6.7.0 (2022-12-28)

Features

  • Add Circle.intersect_circle method.

6.6.0 (2022-11-20)

Features

  • Add Vector.angle_signed_3d method.

6.5.0 (2022-09-05)

Features

  • Add LineSegment class.

Docs

  • Add plot of Cylinder-Line Intersection to the gallery.

6.4.1 (2022-06-21)

Fixes

  • Update the dimension value of a slice, instead of using the value of the original array.
  • Fix the output radius of Cylinder.to_mesh.

6.4.0 (2022-04-07)

Features

  • Add Plane.project_line method to project a line onto a plane.

6.3.0 (2022-02-26)

Features

  • Add Circle.best_fit method to fit a circle to 2D points.
  • Add area_signed function to compute the signed area of a polygon using the shoelace algorithm.

6.2.1 (2022-01-08)

Fixes

  • Allow for versions of importlib-metadata above 1.

6.2.0 (2021-10-06)

Features

  • Add infinite keyword argument to Cylinder.intersect_line with a default value of True. Now the line can be intersected with a finite cylinder by passing infinite=False.

Fixes

  • Fix the return type hint of Plane.intersect_line (from Plane to Point).

6.1.1 (2021-09-11)

Fixes

  • Add code to skspatial.__init__.py to keep the __version__ attribute in sync with the version in pyproject.toml.

6.1.0 (2021-07-25)

Features

  • Add lateral_surface_area and surface_area methods to Cylinder.

Improvements

  • Remove unnecessary np.copy from Circle.intersect_line.
  • Complete the docstring for Line.distance_point.

6.0.1 (2021-03-25)

Fixes

  • Wrap filterwarnings("error") in a catch_warnings context manager, in __BaseArray.__new__(). Now the warning level is reset at the end of the context manager.

6.0.0 (2021-03-21)

Breaking changes

  • Require NumPy >= 1.20 to make use of the static types introduced in 1.20. Now numpy-stubs doesn't need to be installed for static type checking.
  • Move tests outside of package, and move package under src directory. This ensures that tox is running the tests with the installed package.
  • Switch from setup.py to pyproject.toml.
  • Add more ValueErrors for clarity, such as "The lines must have the same dimension" ValueError in Line.intersect_line.

Features

  • Add Cylinder class.
  • Add Vector.different_direction method.
  • Add Sphere.best_fit method.

Refactoring

  • Delete Vector.dot method. The dot method is already inherited from NumPy.

5.2.0 (2020-12-19)

  • Add keyword arguments to Plane.best_fit and Line.best_fit. These are passed to np.linalg.svd.

5.1.0 (2020-12-07)

  • Edit type annotations to support Python 3.6.
  • CI now tests Python versions 3.6-3.9.

5.0.0 (2020-11-23)

  • Return regular ndarray from inherited NumPy functions, e.g. vector.sum() - This prevents getting spatial objects with disallowed dimensions, such as a 0-D vector. - This fixes broken examples in the README.
  • Test README examples with doctest.
  • Replace tox with Docker. - Docker multi-stage builds are a convenient feature for isolating test environments.
  • Organize requirements into multiple files. - This makes it easy to install only what's needed for each test environment.

4.0.1 (2020-02-01)

  • Fix to replace Python 3.6 with 3.8 in the setup.py file.

4.0.0 (2020-02-01)

  • Drop support for Python 3.6 (this allows for postponed evaluation of type annotations, introduced in Python 3.7).
  • Add Triangle class.

3.0.0 (2019-11-02)

  • Add Points.normalize_distance method to fit points inside a unit sphere.
  • Change Points.mean_center to only return the centroid of the points if specified. This allows for chaining with other transformations on points, like normalize_distance.
  • Add to_array method to convert an array based object to a regular NumPy array.

2.0.1 (2019-08-15)

  • Use installation of numpy-stubs from its GitHub repository instead of a custom numpy stubs folder.
  • Introduce 'array_like' type annotation as the union of np.ndarray and Sequence.
  • Add py.typed file so that annotations can be used when scikit-spatial is installed.

2.0.0 (2019-07-20)

  • Replace some NumPy functions with ones from Python math module. The math functions are faster than NumPy when the inputs are scalars. The tolerances for isclose are now rel_tol and abs_tol instead of rtol and atol. The math.isclose function is preferable to np.isclose for three main reasons:

    • It is symmetric (isclose(a, b) == isclose(b, a)).
    • It has a default absolute tolerance of zero.
    • It does not correlate the absolute and relative tolerances.

  • Add type annotations to methods and run mypy in Travis CI.

  • Add round method to array objects (Point, Points and Vector). Now a Vector is returned when a Vector is rounded.

  • Add methods to return coordinates on the surface of a Plane or Sphere. The coordinates are used for 3D plotting.

  • Improve Plane plotting so that vertical planes can be plotted.

1.5.0 (2019-07-04)

  • Add Circle and Sphere spatial objects.
  • Add scalar keyword argument to Vector plot methods.
  • Improve plotting of Plane. The x and y limits now treat the plane point as the origin.

1.4.2 (2019-06-21)

  • Extra release because regex for version tags was incorrect in Travis.

1.4.1 (2019-06-21)

  • Extra release because Travis did not deploy the last one.

1.4.0 (2019-06-21)

  • Add functions plot_2d and plot_3d to facilitate plotting multiple spatial objects.
  • Change _plotting module name to plotting, because it now contains some public functions.

1.3.0 (2019-06-19)

  • Remove dpcontracts as a dependency. The contracts were causing performance issues.
  • Add 'dimension' attribute to all spatial objects.
  • Add Vector.angle_signed method.
  • Add Line.from_slope method.

1.2.0 (2019-06-11)

  • Move tests into skspatial directory. This allows for importing custom hypothesis strategies for testing other projects.
  • Drop support for Python 3.5 (matplotlib requires >= 3.6).

1.1.0 (2019-05-04)

  • Add methods for 2D and 3D plotting.
  • Rename private modules and functions to include leading underscore.

1.0.1 (2019-03-29)

  • Support Python versions 3.5-3.7.

1.0.0 (2019-03-26)

  • Change Vector and Point to be subclasses of the NumPy ndarray.
  • Change all spatial objects to accept array_like inputs, such as a list or tuple.
  • Add the Points class to represent multiple points in space. This is also an ndarray subclass.
  • The dimension of the objects is no longer automatically set to 3D. Points and vectors can be 2D and up.

0.1.0 (2019-02-27)

  • First release on PyPI.
