Multiresolution Modelling of Polygonal Surface Meshes Using Triangle Fans
نویسندگان
چکیده
Multiresolution modelling of polygonal surface meshes has been presented as a solution for the interactive visualisation of scenes formed by hundreds of thousands of polygons. On the other hand, it has been shown that representing surfaces using sets of triangle strips or fans greatly reduces visualisation time and provides an important memory savings. In this paper we present a new method to model polygonal surface meshes. Like the previously explained Multiresolution Ordered Meshes (MOM), this method permits the efficient management of an ample range of approximations of the given model. Furthermore, this method utilises the triangle fan as its basic representation primitive. Experiments realised with data sets of varying complexity demonstrate reduced storage space requirements, while retaining the advantages of MOMs.

Multiresolution Modelling Using Connectivity Information
Triangles meshes are the most popular standard model used to represent polygonal surfaces in Computer Graphics. Drawing these meshes as a set of independent triangles involves sending a vast amount of information to the graphic engine. The use of primitives such as triangle fans and strips, which make use of the connectivity information between the triangles in the mesh, dramatically reduces th...
متن کاملReverse Subdivision Multiresolution for Polygonal Silhouette Error Correction
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...

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...

Multiresolution modelling techniques are important to cope with the increasingly complex polygonal models available today such as high-resolution isosurfaces, large terrains, and complex digitized shapes 21. Large triangle meshes are difficult to render at interactive frame rates due to the large number of vertices to be processed by the graphics hardware. Level-of-detail (LOD) based visualizat...
متن کاملA Shrink Wrapping Approach to Remeshing Polygonal Surfaces
Due to their simplicity and flexibility, polygonal meshes are about to become the standard representation for surface geometry in computer graphics applications. Some algorithms in the context of multiresolution representation and modeling can be performed much more efficiently and robustly if the underlying surface tesselations have the special subdivision connectivity. In this paper, we propo...
