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

巧板是一小块拼图游戏，由平的形组成，形放在一起可以形成其他形状。

Admittedly, this is a pretty ugly filled polygon.

诚然，是一非常丑陋的填充形。

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

是因为该算法不需要对任何形进行排序，因此速度更快。

This works with larger polygons too.

也适用于更大的形。

So no one was bisecting polygons to find Pi ever again.

If a pixel is entirely inside of a polygon, it gets fully colored.

如果一像素完全在形内部，它就会完全着色。

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

计算机填充形的速率称为填充率。

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

重要的是， 它也适用于一数较少的形，包括形、六形和五形。

But if the polygon only grazes a pixel, it’ll get a lighter shade.

但是如果形只擦过一像素，它会得到一更浅的阴影。

To make things easier to follow, we’re going to color the polygons differently.

为了让事情更容易理解，我们要给形涂上不同的颜色。

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

But for more complex shapes, triangles are better -- what are called polygons in 3D graphics.

但对于更复杂的形状，三角形更好——在 3D 图形中称为形。

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像素到形的最近距离。
