基于样条曲线的三维字造型系统的研究与实现

Study and realization of three dimensional character modeling system based on spline curve

建立了一个基于Bezier样条曲线的三维字造型系统,采用基于凹凸顶点判断和内外边界拼合的三角剖分算法,较好地解决了字型轮廓的三角剖分问题,并运用Bezier曲线实现了三维字模型中的各种倒角和圆角效果。

A three dimensional character modeling system based on Bezier spline curve is presented in this paper. The triangulation problem of character profile is solved by using determination of convex-concave vertices and connecting the outer border of a poly- gon with its inner borders. Some chamfer and fillet in the character model are realized by using Bezier curve.
