You have to build everything out of voxels.

你必须用素构建一切。

The process of guessing how these voxel arrays should look based the input photograph is referred to in the research community as volumetric regression.

根据输入照片猜测这些素阵应该是什么样子的过程在研究领域被称回归。

The authors went for a 3D voxel array, which is essentially a cube in which we build up the face from small, identical Lego pieces.

作者择了一种3D立像素排，上就是一种方块，我们用一些小的、相同的“乐高”碎片来构建面部。

The output is what computer graphics researchers like to call a volumetric representation or a voxel array, which is essentially a large collection of tiny Lego pieces that build up the scene.

计算机图形学研究者把该算法的输出称一种立表示，也就是素的集合，上可看成许多乐高木，堆成了一个场景。

A voxel is like a three-dimensional pixel, but instead of being a flat image square, staying light and colored, it's like a three-dimensional cube in space, with x, y, and z positions.

素就像一个三维像素， 但它不是一个平面图像正方形，保持浅色和彩色， 它就像空间中的三维立方， 具有 x、y 和 z 位置。
