline surfaces and degree élévation instead of subdivision. Secondiy, it is shown that every Bézier net of a quadratic convex Bézier triangle can be subdivided such that the net becomes convex.
