Furthermore, by animating  the camera around or changing its field of view, the view plane will correspondingly change.

此外，通过使摄像机动起来或改变其视野，视图平面也会相应地改变。

With computer-generated images or CGI, the 2D  image is represented by a view plane in front of the virtual camera.

对于计算机生成的图像或 CGI，2D 图像由虚拟相机前面的视图平面表示。

This view plane has the  same pixel count as the final image, so a 4K image has 8.3 million pixels.

该视图平面具有与最终图像相同的像素数，因此 4K 图像具有 830 万像素。

If we were to show billions of rays, the  scene would quickly become inundated with lines, so let's simplify it down to a single ray  running through one pixel of the viewing plane.

如果我们要展示数十亿条射线，场景很快就会被线条淹没，所以让我们将其简化为一条穿过观察平面一个像素的单条射线。

In order to create this image  on the view plane, a total of 8.3 billion rays, which are a thousand rays per pixel, are sent out  from the virtual camera through the view plane and into the scene.

为了在视图平面上创建该图像，总共有 83 亿条射线（每个像素一千条射线）从虚拟相机发出，穿过视图平面进入场景。
