Do you remember the texture synthesis methods that we discussed earlier in the series?

还记得我们之前在某个系列中讨论过的纹理合成的方法吗？

There are also some comparisons against PatchMatch, one of the landmark techniques for texture synthesis that we have also talked about in an earlier episode.

这里还将其与我们之前所接触到的不同于 PatchMatch 的纹理合成标记技术进行了对比。

Note that we cannot just perform this texture synthesis in 2D like we do for images, because as we project the result to a 3D model, it introduces severe distortions to the displacement patterns.

需要注意的是，我们无法像在二维图像里一样做这种纹理合成。因为当我们把合成的结果投影到三维模型上时，会使置换表面纹理产生严重的失真。

This extension is also capable of texture synthesis, which means that we give it a small image patch that shows some sort of repetition, and it tries to continue it indefinitely in a way that seems completely seamless.

这项扩展还可以被用在纹理合成方面，这意味着我们可以输入一小块图像，用来表示某种可重复的纹理，之后这种算法会尝试把这一小块纹理无限扩展，并且看起来完全无缝。
