摘要：
传统的三维重构方法不适用于旋转式切片，该文针对旋转式切片提出了一种可行的三维重构方法，即基于B样条插值的重构方法，解决了旋转式切片的实体建模问题，在绘制时利用OpenGL的NURBS接口编程，比三角面片逼近等方法的重构时曲面的绘制质量有了显著提高。另外，该方法也适合于平行式切片的重构。

Abstract:
Traditional methods on 3D-restruction are not fit to rotary slice, a feasible method based on B-spline interpolation is posed, aimed at 3D-restruction on rotary slice. It can not only solve the problems on 3D modeling but also remarkably improve the quality compared with using triangular faces while drawing the curve because of using the NURBS interface programming in OpenGL. In addition, the method is also suited to parallel slice.
