The first part of the study included tests with driving simulation programs.

研究的第一部分包括驾驶模拟程序的测试。

It is also highly practical as it can be plugged in as a standard material model without any crazy modifications to the simulation program.

它还可以直接作为标准的材料模型来使用，不用对程序做太大的改动，这非常的好用。

Now that we know what iridescence is, the next step is obviously to infuse our light simulation programs to have this awesome feature.

现在，我们已经知道了什么是彩虹色斑，显然，下一步就是把这个酷炫的效果用光模拟程序展现出来。

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.

逼真图形渲染即我们把虚拟物体放到场景里，给它分配材料模型，然后运行光仿真程序来创建一个美丽的图像。

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真程序，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图像。

Using light simulation programs, we are able to populate a virtual scene with objects, assign material models to them, and create a beautiful, photorealistic image of this digital scene.

我们能够用对象填充虚拟场景，为它们制作材料模型，产生一幅美丽逼真的数字场景图。

And now, the entirety of this course is available free of charge for everyone where we learn the theory of light from scratch and implement a really cool light simulation program together.

现在，这门课的全部内容对我们每个人都是免费的，在这里，我们可以从零开始学习光理论，并实现一个非常酷的光模拟程序。

What is even less known, is that if we try to use a light simulation program to make an image with leather, we'll be surprised to see that it also shows a pronounced goniochromatic effect.

更加鲜为人知的是，如果我们尝试用光模拟程序模拟出一张皮革制品的图像，我们会惊讶地发现，这张图像也会显示出明显的彩虹色斑效果。

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，用物理规律来模拟一个场景中从不同物体上反射出的数百万条光线路径。

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 在一个物理仿真程序里找到了一个漏洞以取得优势。
