枝条形状 meaning in English

branch form

Aiming at the lack of traditional ploting method in the areas of three dimension graphics , the b - spline surface is adopted . in order to more easily build the b - spline surface the control points are replaced with one center point during the storage , and make it clear to simulate the curve of branches
在三维图形的绘制方面，针对传统绘制方法的不足，采用b样条曲面来构造三维几何模型，在曲面的生成及存储过程中用一个中心点代替多个控制顶点，将对曲面的控制转为对曲线的控制，使得对枝条形状的模拟更加方便直观，并且减少了存储空间。
