简介

Blender同时提供 和 NURBS 。贝塞尔曲线，NURBS曲线和曲面都是根据一组“控制点”（或“控制顶点”）定义的，这些点定义了一个“控制多边形”。

使用曲线而非多边形网格的主要优势是，曲线使用更少的数据来描述物体结构，所以在建模时可以使用更少的内存和存储空间来产生结果。然而，此方法所建的曲面会增加渲染时的负担。

Certain modeling techniques, such as,are possible only using curves. On the other hand, when using curves,vertex-level control is more difficult and if fine control is necessary,mesh editing may be a better modeling option.

They are also widely used in animation, both as for objects to move along (see constraints below)and as to change the properties of objects as a function of time.
