摘要 隐式曲面多边形化是隐式曲面绘制的常用算法。该文提出了一个隐式曲面快速多边形化算法。首先用Bloo-menthal的多边形化算法生成一个粗糙的初始网格,再进行网格优化提高网格规则性,最后用多边形细分策略细分优化后的网格。实验结果表明,该算法在网格生成速度和网格规则性上都胜于Bloomenthal的多边形化算法。 To convert implicit surfaces into polygons is a popular approach in rendering implicit surfaces.This paper presents a fast tessellation approach for implicit surfaces.We first use Bloomenthal's polygonizer to get a coarse initial mesh,then the mesh is optimized to improve the quality of the triangles,finally the refined mesh is subdivided using a polyhedral subdivision scheme and a mapping procedure.Experiments show our method produces better results than Bloomenthal's polygonizer both in speed and mesh regularity.
