everyone knows 1,2,3 point perspective, but how does /ic/ deal with distortion?
I try to understand this field of view business.
Would it be accurate to say that the face to the left would be what you'd see in real life if the person sat as a model for you, and you would only see the perspective of a face to the right in real life if it was a giant "attack of the titan" size person?
Field of view is kind of an odd wording for it.
It's really just about perspective and the distance to the object you're looking at.
If you're standing far away from something, there will be little distortion, because the different parts of the thing you're looking at will be roughly the same distance away from you.
For example, if you're looking at a person 10m away from you, the eyes may be 10m and 10.06m away from you, so there will be virtually no distortion. This is why things look odd when you're looking through binoculars, because you're looking at things with very little distortion, almost like a technical drawing (which have absolutely no distortion).
However, the closer something is to you, the greater the relative distance of the various parts of the objects you're looking at will be from your point of view.
If someone is standing face to face with you, the distance of the eyes might be 10cm and 16cm, which is a 60% difference in distance from your points of view. It's similar to looking at two objects that are 10m and 16m away from you, and if you know anything at all about perspective, you know these objects will look like they're different sizes.
In other words, the object closer to you takes up a greater part of your vision, thus will be "larger".
