Semi-Regular 4-8 Refinement and Box Spline Surfaces
نویسنده
چکیده
In this paper we introduce a new mesh refinement method for subdivision surfaces. It generates a semiregular 4-direction hierarchical structure from control meshes representing 2D manifolds of arbitrary topology. The main advantage of this structure is that it allows the extraction of conforming variable-resolution meshes based on spatially varying adaptation functions. We also present a smoothing method designed to work in conjunction with our semi-regular refinement. It produces generalized four direction Box spline surfaces of class C . Together the refinement and smoothing operators result in a subdivision scheme that is very effective in multiresolution applications.

4-8 Subdivision
In this paper we introduce 4–8 subdivision, a new scheme that generalizes the fourdirectional box spline of class C to surfaces of arbitrary topological type. The crucial advantage of the proposed scheme is that it uses bisection refinement as an elementary refinement operation, rather than more commonly used face or vertex splits. In the uniform case, bisection refinement results in doubling, ...
متن کاملUsing Semi-Regular 4-8 Meshes for Subdivision Surfaces
Semi-regular 4–8 meshes are refinable triangulated quadrangulations. They provide a powerful hierarchical structure for multiresolution applications. In this paper, we show how to decompose the DooSabin and Catmull-Clark subdivision schemes using 4–8 refinement. The proposed technique makes it possible to use these classical subdivision surfaces with semi-regular 4–8 meshes. Additional

T-meshes are formed by a set of horizontal line segments and a set of vertical line segments, where T-junctions are allowed. See Figure 1 for examples. Traditional tensor-product B-spline functions, which are a basic tool in the design of freeform surfaces, are defined over special T-meshes, where no T-junctions appear. B-spline surfaces have the drawback that arises from the mathematical prope...

We introduce curvature continuous regular free-form surfaces with triangular control nets. These surfaces are composed of quartic box spline surfaces and are piecewise polynomial multisided patches of total degree 8 which minimize some energy integral. The B ezier nets can be computed eeciently form the spline control net by some xed masks, i.e. matrix multiplications. k-free-form surfaces need...
