Find Cell Quaternions

Group (Subgroup)

Generic Filters (Crystallography)

Description

This filter determines the quaternions for each Cell, given the Euler angles for the Cell. The quaternions calculated are rotated such that they all lie within the Fundamental Zone (FZ) nearest to the origin of orientation space for the crystal structure of the Cell's phase. The FZ is the region of orientation space that contains general positions on which the symmetry operations of the structure cannot operate to generate other positions within the region that are symmetrically equivalent.

Parameters

None

Required DataContainers

Voxel

Required Arrays

Type Default Name Description Comment Filters Known to Create Data
Cell CellEulerAngles Three (3) angles (floats) defining the orientation of the Cell in Bunge convention (Z-X-Z) 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), Match Crystallography (SyntheticBuilding)
Cell CellPhases Phase Id (int) specifying the phase of the Cell 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), Pack Primary Phases (SyntheticBuilding), Insert Precipitate Phases (SyntheticBuilding), Establish Matrix Phase (SyntheticBuilding)
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)

Created Arrays

Type Default Array Name Description Comment
Cell Quats Five (5) values (floats) that specify the orientation of the Cell in quaternion representation The first value is a dummy value, so each Cell has quat = {dummy, q1, q2, q3, q4} - where q1, q2, and q3 contain the axis information and q4 contains the angle information of the quaternion
