1·In this architecture, all data for each vertex must be available at the same time.
在这一架构中，来自各顶点的所有数据都必须同时可用。
2·Because one vertex can only have one normal, you must duplicate the vertices as well.
由于一个顶点只能有一条法线，所以你还要复制顶点。
3·In the first feasible region above, the optimal solution is the right vertex of the solution space.
在上面的第一个可行域中，优化解决方案是解析空间中的右顶点。
4·If the horizontal line drawn is aligned with a polygon vertex, then only the segments that are below the line are counted.
如果所绘制的水平线与一个多边形顶点对齐，那么只计算位于该线下方的部分。
5·The vertex positions are not enough.
仅有顶点位置还不够。
