Struct FreeMotion 

pub struct FreeMotion {
    pub about: Point,
    pub radius: f64,
    pub rotation: Vector,
    pub translation: Vector,
}

A rigid motion pairs do not hold: a turn at FreeMotion::rotation about an axis through FreeMotion::about, with a slide of about at FreeMotion::translation.

Scaled so that |rotation| · radius and |translation| have a unit root sum of squares. Where the motions free are a subspace, they are the basis of it that splits rotation from translation as far as it allows: a selection free to slide and to spin reports pure slides and a pure spin.

Fields

about: Point

The kept samples’ centroid, once moved.

radius: f64

The kept samples’ RMS distance from FreeMotion::about.

rotation: Vector

The angular velocity: the axis’s direction, times the rate.

translation: Vector

The velocity of FreeMotion::about.
