v0.1.11

[0.1.11] - 2023.10.09

Added

• Add sample_texture method from_ODF_mat

v0.1.10

[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.

v0.1.9

[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).

v0.1.8

[0.1.8] - 2021.09.24

Changed

• Validate orientations in visualise_orientations/pole_figure.
• Respect quat_component_ordering in plot_pole_figure

v0.1.7

[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.

v0.1.6

[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

v0.1.5

[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. 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.

v0.1.4

[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.

v0.1.3

[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.

v0.1.2

[0.1.2] - 2020.07.18

Added

• Support generating an ODF from CRC (and CPR) EBSD files (in addition to existing CTF file support).
