本文提出了一种基于骨架的参数化实体模型-- Ball B样条曲线（BBSC）。研究了它们的基本性质、算法和建模方法。BBSC直接以B-Spline函数形式定义对象（不是过程方法，如扫掠），使用控制球代替B-Spline曲线中的控制点。BBSC不仅描述了三维实体中的每一个点，而且直接以B样条的形式给出了它的中心曲线。因此，该表示方法在建模、操作和变形方面更加灵活。
This paper proposes a parametric solid representation of freeform tubular objects - Ball B-Spline Curves (BBSCs), which are skeleton based parametric solid model. Their fundamental properties, algorithms and modeling methods are investigated. BBSC directly defines objects in B-Spline function form (not a procedure method, like sweeping), that uses control ball instead of control point in B-Spline curve. BBSC describes not only every point inside 3D solid objects, but also provides its center curve in B-Spline form directly. So the representation is more flexible for modeling, manipulation and deformation.
