Introduction

This package allows to compute the best fit circle given points in three-dimensional space.

Installation

The package can be installed with pip.

$ pip install circle-fitting-3d

Example Usage

>>> from circle_fitting_3d import Circle3D

>>> circle_3d = Circle3D([[3, 0, 0], [0, 3, 0], [0, 0, 3]])

>>> circle_3d.center
Point([1., 1., 1.])

>>> circle_3d.radius
2.449489742783178

The circle and points can be plotted as follows (plot created using the example_1.py script located in the examples folder):

>>> import matplotlib.pyplot as plt
>>> fig = plt.figure()
>>> ax = fig.add_subplot(111, projection="3d")
>>> circle_3d.plot(ax)
