One of the difficulties of doing passthrough right is the positional difference between cameras on the outside of a headset and the eyes of the user. So the image has to go through a distortion process. On the Quest Pro and [[Quest 3]], this uses a neural network. Other devices potentially also use a neural network.

It is possible to use a [[light field camera]] to capture an image and reproject it at a different transform.

It is also possible to have a camera offset from the headset and facing the headset, and put a mirror on the headset.
