A method of SO3TangentVector.

the angle of the rotation the vector describes, or the angle between two vectors

Syntax

omega = angle(v)

The rotational angle, the length.

omega = angle(v1, v2)

The angle between the vectors.

omega = angle(v1, v2, antipodal=True)

Read as axes, at most 90 degree.

Description

The second vectors are brought to the reference and side of the first; the keywords are those of vector3d.angle and need the second vectors.

Input

v1 SO3TangentVector
other SO3TangentVector at the same reference

Output

omega the angles in radians

Signature

SO3TangentVector.angle(self, other=None, **kwargs)
