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.

这就需要一个光线的仿程序，该程序能够创造一幅与现实场景看起来完全相同的虚拟场景像。

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.

逼渲即虚拟物体放到场景里，给它分配材料模型，然后运行光仿程序来创建一个美丽的像。

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，还有更多类似的实验，其中有一个例子是 AI 在一个物理仿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.

通常使用光仿程序，用物理规律来模拟一个场景中从不同物体上反射出的数百万条光线路径。
