If you know the shape of your Field of View and you know the size and location of a point on screen (Near plane), you can extrapolate what size the object should be at a given distance when you scale proportionally. You can calculate this by assuming that your Field of View is like a pyramid with a square base, where the point is at your eye (or camera) and the pyramid is aligned to the direction you are looking. ![]() It's all about trigonometry (calculating triangles). The basic idea is that as things get further away, they get smaller.
