Lossy 3D Mesh Compression using Loop Scheme

چکیده
Subdivision surfaces are finding their way into many Computer Aided Design and Animation packages. Popular choices include Loop, Catmull-Clark, Doo-Sabin etc. Subdivision surfaces have many design advantages over traditional use of Non Uniform Rational B-Splines (NURBs). 3D mesh compression has become necessary for transferring and browsing 3D objects over the internet. MPEG-4 has included encoding capability for 3D polygonal meshes. Level of details (LOD), progressive transmission, and 3D streaming are possible applications of the mesh compression. Our paper looks at developing one such method for Loop surfaces. Our method can handle any arbitrarily topological non-boundary/boundary objects of any genus. The paper shows the process as well as some results, which are promising and therefore can be used as a lossy compression scheme and a surface reconstruction method.

Also, in recent years 3D mesh compression has become necessary for transferring and browsing 3D objects over the internet. This paper explore...
متن کاملGeometric and Topological Lossy Compression of Dense Range Images
This paper presents a technique for lossy compression of dense range images. Two separate compression schemes are applied. The first scheme (geometric compression) reduces redundant geometric information by generating an adaptive 3D triangular mesh that approximates the shapes present in the original range image. Geometric compression is used for obtaining an efficient representation of the ran...
متن کاملReverse Engineering Using a Subdivision Surface Scheme
Subdivision surfaces are finding their way into many Computer Aided Design and Animation packages. Popular choices include Loop, Catmull-Clark, Doo-Sabin etc. Subdivision surfaces have many design advantages over traditional use of NURBs. NURB surfaces always are problematic when multiple patches meet. Reverse engineering (RE) is associated with the idea of scanning physical objects and represe...
متن کاملSubdivision surface fitting for efficient compression and coding of 3D models
In this paper we present a new framework, based on subdivision surface fitting, for high rate compression and coding of 3D models. Our algorithm fits the input 3D model, represented by a polygonal mesh, with a piecewise smooth subdivision surface represented by a coarse control polyhedron. Our fitting scheme, particularly suited for meshes issued from mechanical or CAD parts, aims at getting cl...
متن کاملImpact of MPEG-4 3D mesh coding on watermarking algorithms for polygonal 3D meshes
The MPEG-4 multimedia standard addresses the scene-based composition of audiovisual objects. Natural and synthetic multimedia content can be mixed and transmitted over narrow and broadband communication channels. Synthetic natural hybrid coding (SNHC) within MPEG-4 provides tools for 3D mesh coding (3DMC). We investigate the robustness of two different 3D watermarking algorithms for polygonal m...
