Merge Twins¶
Group (Subgroup)¶
Reconstruction (Grouping)
Description¶
THIS FILTER ONLY WORKS ON CUBIC-HIGH (m3m) Laue Classes.
This Filter groups neighboring Features that are in a twin relationship with each other (currently only FCC σ = 3 twins). 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 Elements. The user can specify a tolerance on both the axis and the angle that defines the twin relationship (i.e., a tolerance of 1 degree for both tolerances would allow the neighboring Features to be grouped if their misorientation was between 59-61 degrees about an axis within 1 degree of <111>, since the Sigma 3 twin relationship is 60 degrees about <111>).
Parameters¶
| Name | Type | Description |
|---|---|---|
| Axis Tolerance (Degrees) | float | Tolerance allowed when comparing the axis part of the axis-angle representation of the misorientation |
| Angle Tolerance (Degrees) | float | Tolerance allowed when comparing the angle part of the axis-angle representation of the misorientation |

Required Objects¶
| Kind | Default Name | Type | Component Dimensions | Description |
|---|---|---|---|---|
| Feature Attribute Array | NonContiguousNeighbors | List of int32_t | (1) | List of non-contiguous neighbors for each Feature. Only needed if Use Non-Contiguous Neighbors is checked |
| Feature Attribute Array | NeighborList | List of int32_t | (1) | List of neighbors for each Feature |
| Element Attribute Array | FeatureIds | int32_t | (1) | Specifies to which Feature each Element belongs |
| Feature Attribute Array | Phases | int32_t | (1) | Specifies to which Ensemble each Feature belongs |
| Feature Attribute Array | AvgQuats | float | (4) | Specifies the average orientation of the Feature in quaternion representation |
| Ensemble Attribute Array | CrystalStructures | uint32_t | (1) | Enumeration representing the crystal structure for each Ensemble |
Created Objects¶
| Kind | Default Name | Type | Component Dimensions | Description |
|---|---|---|---|---|
| Element Attribute Array | ParentIds | int32_t | (1) | Specifies to which parent each Element belongs |
| Attribute Matrix | NewFeatureData | Feature | N/A | Created Feature Attribute Matrix name |
| Feature Attribute Array | ParentIds | int32_t | (1) | Specifies to which parent each Feature belongs |
| Feature Attribute Array | Active | bool | (1) | Specifies if the Feature is still in the sample (true if the Feature is in the sample and false if it is not). At the end of the Filter, all Features will be Active |
