Sonia, can you explain it to us?

James 说，你还可以用你手机里的照片做贴图。 You can also make stickers using pictures from your phone。智行，主词，can do something using。Using 所引导的分词片语用说明使用某样东西做某事。 句。

Wrinkles, engravings, grain on a wooden table are excellent examples of details that we can add to our models, and computer graphics people like to collectively call these things displacement maps.

比如木桌上的皱纹、雕刻、颗粒感等等就是我们想要加到模型上的细节的很好的实，计算机图形学研究者们喜欢把他们统称为“置换贴图(displacement maps)”。

So we redid the way we light our characters in our menus and this is what's called a cube map.

所以我们重新设计了在菜单中点亮角色的方式，就是所谓的立方体贴图。

Of course, it would clearly be an extremely laborious task to digitize the 3D geometry and the albedo map of our face.

当然，实现3D影像以及数字化面部无光颜色贴图是一项艰巨的任务。

After taking a photograph, this technique creates two of these albedo maps: one is a complete, low frequency map, which records the entirety of the face, but only contains the rough details.

拍摄照片后，种技术会创造出样两张无光颜色贴图：一张是完整的低频地图，记录整个脸部，包括一些粗略的细节。

The key insight is that we can also do something akin to that here as well — we take this incomplete albedo map, and try to synthesize the missing details.

关键是，我们还可以举一反三，将个不完整的无光颜色贴图尝试合成出缺少的细节部分。

And with this new technique called Deep Opacity Maps, these layers are chosen more wisely, and this way, we can achieve higher quality results with only using 3 layers, and it runs easily in real time.

项新技术就是深度不透明贴图，将些分层的选择更加优化，样一，你需要用3层就获得更高品质的结果，并且种技术运算相当快。

This albedo map means a texture, a colored pattern that describes how our skin reflects and absorbs light.

无光颜色贴图的实质就是纹理，一种有颜色的图案，它描述的是我们的皮肤是如何反射和吸收光线的。

The other albedo map contains finer details, but in return, is incomplete.

另一张无光颜色贴图显示出更微小的细节，却并不完整。

Path tracing is then used to determine direct and indirect lighting for each of these low-resolution objects, and the results are saved into a lightmap on the low-resolution duplicate.

路径追踪然后用于确定些低分辨率对象的直接和间接光照，并将结果保存到低分辨率副本的光照贴图中。

And then built a system that wraps those around a planet and blends them all together.

然后构建了一个系统，将些景观贴图环绕在星球周围，并将它们无缝融合在一起。

As well as a normal map that shows the direction each of the objects and pixels are facing.

以及一个法线贴图，显示每个对象和像素的朝向方向。

Then the lightmap is applied to the high-resolution version of the objects in the scene, creating realistic indirect lighting and shadows on the high-resolution objects.

然后将光照贴图应用于场景中对象的高分辨率版本，从而在高分辨率对象上创建逼真的间接光照和阴影。

To figure it out, we use ray tracing with this simplified screen space 3D representation and bounce the rays off of the lake's pixels using the normal map.

为了弄清楚一点，我们使用光线追踪技术，结合个简化的屏幕空间3D表示，并利用法线贴图将光线从湖泊的像素上反射出去。

For example, in order to build an interstellar battle set in a galaxy far, far away, 3D artists model and texture the spaceships, position them around the scene with lights, a background, and a camera, and then render the scene.

如，为了构建一个设定在遥远星系的星际战斗场景，3D艺术家会建模并贴图飞船，将它们放置在场景中，并配上灯光、背景和摄像机，然后渲染整个场景。

Furthermore, when it comes to video game graphics, there are advanced topics such as shadows, reflections, UVs, normal maps, and more.

此外，在视频游戏图形方面，还有高级主题如阴影、反射、UV贴图、法线贴图等。
