Seed Filling Preprocessing: A universal visualization preprocessing method in irregular grids
Xiaofu Du, Liu Huilin · 2018
In order to reduce the computational waste in the visualization process, a universal visualization preprocessing method is proposed in this paper: Seed Filling Preprocessing. The whole physical field is divided into several pixels by resolution, and then the point location and interpolation of each pixel is finished ahead of time. When the concrete visual elements, such as streamline etc., are calculating and drawing, each sampling point will not be calculated on the basis of grid cell, but of the pixel in which it is. This method is applicable to all kinds of visualization techniques, including pixel cloud, streamline, texture, etc. The experimental results show that the method can effectively improve the efficiency of various visualization techniques.
