3 reasons to have depth perception
|
- detection - discrimination - identification
|
|
Why is depth perception difficult
|
- the world is 3D (our initial visual representation is 2D but somehow we recover the 3D (depth))
|
|
How do we see depth?
|
Cues helps us solve the problem
|
|
Types of cues for depth and distance
|
- monocular- binocular
|
|
6 types of static (pictorial) cues
|
- occlusion - ariel (atmospheric) perspective - linear perspective - texture - shading - size
|
|
Closer
objects partly block the view of more distant objects
|
Occlusion
|
|
How does occlusion enable us to a perception of depth?
|
–you
see the occluding object as closer than the occluded object).
|
|
–also
enables us to complete and recognize
objects.
|
Occlusion
|
|
–is
closely related to other perceptual phenomena such as transparency and illusory
contours.
|
Occlusion
|
|
Occlusion also is related to __ __
|
Illusory contours
|
|
More distant objects are perceived less
clearly than closer objects.
|
Aerial perspective
|
|
–The further
the light must travel to reach the
eye, the ___ likely that light will be interfered with in some way by matter.
|
Less
|
|
–Aerial
perspective sometimes is called ... ... because the effect is due to the
atmosphere interfering with light.
|
Atmospheric perspective
|
|
•Lines that are parallel in the real
world appear to converge in a drawing.
|
Linear perspective
|
|
–The
greater the distance, the __ the convergence.
|
Greater
