How to get the curvature of the trajectory？

[hxxxxxian]

Hi, I want to get the movement track of a point, I can get the speed of each movement of the point in onAnimateEndEvent, but how to get the acceleration? Is there any way to know the curvature of this trajectory?

Hi @hxxxxxian

Acceleration can be interpolated from velocity in time: a(t) = ( v(t)-v(t-dt) ) / dt
Regarding the trajectory curvature, this can not be directly recovered but you can easily get it by tracking the positions of your object at the different time steps.
