In this thesis, a novel method is proposed to raise the quality of triangular mesh generation. Whereas previous refinement methods mainly focus on inserting a new vertex into the circumcenter of a skinny triangle or tetrahedron, the proposed method is striving to insert a vertex near the geometric center of an effective region.

鉴於前人提出之refinement方法，主要乃以插入形状低劣之三角形外接圆之圆心，以提高网格品质；本文提出一新的思考观点，乃试图插点於其影响区域之中心，以提高其品质。

This paper demonstrates three different strategies of point distribution for two-dimensional problem. Points are distributed at gravity point,at circumcircle center and at the edge of Voronoi.
