mrdja.matplot3d.draw_circle

mrdja.matplot3d.draw_circle(center: ndarray = array([0, 0, 0]), radius: float = 1, normal: ndarray = array([0, 0, 1]), color: str = 'red', alpha: float = 0.5, ax=None)

Draws a circle in 3D space.

Parameters:

• center (numpy.ndarray) – A 3x1 numpy array containing the center of the circle.

• radius (float) – The radius of the circle to draw.

• normal (numpy.ndarray) – The normal vector of the circle.

• color (str) – The color of the circle to draw.

• style (str) – The style of the circle to draw.

• ax (matplotlib.axes._subplots.Axes3DSubplot) – The matplotlib ax object to draw on.

Returns:

The ax object.

Return type:

matplotlib.axes._subplots.Axes3DSubplot

Example:

>>> import mrdja.matplot3d as plt3d
>>> import numpy as np
>>> center = np.array([0, 0, 0])
>>> radius = 1
>>> normal = np.array([0.5, 0.3, 0.8]) / np.linalg.norm(np.array([0.5, 0.3, 0.8]))
>>> plt3d.draw_circle(center, radius, normal, color="blue", alpha=0.2)
