Group MicroTexture Regions (C-Axis Misorientation)

Group (Subgroup)

Reconstruction Filters (Grouping)

Description

This Filter groups neighboring Features that have c-axes aligned within a user defined tolerance. The algorithm for grouping the Features is analogous to the algorithm for segmenting the Features - only the average orientation of the Features are used instead of the orientations of the individual Cells and the criterion for grouping only considers the alignment of the c-axes. The user can specify a tolerance for how closely aligned the c-axes must be for neighbor Features to be grouped.

NOTE: This filter is intended for use with Hexagonal materials. While the c-axis is actually just referring to the <001> direction and thus will operate on any symmetry, the utility of grouping by <001> alignment is likely only important/useful in materials with anisotropy in that direction (like materials with Hexagonal symmetry).

Type Default Name Description Comment Filters Known to Create Data
Cell FeatureIds Ids (ints) that specify to which Feature each Cell belongs. Values should be present from segmentation of experimental data or synthetic generation and cannot be determined by this filter. Not having these values will result in the filter to fail/not execute.

Feature Volumes
Feature AvgQuats Four (4) values (floats) defining the average orientation of the Feature in quaternion representation Filter will calculate average quaternions for Features if not already calculated. Find Feature Average Orientations (Statistics)
Ensemble CrystalStructures Enumeration (int) specifying the crystal structure of each Ensemble/phase (Hexagonal=0, Cubic=1, Orthorhombic=2) Values should be present from experimental data or synthetic generation and cannot be determined by this filter. Not having these values will result in the filter to fail/not execute. Read H5Ebsd File (IO), Read Ensemble Info File (IO), Initialize Synthetic Volume (SyntheticBuilding)

Type Default Name Description Comment
Feature Active Boolean value specifying if the Feature is still in the sample (1 if the Feature is in the sample and 0 if it is not). At the end of the filter, all Features will be "Active" as the "Inactive" Features will have been removed.
Feature ParentIds List of grouped microtexture region Features.
Cell ParentIds List of grouped microtexture region Cells.
