Reverse Subdivision Multiresolution for Polygonal Silhouette Error Correction
نویسندگان
چکیده
This paper presents a method for automatic removal of artifacts that appear in silhouettes extracted from polygonal meshes due to the discrete nature of meshes and numerical instabilities. The approach works in object space on curves made by chaining silhouette edges and uses multiresolution techniques based on a reverse subdivision method. These artifact-free curves are then rendered in object-space as weighted 3D triangle-ribbon strips.

Polygonal silhouette error correction: a reverse subdivision approach
A method for automatic removal of artifacts and errors that can appear in silhouettes extracted from polygonal meshes is presented and evaluated. These errors typically appear in polygonal silhouettes due to the discrete nature of meshes and numerical instabilities. The approach presented works in object space on silhouette curves made by chaining together silhouette edges and uses multiresolut...
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...
متن کاملCapturing and Re-Using Artistic Styles with Reverse Subdivision-Based Multiresolution Methods
We describe a multiresolution method for rendering curves that is based on exact reproduction of artistic silhouettes and line hand-gesture styles. Using analysis based on reverse subdivision, we extract examples from both scanned images of line-drawn artwork and interactively-sketched input and apply these styles to the arbitrary strokes of new illustrations. Our algorithms work directly with ...
متن کاملNon-linear Subdivision of Univariate Signals and Discrete Surfaces
During the last 20 years, the joint expansion of computing power, computer graphics, networking capabilities and multiresolution analysis have stimulated several research domains, and developed the need for new types of data such as 3D models, i.e. discrete surfaces. In the intersection between multiresolution analysis and computer graphics, subdivision methods, i.e. iterative refinement proced...
متن کاملTruly selective polygonal mesh hierarchies with error control
In this work a new multi-resolution model is proposed for polygonal meshes. It is based on the dual edge collapse, which performs face clustering instead of vertex clustering. The new hierarchical mesh representation combines a truly selective refinement scheme with a strict control of the two-sided Hausdorff distance. The proposed approach allows to build hierarchical meshes directly over non ...
