velocity-adaptive sampling

tn=(dm+(dx-dm)*(vc-vm)/(vx-vm))/vc

y

filter stops

vc=vx

n

There may be other factors

vc=vm

constants(settings):vm - min adaptive velocitydm - sample distance at min velocityvx - max adaptive velocitydx - sample distance at max velocity

variables:var prefixes:v... -velocityt... -time offset to samplingvar suffixes:...c - current...n - next...p - prev...pp - pre-prev
