Abstract :
The speed of calculating, tracking and filling the isolines has a direct impact on the performance of user interaction. In this paper, we begin with the serial algorithm of visualization and implement its parallel algorithm. First, we divide the Delaunay grids generated from the PEBI grids into several regions. Calculation, tracking of isolines and calculation of saturation are implemented in each region respectively. Then the tracking results of each region are integrated for the entire work area. The parallel examples using OpenMP on computers with dual-core/quad-core are given at the end of this paper. The experimental results show that the parallel processing can greatly reduce the time required for data processing in visualization.
