英文摘要： High-precision and large-scale numerical simulation for explosion problems has challenged the visualization of explosion fields. Based on the issues occurred to explosion field visualization, we propose the work of this project, where visualization and simulation are integrated together. This work will focus on the following topics: (1) Real-time visualization of large-scale explosion fields, where numerical results are directly visualized in the process of simulation. (2) High-definition visualization with the goal to reveal advantages of high-precision simulation, where high-definition volume rendering, high-quality streamlines and textures will be applied to generate explosion images in high definition. (3) Techniques of interactive visual analysis, such as focus+context, multiresolution analysis, association analysis, multiple coordinated views, etc., which will be used to deal with the analysis of large-scale explosion fields. (4) Theories and methods of parallel visualization for large-scale datasets, especially for large 3D flow fields, which are supposed to improve the efficiency of visualization and the response time of interaction. Based on the above work, we will finally build a parallel platform with the support of PC clusters and GPUs, and develop the corresponding visualization software and interactive visual analysis tools, to benefit the high-precision and large-scale simulation of explosion fields.
