چکیده

Due to their simplicity triangle meshes are often used to represent geometric surfaces. Their main drawback is the large number of triangles that are required to represent a smooth surface. This problem has been addressed by a large number of mesh simplification algorithms which reduce the number of triangles and approximate the initial mesh. Hierarchical triangle mesh representations provide access to a triangle mesh at a desired resolution, without omitting any information. In this talk we present an infrastructure for discrete geometry processing, including algorithms for 3D reconstruction, curvature computation, reverse engineering, mesh reduction, interactive multiresolution modeling and progressive transmission of arbitrary unstructured triangle meshes.

Recent Advances in Multiresolution Analysis of 3D Meshes and their Applications

3D meshes are widely used in computer graphics applications for approximating 3D models. When representing complex shapes in raw data format, meshes consume a large amount of space. Applications calling for compact and fast processing of large 3D meshes have motivated a multitude of algorithms developped to process these datasets efficiently. The concept of multiresolution analysis proposes an ...

An efficient subdivision inversion for wavemesh-based progressive compression of 3D triangle meshes

Wavemesh is a powerful scheme for 3D triangular mesh processing. In sharp contrast with other approaches using wavelets for mesh compression which apply only to meshes having subdivision connectivity, Wavemesh can simplify, approximate, and compress meshes even if they do not respect this constraint, with unmatched results for progressive lossless compression when compared to other approaches. ...

Simplification of Fan-Meshes Models for Fast Rendering of Large 3D Point-Sampled Scenes

Fan-Meshes (FM) are a kind of geometrical primitives for generating 3D model or scene descriptions that are able to preserve both local geometrical details and topological structures. In this paper, we propose an efficient simplification algorithm for the FM models to achieve fast post-processing and rendering of large models or scenes. Given a global error tolerance for the surface approximati...

Compression of parametric surfaces for efficient 3D model coding

In the field of compression, the type of 3D models traditionally considered is that of polygonal meshes, for which several efficient compression techniques have been proposed in the recent years. Nowadays, an increasing proportion of 3D models are created by a synthesis or modeling process, instead of captured from the real world. Such models are most often given as parametric surfaces, which h...

Direct (Re)Meshing for Efficient Surface Processing

Many geometry processing techniques exploit the connection between shape and connectivity in triangle meshes to enable advanced processing of the data. These techniques face the challenge that triangle meshes, whether generated by a modeling tool or by 3D scanning, typically contain low quality triangles. The process of constructing good meshes out of sub-optimal ones is termed surface remeshin...
