Mathematicians estimated it by inscribing polygons in circles.

数学家通过在圆内接来估算这个数值。

The circle, which is effectively a Reuleaux polygon with an infinite number of sides, has the largest.

圆是一个有效鲁洛正有无数条，有最大面积。

The tangram is a dissection puzzle consisting of seven flat polygons which are put together to form shapes.

七巧板是一个小块拼图游戏，由七个扁平组成，这些放在一起可以成其他状。

And over the years, more polygon lines were added, making the players look more and more lifelike.

并且经年累月，增加线条，让球员们看起来越来越逼真。

That’s because this algorithm doesn’t need to sort any polygons, which makes it faster.

这是因为该算法不需要对任何进行排序，因此速度快。

This works with larger polygons too.

这也适用于大。

Importantly, it also works for some polygons with fewer sides, including heptagons, hexagons, and pentagons.

重要是， 它也适用于一些数较少，包括七、六和五。

Also they taught students how to draw polygon.

并且教学生画。

They may be triangles or polygons, or different kinds of shapes that you don't normally expect in a building.

它们可能是三角或，或者您通常不会在建筑物中看到各种状。

Then Z-buffering starts with the first polygon in its list.

然后 Z 缓冲从其列表中第一个开始。

In short, Z-buffering keeps track of the closest distance to a polygon for every pixel in the scene.

简而言之，Z 缓冲会跟踪场景中每个像素到最近距离。

With scanline rendering coloring in all the polygons, our teapot looks like this.

在所有中都使用扫描线渲染着色，我们茶壶看起来像这样。

As an example, we’ll pick 3 polygons from different parts of our teapot.

例如，我们将从茶壶不同部分挑选 3 个。

Polygons are constantly being shuffled around in memory and changing their access order.

在内存中不断地被洗牌并改变它们访问顺序。

When it’s done with Polygon A, it moves on to the next polygon in its list, and the same thing happens.

完成 A 后，它会移动到其列表中下一个，同样事情也会发生。

Because polygons are triangles, if you intersect one line, you have to intersect with another.

因为是三角，如果你与一条线相交，你必须与另一条线相交。

The rate at which a computer fills in polygons is called the fillrate.

计算机填充速率称为填充率。

For a simple example, let’s consider just one polygon.

举一个简单例子，让我们只考虑一个。

An interesting problem arises when two polygons have the same distance, like if Polygon A and B are both at a distance of 20.

当两个具有相同距离时会出现一个有趣问题，例如 A 和 B 距离均为 20。

Now, because we didn’t sort the polygons, it’s not always the case that later polygons overwrite high values.

现在，因为我们没有对进行排序，所以后面不会总是覆盖高值。
