Statistics Filters (Crystallographic)
This filter identifies all Faces between neighboring Fields that have a Sigma 3 twin relationship. The filter uses the average orientation of the Fields on either side of the Face to determine the misorientation between the Fields. If the axis-angle that describes the misorientation is within a user-defined tolerance, then the Face is flagged as being a twin. After the Face is flagged as a twin, the crystal direction parallel to the Face normal is determined and compared with the misorientation axis. The misalignment of these two crystal directions is stored as the incoherence value for the Face (the value is in degrees).

Type | Default Name | Description | Comment | Filters Known to Create Data |
---|---|---|---|---|
Face | SurfaceMeshFaceLabels | N x 2 Col of signed integer | Quick Surface Mesh (SurfaceMeshing), M3C Surface Meshing (Slice at a Time) | |
Face | SurfaceMeshFaceNormals | N x 3 Col of floats | Generate Triangle Normals Filter (SurfaceMeshing) | |
Face | SurfaceMeshTwinBoundary | boolean value equal to 1 for twin and 0 for non-twin | Find Twin Boundaries (Statistics) | |
Field (Voxel) | AvgQuats | Five (5) values (floats) defining the average orientation of the Field in quaternion representation | Filter will calculate average quaternions for Fields if not already calculated. | Find Field Average Orientations (Statistics) |
Field (Voxel) | FieldPhases | Phase Id (int) specifying the phase of the Field | Find Field Phases (Generic), Read Field Info File (IO), Pack Primary Phases (SyntheticBuilding), Insert Precipitate Phases (SyntheticBuilding), Establish Matrix Phase (SyntheticBuilding) | |
Ensemble (Voxel) | 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) |

Face | SurfaceMeshTwinBoundary | boolean value equal to 1 for twin and 0 for non-twin | |
Face | SurfaceMeshTwinBoundaryIncoherence | Angle in degrees between crystal direction parallel to Face normal and misorientation axis |
