The team also used a virtual camera system, where the cinematographer referenced an iPad showing rough animated footage.

该团队还使用了一个虚拟摄像机系统，摄影师运用了一台 iPad 来生成效果动画。

Finally, a virtual camera is added  and the scene is rendered and brought to life.

最后，添加虚拟摄像机并渲染场景并使其栩栩如生。

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。

The other billions of rays do the same thing resulting in a single image with the proper  3D perspective from the virtual camera.

其他数十亿条射线做同样的事情，从而产生来自虚拟相机的具有适当 3D 视角的单个图像。

So there is no world that I can show the actors other than having them come over and look at the monitor and see the results of my virtual camera pass.

因此，除了让演员们过来看看监视器并查看我的虚拟相机通道的结果之外，我无法向他们展示任何世界。

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。
