State two types of depth cues.
.Monocular depth cues
.Binocular depth cues
Define monocular depth cues.
.It allows judgement of depth and distance using one eye.
Define binocular depth cues.
.It allows judgment of depth and distance using both eyes.
Explain the difference between monocular and binocular depth cues.
.Monocular- allows judgement of depth and distance using one eye
.Binocular-allows judgment of depth and distance using both eyes.
Identify types of monocular depth cues.
Height in plane.
Relative size.
Occlusion.
Linear perspective
Outline height in plane.
.When objects that are higher up in the visual field appears to be further away.
Outline relative size.
When objects appear smaller in the visual field than known objects of a similar size.
Outline occlusion.
The objects that are behind or obscured by other objects are further away.
Outline Linear perspective .
.Lines that are parallel appear to get closer together and come to a point in the distance. Showing that points where the lines meet is further away
