relative_rotation: Relative rotation between two rotations

Description

Calculates the relative rotation between two rotations, i.e. the difference from rotation 1 to rotation 2.

Usage

relative_rotation(r1, r2)

Value

list. Euler axes (geographical coordinates) and Euler angles (in degrees)

Arguments

r1, r2

Objects of class "euler.pole". First rotation is r1, followed rotation r2.
