Dynamic Approximation of Static Quantities (Visual Depth Perception 14)

This Demonstration shows the asymptotic relation between

dθ/dt

and

(binocular disparity) and between

dα/dt

and

(fixate convergence angle). It also shows the motion/pursuit law at the critical time

where it is a better two-dimensional measure of depth than the time zero M/PL or the static formula (based on the symmetric case). The angle slider moves the distractor around a circle where retinal motion is constant. The "node percent"

is the fraction of the eye radius where the node point lies with

n=0

at the center of the eye.
