## V-O Tessellation: An Algorithm for Polyline Symbolization

• 摘要: 本文针对线符号中基本线型绘制质量与效率问题,对比分析了5种典型线对象分解与绘制方法。在V分解的基础上,提出一种V-O分解与绘制方法,提高了V分解方法三角化的适应性,减少了V分解方法的顶点、三角形以及三角形条带的个数。能够支持颜色线、纹理线、渐变线等基本线型的绘制,支持反走样。实验表明,本文方法具有较强的适应性和较高的绘制效率。

Abstract: Quality and efficiency in basic linear drawing, comparative analysis of the five kinds of typical polyline tessellation and drawing methods are presented in this paper. On the basis of V tessellating, we propose a V-O tessellating and rendering method to improve the adaptability of the V triangulation decomposition to reduce the number of vertices, triangles and triangle strips. This method can support anti-aliasing color polyline, texture polyline, and the gradient polyline. Experimental results show that the proposed method is adaptable and performs well.
