View-Dependent Interactive Visualization Methods for Multiresolution Datasets in JaVis

摘要

In this paper, view-dependent multi-resolution data visualization techniques are discussed, including I/O optimized multi-resolution data organizing, view-dependent clipping methods with the viewing frustum, rendering with adaptive resolution and fast search methods for target datasets. A specified strategy is chosen for obtaining parameters of the viewing frustum and transferring with multiresolution operator plug-in. Bounding-box method and parent-child relationship between different resolution level are used to speed up searching target datasets and clipping viewing frustum.
