Christian Lauterbach: Interactive Ray Tracing of Massive and Deformable Models. (Under the direction of Dinesh Manocha.) Ray tracing is a fundamental algorithm used for many applications such as computer graphics, geometric simulation, collision detection and line-of-sight computation. Even though the performance of ray tracing algorithms scales with the model complexity, the high memory requir...

Abstract A frequency accuracy study is presented for the isogeometric free vibration analysis of Mindlin–Reissner plates using reduced integration and quadratic splines, which reveals an interesting coarse mesh superconvergence. Firstly, error estimates discretization with splines are rationally derived, where degeneration to Timoshenko beams discussed as well. Subsequently, in accordance these...

At present, we design a framework for streaming of 3D static model with rate adaptation techniques called TCP-Friendly Rate Adaptation. The 3D model in our framework is compressed with progressive meshes method [Hoppe96]. Exploited the dependency from progressive meshes, we transmit 3D model progressively.

In this paper, we present a framework that integrates three-dimensional (3D) mesh streaming and compression techniques and algorithms into our EVE-II Networked Virtual Environments platform, in order to offer support for large-scale environments as well as highly complex world geometry. This framework allows the partial and progressive transmission of 3D worlds as well as of separate meshes, ac...

Simplification techniques have mainly been applied on static models. However in movie and game industries, many models are designed to be animated. We extend the progressive mesh technique to handle skeletallyarticulated meshes in order to obtain a continuous levelof-detail (CLOD) representation that retains its ability to be animated. Our technique is not limited to any simplification metric, ...

Progressive meshes are an established tool for triangle mesh simplification. By suitably adapting the simplification process, progressive hulls can be generated which enclose the original mesh in gradually simpler, nested meshes. We couple progressive hulls with a selective refinement framework and use them in applications involving intersection queries on the mesh. We demonstrate that selectiv...

In this paper we present a technique for transforming a tetrahedral mesh into a progressive representation based on half edge collapses. This allows the efficient transmission of the mesh from a remote computer where the simulation was computed to a visualization computer. During the transmission the user can start visualizing while the transmission is still in progress. We show a technique for...

Many multiresolution methods have been proposed. Most of them emphasize accuracy and hence are slow. Some methods may be fast, but they may not preserve the geometry of the model. Although there are a few real-time multiresolution methods available, they are developed mainly for handling large terrain models. In this paper, we present a very efficient multiresolution method for continuously red...

Deformable surface models are often represented as triangular meshes in image segmentation applications. For a fast and easily regularized deformation onto the target object boundary, the vertices of the mesh are commonly moved along line segments (typically surface normals). However, in case of high mesh curvature, these lines may not intersect with the target boundary at all. Consequently, ce...
