Abstract: An improved method is presented for modeling leaf venation pattern.L-system is introduced into the Runions’ modeling method to solve the slow growth of main and lateral veins.As a step towards the whole method,a new dart-throwing algorithm is used to get homogeneous distributed auxin sources in each simulation loop,which effectively improves the drawing speed of whole method.The results verify that the improved method can get more realistic venation pattern by quicker speed.

摘要: 提出了一种改进的叶脉建模方法。该方法将L-system加入到Runions的叶脉建模方法当中,较好地解决了主侧脉生长比较慢的问题。作为整体算法中的一步,采用一种新的dart-throwing算法得到均匀分布的营养点集,有效地提高了整个算法的绘制速度。实验结果表明,改进后的方法能够以更快的速度生成更加逼真的叶脉模型。
