Enhanced three-dimension vector field visualization based on fractional differentials
基于微分的增强型三维矢量场可视化

In order to enhance the 3D vector field visualization, this paper presentd an enhanced flow line algorithm based on texture. Firstly, it performed a volume line integral convolution to acquire a spatial-correlated texture; secondly, filtered the resulting texture with a fractional differential filter, resulting in high intensity contrast among the streamlines; thirdly, employed a texture-based volume rendering algorithm to depict the 3D vector field, and through the designing of the transfer function to see the inner structure of the vector field. The experiments show that this method enhances the flow line effectively, and makes the flow lines smoother, and it is easy to eliminate the visual clutter.
