- Vector3d.get_circle(opening_angle: Union[float, ndarray] = 1.5707963267948966, steps: int = 100) Vector3d #
Get vectors delineating great or small circle(s) with a given
opening_angleabout each vector.
Used for plotting plane traces in stereographic projections.
Opening angle(s) around the vector(s). Default is \(\pi/2\), giving a great circle. If an array is passed, its size must be equal to the number of vectors.
Number of vectors to describe each circle, default is 100.
Vectors delineating circles with the
opening_angleabout the vectors.
A set of
stepsnumber of vectors equal to each vector is rotated twice to obtain a circle: (1) About a perpendicular vector to the current vector at
opening_angleand (2) about the current vector in a full circle.
