orix 0.10.0

NOTE: This release has been yanked and should not be used. A relevant patch fix (and little else) has been added in 0.10.1.

orix 0.10.0 is a minor release of orix, an open-source Python library for handling orientations, rotations and crystal symmetry

See below, the changelog or the GitHub changelog for all updates from the previous release.

Added

• Support for type hints has been introduced and a section on this topic has been added to the contributing guide.
• Vector3d.pole_density_function() has been implemented which allows for calculation of the Pole Density Function (PDF) and quantification of poles in the stereographic projection.
• Seven methods for sampling unit vectors from regular grids on S2 via orix.sampling.sample_S2().
• Calculation of the Inverse Pole Density Function (IPDF), ie. pole density in the crystal point group fundamental sector, through InversePoleFigurePlot.pole_density_function().
• The orix.measure module has been introduced. The measure module is related to quantification of orientation and vector data.
• Plotting the IPF color key on a created InversePoleFigurePlot is now possible with plot_ipf_color_key().
• Examples gallery to documentation.

Changed

• Moved part of documentation showing plotting of Wulff net and symmetry markers from the tutorials to examples.
• Renamed user guide notebooks to tutorials in documentation.
• Reference frame labels of stereographic projection of Symmetry.plot() from (a, b) to (e1, e2), signifying the standard Cartesian reference frame attached to a crystal.
• Tighten distribution of random orientation clusters in tutorial showing clustering across fundamental region boundaries, to avoid clustering sometimes giving two clusters instead of three.

Removed

• Support for Python 3.6 has been removed. The minimum supported version in orix is now Python 3.7.
• Object3d.check(), Quaternion.check_quaternion() and Vector3d.check_vector(), as these methods were not used internally.
• Deprecated method distance() of Misorientation and Orientation classes, use get_distance_matrix() instead.

Fixed

• Plotting of unit cells works with Matplotlib v3.6, at the expense of a warning raised with earlier versions.

orix 0.9.0.post0

orix 0.9.0.post0 is a post-release of orix, an open-source Python library for handling orientations, rotations and crystal symmetry.

This release is necessary so that the 0.9.0 release is successfully uploaded to Zenodo.

See v0.8.2...v0.9.0.post0 for a complete list of changes.

orix 0.9.0

orix 0.9.0 is a minor release of orix, an open-source Python library for handling orientations, rotations and crystal symmetry.

This version contains many small and some larger changes, including enhancements to existing classes and bug fixes. See the changelog or v0.8.2...v0.9.0 for a complete list of changes.

Notable changes:

• orix.scalar.Scalar has been removed, so the data held by Scalar, like class properties Rotation.angle, Vector3d.azimuth and so on, are returned directly as a numpy.ndarray.
• Creating rotations from Euler angles interprets the angles in the Bunge convention by default, i.e. rotations are transformations from the sample to the crystal.
• Reducing memory usage when computing the misorientation distance matrix, rotation outer products and quaternion-vector outer products have been added via lazy computation with dask.
• The alignment of crystal axes in the package is documented in the user guide.

orix 0.9.0rc2

orix 0.9.0 is a minor release of orix, an open-source Python library for handling orientations, rotations and crystal symmetry.

This version contains many small and some larger changes, including enhancements to existing classes and bug fixes. See the changelog or v0.8.2...v0.9.0rc2 for a complete list of changes.

Notable changes:

• orix.scalar.Scalar has been removed, so the data held by Scalar, like class properties Rotation.angle, Vector3d.azimuth and so on, are returned directly as a numpy.ndarray.
• Creating rotations from Euler angles interprets the angles in the Bunge convention by default, i.e. rotations are transformations from the sample to the crystal.

orix 0.9.0rc1

orix 0.9.0 is a minor release of orix, an open-source Python library for handling orientations, rotations and crystal symmetry.

This version contains many small and some larger changes, including enhancements to existing classes and bug fixes. See the changelog or v0.8.2...v0.9.0rc1 for a complete list of changes.

orix 0.8.2

orix 0.8.2 is a patch release of orix, an open-source Python library for handling orientations, rotations and crystal symmetry.

Changed

• orix.quaternion.Quaternion now relies on numpy-quaternion for quaternion conjugation, quaternion-quaternion and quaternion-vector multiplication, and quaternion-quaternion and quaternion-vector outer products.
• Rounding in functions, e.g. Object3d.unique() and Rotation.unique(), is now set consistently at 12 dp.

Fixed

• Miller.in_fundamental_sector() doesn't raise errors.
• Miller.unique() now correctly returns unique vectors due to implemented rounding.

See the changelog or v0.8.1...v0.8.2 for a complete list of changes.

orix 0.8.1

orix 0.8.1 is a patch release of orix, an open-source Python library for handling orientations, rotations and crystal symmetry.

The patch fixes a few smaller bugs and corrects the following:

• Disorientation angles and dot products returned from Orientation methods angle_with() and dot() and dot_outer() which now calculates the misorientation as other * ~self, instead of the other way around. Disorientation angles (o2 - o1).angle and o1.angle_with(o2) are now the same.
• The inverse indices returned from Rotation.unique(), which now recreate the original Rotation instance.

See the changelog or v0.8.0...v0.8.1 for a complete list of changes.
