轮廓字网格编织带修饰效果的实现

IMPLEMENTATION OF FONT DECORATED BY MESH FITTING

利用计算机进行设计各种字形修饰效果一直是计算机图形学的重要内容之一 .本文给出了在轮廓字表面上构造网格点 ,基于这些网格点进行 Delaunay三角剖分 ,并转换为 3- 4网格 ,最后在网格上实现编织带修饰效果的具体实现方法 .其中 3- 4网格由良构的四边形单元和少量辅助三角形单元构成 。

Using computer to design all kinds of decorative font is always an important field of Computer Graphics.This paper gives an algorithm for constructing internal points and their Delaunay triangulation in arbitrary character outlines, converting them into 3,4-mesh, and fitting a knotwork design in the end. This 3,4-mesh is composed of well-formed quadrilateral elements, with few supporting triangular elements, upon which the florid knotwork design may be realised.
