Non-Local Topological Clean-Up
A new approach to topological clean-up of 2D meshes is presented. Instead of searching for patterns in a mesh and replacing them as in other methods, the proposed method replaces a region in a mesh only according to the boundary of that region. This simplifies the classification of the different cases, and allows mesh modification over greater regions in the mesh. An algorithm for quadrilateral...
متن کاملA Scale-up Design Procedure for Rotating Biological Contactors
A scale-up design procedure, based on a new physical mass transfer (PMT) model, whichdescribes the performance, for aerobic rotating biological contactors (RBC’s) is developed. This scale-up procedure can be used to determine the disc surface area needed to prevent an oxygen limitation or to obtain a specific degree of treatment. In contrast to the empirical, and most previous RBC performance m...
متن کاملA General Algorithm for Triangular Meshes Simplification
This article introduces the algorithm for simplification of 2D and 3D triangular meshes. The algorithm evaluates and removes vertices. A hash table is used to speed up the process of selecting the appropriate vertex for its removal. Therefore, this part of the algorithm is executed in constant time O(1). In spite of simplification, triangular mesh models still keep majority of their own essenti...
متن کاملA Slicing Algorithm for Triangular Meshes
In this paper a slicing procedure for extracting geometric informations about triangular meshes is presented. In manufacturing sculptured surfaces are often represented by triangular meshes. Errors in the mesh as gaps, holes and invalid triangles lead in planar sections to defective contour lines used as tool path in milling or rapid prototyping. The slicing procedure works on a polyhedral data...
متن کاملGeometric Snakes for Triangular Meshes
Feature detection is important in various mesh processing techniques, such as mesh editing, mesh morphing, mesh compression, and mesh signal processing. In spite of much research in computer vision, automatic feature detection even for images still remains a difficult problem. To avoid this difficulty, semi-automatic or interactive techniques for image feature detection have been investigated. ...
