Cephalic, or head-first, is the first type, and furthermore the most common and optimal presentation for easy delivery is a type of cephalic presentation called vertex, which includes complete flexion of the head as well.

露，第一种类型；进一步说，对于顺产来说最常见、最佳露，是一种称为顶露露，包括完整部俯屈。

When two lines meet at a point, or vertex, an angle is formed.

当两条线相交在一点，即顶点时，就形成了一个角。

So we can see here it says, " Consider reducing the number of triangles and consider reducing the work in the vertex shader."

“考虑减少三角形数量，并考虑减少顶点着点工作。”

These two stars, which form the vertices of the Summer Triangle along with Deneb, are clearly visible during summer from places in the mid-northern latitudes.

这两颗恒星和天津四一起构成了夏季大三角，在夏季从纬度地区可以清晰地看到。

If I hover over the vertices row, here I can get an idea of, OK, what's the summary for that draw call for the vertices submitted to the scenes?

如果我在顶点行上面悬停，我就能够了解那个顶点绘制调用提交到场景总数是多少？

Here’s a closer look at what happens when we make the folds at this vertex.

下面仔细看看我们在这个顶点做折叠时发生什么。

But thinking of colors on the cube, you're naturally led to an interesting combinatorial question: Is there a way to color the cube so that the three neighbors of any given vertex will always represent red, green and blue.

但想到立方体上颜，自然地联想到一个有趣组合问题：是否存在一种给立方体上方法，使得任何一个顶点三个邻接面总是代表红、绿、蓝三种颜。

Additionally, if you're curious as to how video game graphics work, we have a separate video that explores all the steps such as vertex shading, rasterization, and fragment shading.

另外， 如果好奇视频游戏画面是如何工作，我们有一段单独视频详细介绍了所有步骤，比如顶点着、光栅化和片段着。

Three, you say, well, look, it's got four electric and four magnetic because you associate the faces with electric and you associate with the vertices with the magnetic.

说有四个电和四个磁，因为把面与电联系起来，把顶点与磁联系起来。

You're going to just basically put a toll keeper at every single node and every single graph edge, every node, every vertex, every edge.

基本上就是在每个节点和每条图边， 每个节点， 每个顶点， 每条边上都设置一个收费员。

V stands for vertices, E for edges, F for faces.

V 代表顶点，E 代表边，F 代表面。

Dou Zhi Li is split into 10 different stages, and when the body acquires 10 stages of Dou Zhi Li, it can better condense the Dou Zhi vertex, becoming a well-respected Dou Zhe!

斗智力分为十个不同阶段， 当身体获得了十个阶段斗智力之后， 就可以更好凝聚斗智顶点， 成为备受尊崇斗者！

When the sixpointed star was laid perfectly over the Great Seal of the United States, the star's top vertex fit perfectly over the Masonic all-seeing eye ...

当六角星完美地铺设在美国国徽上时, 这颗星顶点完美地贴合在共济全视之眼上。

Here's a closer look at what happens when we make the falls at this vertex.

下面仔细看看我们在这个顶点坠落时发生什么。

So let's focus on a single vertex.

所以让我们专注于一个顶点。

So the total number of vertices here  would not be N but N plus N choose four total intersection points.

所以这里顶点总数不是N，而是N加上n选4总交点数。

Let's begin with the first step, called vertex shading.

让我们从第一步开始，叫做顶点着。

Or I could put a tail on that, and that would be another edge, another vertex.

或者我可以在那上面加一条尾巴，这样就多了一条边和一个顶点。

You attach numbers to every vertex in the following way.

您以如下方式为每个顶点赋予编号。

But the key is to treat this as a new graph  where those intersection points are them vertices.

但关键是要将这视为一个新图，其那些交点就是顶点。
