The eye can be anywhere, zNear is the distance from the camera clipping will take place.

whatever you point at, the distance wont make a difference because the direction its pointing in is normalised.

Are you meaning to draw the UI with the camera in a perspective projection and not an orthographic one?

Sir, e^iπ + 1 = 0, hence God exists; reply!
