Enum Turning 

pub enum Turning {
    Not,
    AboutZ,
    Cross,
    Free,
}

How a joint lets its second frame turn against its first.

Variants

Not

Not at all: the frames’ axes keep where they are to each other.

AboutZ

About the first frame’s z axis, by the joint’s angle.

Cross

About the first frame’s z axis and about the second’s, which are kept square to each other: the cross of a universal joint. How far it is turned is no coordinate: two angles of a cross go singular where it folds over, as Euler angles do (see AGENTS.md, “Degenerate parametrizations”).

Free

Any way about the second frame’s origin. No coordinate either, for the same reason.
