Triangle Strip Multiresolution Modelling Using Sorted Edges
نویسندگان
چکیده
This paper presents a new multiresolution model based exclusively on the triangle strip primitive. The model is independent of the initial set of triangle strips and the simplification method used to obtain the lower resolution versions of the original model. The information stored in the data structures is sorted to minimise the time needed to recover a Level of Detail (LoD). The orientation of triangles in each strip is maintained as the model is simplified, so back-face culling can be used. The main result is a dramatic improvement in the rendering time.

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 کاملMultiresolution Triangle Strips
Most of the previous multiresolution models use exclusively the triangle graphic primitive both in the data structure and in the rendering stage. Only a few models use another graphic primitive in this rendering process and just one uses the triangle fan as the basic primitive of the model. In this paper we present the first multiresolution model, Multiresolution Triangle Strips, that uses the ...
متن کاملMultiresolution Modelling of Polygonal Surface Meshes Using Triangle Fans
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 m...
متن کاملDStrips: Dynamic Triangle Strips for Real-Time Mesh Simplification and Rendering Category: Scientific Research
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 کاملHierarchyless Simplification, Stripification and Compression of Triangulated Two Manifolds
In this paper we explore the algorithmic space in which stripification, simplification and geometric compression of triangulated 2-manifolds overlap. Edge-collase/uncollapse based geometric simplification algorithms develop a hierarchy of collapses such that during uncollapse the reverse order has to be maintained. We show that restricting the simplification and refinement operations only to, w...
