The driver might allocate a larger buffer after this point, or you might need to reduce your vertex count.
在这点之后，驱动可能会分配一个更大的缓存，或者你可能需要降低你的顶点数量。
The algorithm works because if a vertex has no successors, it must be the last one in the topological ordering.
算法能够执行是因为，如果一个顶点没有后继，那么它肯定是拓扑序列中的最后一个。

When I created the VertexBuffer, I mentioned that you can assign several kinds of information to a vertex — colors for example.
创建VertexBuffer时，我曾提到可以为一个顶点指派多种类型的信息——颜色也是其中之一。
The vertex positions are transformed from clip-space to window space via the Perspective Divide and the Viewport Transform.
经过视角除法和视口变换两步，顶点的位置就从裁剪空间变换到了窗口空间。
Find all the edges from the newest vertex to other vertices that aren't in the tree. Put these edges in the priority queue.
找到从最新的顶点到其他顶点的所有边，这些顶点不能在树的集合中。把这些边加入优先级队列。
Of course, in the vertex shader I just write a general equation so we don't have to deal with each special case individually like this.
当然，在顶点着色器中，我们可以使用一个通用的公式来计算和叠加光照，而不需要像上面提到的那样分别应付各种不同的情形。
As it turns out, it is easier to keep only one edge from the tree to a given fringe vertex in the priority queue at any given time.
这样做了以后，要使优先级队列中在任意时刻只保持一条从树中顶点到某边缘点的边就变得容易了。
To deal with the points on the line aligned with a segment vertex, clauses that count only the segments that are lower than the line are necessary.
要处理与一个线段顶点对齐的线上的点，必须使用仅计算低于该线的线段的子句。
Batching dynamic objects has certain overhead per vertex, so batching is applied only to meshes containing less than 900 vertex attributes in total.
批处理动态物体需要在每个顶点上进行一定的开销，所以动态批处理仅支持小于900顶点的网格物体。
Texture coordinates are named (s, t) in order to distinguish them from the (x, y) used for vertex positions (in literature, (u, v) is commonly used instead).
将纹理坐标命名为(s,t)是为了与用于表示顶点位置的(x,y)区分开来(从文字角度来讲，(u,v)更为常用)。
The constructor of VertexArray takes the number of vertices (eight), the number of components per vertex (x, y, z), and the size of each component (one byte).
