It then bounces off a special grating that disperses light into its different wavelengths.

然后它被一个特殊的光栅反射，光栅将光分散到不同的波长。

Cinematographer Bill Pope built light grids around each bus.

电摄师比尔波普在每辆公共汽车周围建造了光栅。

Now, you can also shine light through many equally spaced slits -- this called a diffraction grating.

现在，您还可以通许多等 间距的狭缝照射光线——这称为衍射光栅。

But today, you learned about how to analyze the composition of a light source using diffraction grating and spectroscopy.

但是今天，您了解了如何使用衍射光栅和光谱分析光源的成分。

The video game graphics rendering pipeline has three key steps: Vertex Shading, Rasterization,   and Fragment Shading.

频游戏图形染管道有三个关键步骤：顶点着色、光栅化和片段着色。

But, they use raster scanning too, updating the brightness of little tiny red, green and blue pixels many times a second.

但是，他们也使用光栅扫描，每秒多次更新微小的红色、绿色和蓝色像素的亮度。

To do that, you need a spectrometer, a tool that uses diffraction grating or a prism to separate the wavelengths.

为此，您需要一个光谱仪，一种使用衍射光栅或棱镜来分离波长的工具。

And when you shine a light through one of these gratings, the diffraction lines are much more intense and easier to measure.

当你通一个光栅照射光线时，衍射线会更加强烈并且更容易测量。

Then the dark, rich part of the flower has a diffraction grating, such as you'd find on a CD, in the center, overlying the center of the flower.

然后花的深色、丰富的部分有一个衍射光栅，就像你在 CD 上看到的那样，在心，覆盖在花的心。

Thus, with rasterization,   we turn triangles into fragments which are groups of pixels that come from the same  triangle and share the same texture or color.

因此，通光栅化，我们将三角形变成片段，片段是来自同一个三角形并共享相同纹理或颜色的像素组。

When a triangle is rasterized, it covers a set  of pixels and the Z value or depth of the triangle is compared with the values stored in the  Z-Buffer.

当一个三角形被光栅化时，它覆盖一组像素，并且三角形的 Z 值或深度与存储在 Z 缓冲区的值进行比较。

To pull this off, computers needed an extra piece of hardware that could read characters out of RAM, and convert them into raster graphics to be drawn onto the screen.

为了实现这一点，计算机需要一个额外的硬件来从 RAM 读取字符，并将它们转换成光栅图形以绘制到屏幕上。

Chu demonstrated the " invisibility" at the event, and he made his legs disappear directly with the help of a magical material called " lenticular grating" that allows light to be refracted regularly.

褚在活动现场演示了 " 隐形" ，他借助一种名为 “柱镜光栅”的神奇材料，让光线有规律地折射，直接让自己的双腿消失了。

For a given fragment we take the center of each  pixel and use the vertex normals and coordinates of the pre-rasterized triangle to calculate the  barycentric normal of that particular pixel.

对于给定的片段，我们取每个像素的心，并使用预光栅化三角形的顶点法线和坐标来计算该特定像素的重心法线。

If the graphics card saw the 8-bit code for the letter " K" , then it would raster scan the 2D pattern for the letter K onto the screen, in the appropriate position.

如果显卡看到字母“K”的 8 位代码，它就会将字母 K 的 2D 图案光栅扫描到屏幕上的适当位置。

As a result, the process and  calculations within vertex shading, rasterization, and fragment shading are recalculated for every  single frame once every 8.3 milliseconds for a game running at 120 frames a second.

因此，对于以每秒 120 帧的速度运行的游戏，每 8.3 毫秒就会重新计算一次顶点着色、光栅化和片段着色的进程和计算。
