【摘要】 绘制多边形可借助图形系统的硬件来实现 ,因此 ,隐式曲面的多边形化是隐式曲面绘制的主要方法 .文中提出了基于投影法的隐式曲面多边形化的方法 ,先在平面进行网格划分 ,再把平面上所有多边形面片映射到隐式曲面上 .该方法对在隐式曲面上有全部投影、部分投影和没有投影的多边形面片分别进行了讨论 .该方法也适用于绘制隐式裁剪曲面更多还原

【Abstract】 Polygonization is the main approach to rendering implicit surface, for the most of graphic systems use built in hardware to display polygons. We first partition a plane into grids, then map the planar meshes onto implicit surface. Three cases are encountered in the polygon surface relationship, namely: whole projection, part projection and no projection on the implicit surface. Part projection needs special treatment. This method can be applied to rendering implicit trimmed surface.更多还原
