# Dynamic Approximation of Static Quantities (Visual Depth Perception 14)

Dynamic Approximation of Static Quantities (Visual Depth Perception 14)

This Demonstration shows the asymptotic relation between and (binocular disparity) and between 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 at the center of the eye.
