Abstract: An indexed list of vertices is generated to represent a polygon. The indexed list is ordered so as to define one or more boundaries of a polygon, where each element in the indexed list of vertices specifies respective coordinates in an at least two-dimensional space. A description of several component shapes that make up the polygon is generated, where the description includes indices into the indexed list of vertices. The indexed list of vertices and the description of the component shapes are provided to a computing device for rendering the polygon.

Abstract translation: 生成索引的顶点列表来表示多边形。 索引列表被排序以定义多边形的一个或多个边界，其中索引的顶点列表中的每个元素在至少二维空间中指定相应的坐标。 生成组成多边形的几个组件形状的描述，其中描述包括索引的顶点列表中的索引。 索引的顶点列表和组件形状的描述被提供给用于渲染多边形的计算设备。
