High-quality texture-based flow visualization on surfaces

In this paper, we present a high-quality texture-based approach for the visualization of vector fields on surface. It adopts a scheme of streamline enhancement by applying a 1D high pass filter to flow textures along the orthogonal flow direction to enhance the intensity contrast among streamlines and improve the image quality of flow textures. The scheme of edge detection and supplement is used in our approach to modulate the characteristic of particles flow. Our algorithm is image space based and can achieve a real-time rendering performance on a personal computer by using parallel processing ability of current graphics hardware.
