This report presents a dynamic mesh representation that is designed to display the results of interactively sampling a 3D environment. The mesh generator takes samples comprising a world space location, RGB color value, and sampled ray direction, and assembles them into a 3D triangle mesh. From this representation a complete image can be constructed and displayed, both from the initial view, an...

-Representation of video objects using hierarchical 2D content-based meshes for accurate tracking and level of detail (LOD) rendering have been previously proposed, where a simple suboptimal hierarchical mesh design algorithm was employed. However, it was concluded that the performance of the tracking and rendering very much depends on how well each level of the hierarchical mesh structure fits...

A new approach to comparison of dynamic meshes based on Hausdorff distance is presented along with examples of application of such metric. The technique presented is based on representation of a 3D dynamic mesh by a 4D static tetrahedral mesh. Issues concerning space-time relations, mesh consistency and distance computation are addressed, yielding a fully applicable algorithm. Necessary speedup...

We present a method to synthesize procedural models with global structures, such as growth plants, on existing surfaces at interactive time. More generally, our approach extends shape grammars to enable context-sensitive procedural generation on the GPU. Central to our framework is the unified representation of external contexts as texture maps. These generic contexts can be spatially varying p...

The use of 3D data in the form of triangle meshes is nowadays a widespread phenomenon. A great many examples of using this kind of data can be found in engineering applications or in film and gaming industry. These examples include not only static, but also dynamic meshes – 3D animations. This kind of data representation is usually voluminous and needs to be compressed for efficient storage and...
