Vector field visualization has been a focus of visualization research. Streamlines provide good representation of local information, and are also utilized to give global vision in 2-dimension vector fields. In this paper, streamline-based methods are analyzed in signal processing aspect, and their efficiency and inefficiency in frequency domain are pointed out. A new method, textured streamline, is proposed and analyzed. The new method has clearer meaning in frequency domain, and can be implemented more easily with lower cost.
