基于截面线的隐式曲面多边形化
Section-curves Based Polygonization for Implicit Surfaces
【摘要】 提出了基于截面线的隐式曲面多边形化方法 .用一系列平行平面去截隐式曲面 ,根据正负法产生截面线 ,再对截面线进行拓扑重构和几何重构 ,实现了隐式曲面的多边形化 .与传统的隐式曲面绘制方法相比 ,所提出的方法具有效率高、适合于交互设计等特点 .
【Abstract】 This paper gives section curves based polygonization for implicit surfaces.To realize polygonization for implicit surfaces,we cut the implicit surfaces using a range of parallel planes,get section curves by positive negative methods,and then reconstruct on topology and geometry to these curves.Comparing with the original methods of implicit surface rendering,the methods given in the paper are efficient and adaptive to interactive design.
