要将平面照渲染成模型，该软件首先对照片进行比较，从而计算出每张照片是在哪个位置拍的。

To make a model from the initial snapshots, the software first compares the photos to work out where in 3-d space they were taken from.

“我们还需要从立体效果图中计算出物体的实际距离，”Stollnitz说，“然后比较这些物体如何出现在不同的平面照中。”

"We also have to calculate the actual depth of objects from the stereo effect," says Stollnitz, "comparing how they appear in different photos."
