Imagine that we have a large database with these geometries and images, and we can search and compare them with arbitrary inputs and outputs.

试想我们有一个很大的图像和几何形状数据库，然后我们可以搜索数据库中的模型并和任意的输入输出进行比较。

This is great, but we said that it supports arbitrary inputs and outputs, which means that we can use the 3D geometry of a chair as an input, and obtain other, similar looking chairs from the database.

这听起来很棒，不过我们说过这个系统支持任意的输入和输出 意思是，我们可以以一个椅子的 3D 几何形状作为输入，得到另一些有相似外观的椅子(来自数据库中的)。
