Han-Wei Shen - framework for managing and rendering large scale time-varying data using the wavelet-based time-space partitioning (WTSP) tree. We utilize the hierarchical TSP tree data structure to capture both spatial and temporal locality and coherence of the underlying time-varying data and exploit the wavelet transform to convert the data into a multiresolution spatio-temporal representation.
Han-Wei Shen new parallel multiresolution volume rendering algorithm for visualizing large data sets. Using the wavelet transform, the raw data is first converted into a multiresolution wavelet tree. wavelet tree is traversed according to the user-specified error tolerance, data blocks of different resolutions are decompressed and rendered to compose the final image in parallel.
