Question 12

Depth Cues

Answer 12

• Stereopsis: The two images of our eyes are combined to produce a single 3D experience
• Accommodation/focus: Muscular process that shapes the lens in our eyes so we can create sharply focussed images. We unconsciously use information from these muscles to provide depth information

• Light and shade: an object with attendant shadow improves the sense of depth

• Linear perspective/height in the horizontal plane: Distant objects appear higher than nearby objects

• Motion parallax: In a moving train, objects nearby (a pole or something) seem to flash past very quickly while a distant building moves much slower

• Occlusion/overlap: An object placed over one another seems to appear closer

• Relative size/familiarity: smaller objects are usually seen as further away

• Texture gradient: Textured surfaces appear to be closer; irregularities tend to be smoothed over distance
