There are several variations of monocular cues including: |
Interposition
(overlapping) - when the first object is placed over a second object,
the first object appears closer than the second, which is partially blocked
Relative
Height - the object closer to the horizon is perceived as farther away,
and the object further from the horizon is perceived as closer
Familiar Size - when an object is familiar to us, our brain compares
the perceived size of the object to this expected size and thus acquires
information about the distance of the object
Texture
Gradient - all surfaces have a texture, and as the surface goes into
the distance, it becomes smoother and finer. This can be shown by the animation
below - as the rectangles change in dimension they appear to project into
the screen.
Shadow
- objects don’t usually allow light to pass through and therefore cast
a shadow. Some general rules for this phenomenon are:
with
one source of light, all shadows lie in same direction
with an object on the ground, the shadow appears on the other side of the
source
with a hole in the ground, the shadow appears on the same side as the source
the
object covered by the shadow is perceived to be further away then the object
in the light
