View-dependent Transmission of Three-dimensional Mesh Models Using Hierarchical Partitioning
نویسندگان
چکیده
In this paper, we propose a new scheme for sending three-dimensional (3-D) mesh models. In order to make a viewdependent representation of 3-D mesh models, we combine sequential and progressive mesh transmission techniques. After we partition a 3-D mesh model into a hierarchical tree, we determine the amount of information for each submesh. Then, we can send the 3-D model information by view-dependent selection with mesh merging and splitting operations. Experimental results have demonstrated that the proposed scheme can send mesh information adaptively through mesh merging and splitting operations and provides good visual quality in a limited bandwidth channel.

متن کاملQuadtree and Octree Grid Generation
Engineering analysis often involves the accurate numerical solution of boundary value problems in discrete form. Hierarchical quadtree (or octree) grid generation offers an efficient method for the spatial discretisation of arbitrary-shaped two- (or three-) dimensional domains. It consists of recursive algebraic splitting of sub-domains into quadrants (or cubes), leading to an ordered hierarchi...
متن کاملSequential Mesh Coding Using Wave Partitioning
Recently, various three-dimensional(3-D) mesh coding schemes have been proposed to improve compression efficiency or error resilience. However, we need to consider both coding efficiency and error resilience when we send 3-D mesh data over bandwidth-limited transmission channels. In this paper, we propose a sequential mesh coding algorithm using the vertex pedigree based on the wave partitionin...

متن کاملA new conforming mesh generator for three-dimensional discrete fracture networks
Nowadays, numerical modelings play a key role in analyzing hydraulic problems in fractured rock media. The discrete fracture network model is one of the most used numerical models to simulate the geometrical structure of a rock-mass. In such media, discontinuities are considered as discrete paths for fluid flow through the rock-mass while its matrix is assumed impermeable. There are two main pa...
