You have to build everything out of voxels.

用体素构建一切。

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

根据入照片猜测这些体素阵列应该是什么样子过程在研究领域被称为体积回归。

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立体像素排列，本质上就是一种方块，我们用一些小、相同“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出称为一种立体表示，也就是体素集合，本质上可看成许多乐高积木，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.

体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， 它就像空间中三维立方体， 具有 x、y 和 z 位置。
