System for using angle-weighted normals and flood-filling in geometric modeling
摘要：
A first geometry and a second geometry are accessed. They are positioned so that the first geometry and the second geometry at least in part intersect. The first geometry is divided into portions based on the intersection with the second geometry. At least a first portion of the first geometry is classified as being on one side of the second geometry. At least a second portion of the first geometry is classified as being on another side of the second geometry. At least a third portion of the first geometry is unclassified. The classifying includes comparing an angle weighted normal of a face with a property of the second geometry. The third portion is reclassified as either above the second geometry or below the second geometry according to the classification of a neighboring portion.
摘要（中）：

访问第一几何和第二几何。 它们被定位成使得第一几何形状和第二几何形状至少部分相交。 第一个几何被分为基于与第二个几何的交点的部分。 至少第一几何体的第一部分被分类为位于第二几何体的一侧。 第一几何的至少第二部分被分类为在第二几何的另一侧。 第一个几何的至少第三部分是未分类的。 分类包括将面部的角度加权法则与第二几何的属性进行比较。 根据相邻部分的分类，第三部分被重新分类为高于第二几何形状或低于第二几何形状。
