This Demonstration shows the asymptotic relation between
dθ/dt
and
δ
(binocular disparity) and between
dα/dt
and
κ
F
(fixate convergence angle). It also shows the motion/pursuit law at the critical time
t
c
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"
n
is the fraction of the eye radius where the node point lies with
n=0
at the center of the eye.
