Apparent

a footstool at your feet. a monolith at the door. the same cube.

drag a cube down a hallway; pinned to one screen size, so the depth you release it at sets how big it reads

A far object and a close one can cast the same image, so your brain judges size from context: a floor, a doorway, a crate to compare against. The cube stays one size on screen, so depth alone decides how big it reads.

Concepts: depth, perception, scale.
