This requires a light simulation program that is able to create an image of this virtual scene that looks exactly the same as it would in reality.

这就需要一个光线仿真程序，该程序能够创造一幅与现实场景看起来完全相同场景图像。

Photorealistic rendering means that we put virtual objects in a scene, assign material models to them, and then run a light simulation program to create a beautiful image.

逼真图形渲即我们把物体放到场景里，给材料模型，然后运行光仿真程序来创建一个美丽图像。

Make sure to have a look at the paper, there are many more experiments that went similarly, including a case where the AI found a bug in a physics simulation program to get an edge.

请一定要看一下这篇论文，还有更多类似实验，其中有一个例子是 AI 在一个物理仿真程序里找到了一个漏洞以取得优势。

It is typically done by using light simulation programs where we use the laws of physics to simulate the path of millions and millions of light rays as they bounce off of different objects in a scene.

我们通常使用光仿真程序，用物理规律来模一个场景中从不同物体上反射出数百万条光线路径。
