水生植物的模拟一直是计算机图形学研究的热点和难点。对于叶片较长且卷曲的水草仿真,采用Bezier曲线生成叶片的主脉(中线)及边缘曲线,通过偏移中线或边缘曲线上的控制点进行曲线插值生成侧中线,采用三角化方法生成叶片框架的网格,直接使用多重纹理产生叶子上的暗斑。实验结果表明,该方法能较好地表现水草的形态并有较高的绘制效率。
Simulation of aquatic plants has always been a difficulty and central issue. For simulation o5 song anu curt leaf of water plants, the method of Bezier curve can be used to generate the major veins (median line) and the edge of curve of the leaf. By moving the control points on the central line or boundary curve, curve interpolation can be applied to generate the side central line. The gird of the leaf framework is generated by the method of triangulation and the dark spot on the leaf is generated by using muhitexturing. The result shows that the method can draw the water plants quite well and is very efficient.
