# Change Log
## [0.1.11] - 2023.10.09
### Added
- Add `sample_texture` method `from_ODF_mat`
## [0.1.10] - 2022.04.12
### Added
- Add options `colourbar_limits` and `use_one_colourbar` to `plot_pole_figure.m` snippet.
### Fixed
- Sample a maximum of 1000 orientations for the pole figure in `write_orientations_from_VE_response` input mapper.
## [0.1.9] - 2021.12.20
### Added
- Add task `sample_orientations` with methods `from_CTF_file` and `from_CRC_file`. This is for randomly sampling `N` orientations directly from the EBSD data. Similar to the `sample_texture` task, but an intermediate ODF is not constructed.
- Support sampling orientations from a fibre ODF that is parametrised by a crystal direction `fibre_crystal_dir` (e.g. `[1, 0, -1, 0]`) and a parallel sample direction `fibre_specimen_dir` (`x`, `y`, or `z`).
- Support sampling orientations from a unimodal ODF that is parametrised by a single Euler angle triplet `modal_orientation_euler` (in Bunge/degrees/MTEX hexagonal unit cell alignment `y // b`).
- Option to either plot pole figures with filled contours or with markers using the new boolean option `use_contours` to the task: `visualise_volume_element_response/pole_figure`. If using markers, the markers will be coloured by IPF colouring. The IPF reference direction is the `z`-direction by default, but can be specified with the new option `IPF_reference_direction`.
### Fixed
- Fix `visualise_volume_element_response/pole_figure`. Users can now plot pole figures for multiple increments and for selected phases. A pre-requisite for this is that two `field_data` items are specified in the `output_map_options` of the `simulate_volume_element_loading` task:
- `field_name: phase`
- `field_name: O` (orientations).
## [0.1.8] - 2021.09.24
### Changed
- Validate orientations in `visualise_orientations/pole_figure`.
- Respect `quat_component_ordering` in `plot_pole_figure`
## [0.1.7] - 2021.03.21
### Changed
- Add option to rotate EBSD data in snippets `get_ODF_from_CRC_file` and `get_ODF_from_CTF_file`.
## [0.1.6] - 2021.01.19
### Added
- Support "fibre" ODF components in snippet `get_model_ODF.m`
- Add input mapper for task `visualise_volume_element_response` with method `texture_pole_figure`.
### Changed
- Account for `euler_degree` boolean specification in orientations JSON file.
- Scale vector part of quaternions in `plot_pole_figure` snippet by -1 if P-constant is +1.
- Change visualise orientations snippet to plot contours
## [0.1.5] - 2021.01.10
### Added
- Add new tasks for generating orientations that bypass exporting/importing ODFs due to issues with how [MTEX currently handles this](https://github.com/mtex-toolbox/mtex/issues/659). These tasks are: `sample_texture` with methods: `from_model_ODF`, `from_CTF_file` and `from_CRC_file`. Previously, this would have been achieved with two tasks `get_model_texture`/`estimate_ODF` and then `sample_texture`.
- Add ability to generate an ODF in `sample_texture/from_model_ODF` task using multiple ODF components.
- Add `visualise_orientations/pole_figure` task to plot sampled orientations on a pole figure in MTEX.
## [0.1.4] - 2020.12.10
### Fixed
- Fix output mapper functions `parse_orientations` and `parse_MTEX_ODF_file` for cases where the files have only one row of data. Now we use the `ndmin=2` argument of `numpy.loadtxt` to ensure arrays of consistent dimensions are returned.
## [0.1.3] - 2020.08.18
### Added
- Support specifying orientation coordinate system, which can be used to correctly align, within the model, the textures with respect to e.g. RD/TD/ND.
## [0.1.2] - 2020.07.18
### Added
- Support generating an ODF from CRC (and CPR) EBSD files (in addition to existing CTF file support).
## [0.1.1] - 2020.07.01
### Added
- Add `fibre` method to `get_model_texture` task.
- Add `random` method to `get_model_texture` task.
### Changed
- Use `orientation.byMiller` in `get_unimodal_ODF.m`
## [0.1.0] - 2020.06.09
- Initial release.
