In this paper, a method to model rice leaves is proposed. The silhouette of the leaf is defined by inputting a grayscale which is converted from a scanned rice leaf image. By creating many spline curves and calculate the intersections of them, and rice leaf veins are constructed by sweeping these generating curves along these intersections, then the rice leaf three-dimensional grid model is established. After that, the rice leaf grayscale image as the texture map which provides texture information and mater...
