中文摘要：

提出一种基于纹理的增强型3D矢量场可视化算法，可显著地改善传统纹理法的绘制质量，首先通过对3D纹理的线性卷积运算生成具有空间相关性的卷积纹理；然后对卷积纹理进行高通滤波，以增加流面内流线之间强度的对比；最后通过体绘制方式展示3D卷积纹理，借助权重区域，该算法可以显示用户感兴趣区域或特征区域，避免卷积数据过多引起的紊乱及相互遮挡。

英文摘要：

This paper presents an enhanced 3D flow visualization algorithm based on the 3D line integral convolution （LIC） and volume rendering techniques. Given an input 3D vector field, a 3D line integral convolution is at first performed to get a spatial-correlated texture. The resulting texture is then filtered with a 1D high-pass filter, resulting in high intensity contrast among the streamlines in the stream surfaces. An importance-driven volume rendering algorithm is employed to depict the interesting regions, and by which the distracting occlusions and visual clutter are effectively eliminated.
