Question

If you close one eye, you will still be able to use ________ as a depth cue, but you will not be able to use ________ as a depth cue.

Answer 1

The appropriate response is texture gradient; disparity. Texture gradient is the contortion in measure which nearer objects have contrasted with objects more distant away. It likewise includes groups of items seeming denser as they move more remote. Whereas, disparity is the distinction in picture area of a object seen by the left and right eyes, coming about because of the eyes' even division.
