relative_rotation function

Relative rotation between two rotations

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

relative_rotation(r1, r2)

Arguments

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

Returns

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

Examples

a <- euler_pole(90, 0, angle = 45)
b <- euler_pole(0, 0, 1, geo = FALSE, angle = -15)
relative_rotation(a, b)
relative_rotation(b, a)
