Loop Subdivision Surface Fitting by Geometric Algorithms
This paper describes a method to approximate point sets by Loop subdivision surfaces based on geometric algorithms. We assume that the data points are given in triangular mesh of arbitrary topological type. The initial control mesh of the Loop subdivision surface is obtained by simplifying the input triangular mesh using QEM algorithm. Our algorithm iteratively updates the control mesh in a glo...
متن کاملIncremental Adaptive Loop Subdivision
In this paper, a new adaptive Loop subdivision algorithm is introduced. Adaptive subdivision refines specific areas of a model according to user or application needs. Our algorithm extends the specified area such that when it is adaptively subdivided, it produces a smooth surface with visually pleasing connectivity. As adaptive subdivision is repeated, subdivision depth changes gradually from o...
متن کاملFitting Sharp Features with Loop Subdivision Surfaces
Various methods have been proposed for fitting subdivision surfaces to different forms of shape data (e.g., dense meshes or point clouds), but none of these methods effectively deals with shapes with sharp features, that is, creases, darts and corners. We present an effective method for fitting a Loop subdivision surface to a dense triangle mesh with sharp features. Our contribution is a new ex...
متن کاملInterpolation by Loop ’ S Subdivision Functions
For the problem of constructing smooth functions over arbitrary surfaces from discrete data, we propose to use Loop’s subdivision functions as the interpolants. Results on the existence, uniqueness and error bound of the interpolants are established. An efficient progressive computation algorithm for the interpolants is also presented. Mathematics subject classification:
متن کاملREVERSE LOOP SUBDIVISION FOR GEOMETRY AND TEXTURES
Reverse subdivision aims at constructing a coarser representation of an object given by a fine polygon mesh. In this paper, we first derive a mask for reverse Loop subdivision that can be applied to both regular and extraordinary vertices. The mask is parameterized, and thus can also be used in reversing variants of Loop subdivision, such as those proposed by Warren and Litke. We apply this mas...
