摘　　要：讨论了对水稻叶进行形态建模可采用的方法,介绍了一种基于NURBS曲面的水稻叶形态建模的方法,叙述了控制点的计算过程。利用NURBS在形状定义和设计方面的优点,可以根据实际情况灵活方便地对根据模型建立的叶片进行调整。本模型通过OpenInventorJava实现绘制渲染,效果良好。This article discusses the approaches to model the rice leaf, introduces a model of rice leaf based on NURBS and introduces the calculating of the control points and the knots. By means of the advantage of NURBS in shape definition and design , We can adjust the leaf based on the model according to the fact smartly and expediently .We have realized the model by Open Inventor Java and the effect is good.
