Package edu.wpi.first.math.geometry

Class Twist3d

java.lang.Object
edu.wpi.first.math.geometry.Twist3d
public class Twist3d
extends Object
A change in distance along a 3D arc since the last pose update. We can use ideas from differential calculus to create new Pose3d objects from a Twist3d and vice versa.

A Twist can be used to represent a difference between two poses.
