摘　　要：矢量场可视化是科学计算可视化中最具挑战性的研究课题之一。基于纹理的线积分卷积(LIC)能够很好地显示矢量运动方向,但是计算耗时。本文利用LIC的并行性,提出一种累进的矢量场可视化方法 累进LIC(ProLIC)。ProLIC通过子场分割、子图交错和泼溅快速显示LIC略图,实现累进可视化。交互式ROI ProLIC快速显示兴趣区域,提高可视化效率。最后进一步拓展ProLIC,提出面向大规模三维矢量场可视化和面向网络可视化的Volume /Network ProLIC模型。Vector field visualization is one of the most challenging research issues for Visualization in Scientific Computing (ViSC). Texture based Line Integral Convolution (LIC) can effectively visualize direction of the vector field. However, it is too time consuming. ProLIC (Progressive LIC) was proposed to exploit LIC parallelism and hence a LIC image can be progressively computed and refreshed by segmentation, interleaving and splash techniques, with sketch LIC image quickly shown. ProLIC can be used for interactive ROI (Region Of Interest) visualization. ProLIC was further extended to Volume/Network ProLIC Model for large-scale Volume LIC and network oriented LIC.
