Motion Parallax versus Depth, 2D (Visual Depth Perception 12)

relative depth

0.5

This Demonstration lets you move the relative distance between

0

and

1

and uses the formulas below to find the fixate distance

f

and pursuit rate

dα/dt

, keeping the motion

dθ/dt=1°

.

The program computes the binocular disparity of a fixed observer at the

t=0

position. Notice that

B.D.≈dθ/dt

.
