| 摘 要： | 数字农业将工业可控生产和计算机辅助设计的思想引入农业。该文介绍了利用NURBS和OpenGl对虚拟棉花主要器官果枝、铃、主茎叶、果枝叶、花瓣、苞叶等进行建模的方法,得到了逼真的效果。与三维数字化方法相比,省去了大量精确数据的测量和数学表达式的拟合工作。

| Abstract: | Digital agriculture introduces the concepts of industrial production and CAD technique into agriculture.Based on NURBS and OpenGl,methods of establishing models of main cotton organ using techniques of computer graphics are presented and realistic results have been achieved.These organs are:fruit branch?bell?caulis leaf?fruit branch leaf?Petal?bract.Using NURBS we don't need to obtain an abundance of accurate data and bother with regression equation by contrast with three-dimensional digital. |
