Find Average C-Axis Orientations

Group (Subgroup)

Statistics (Crystallographic)

Description

This Filter determines the average C-axis location of each Feature by the following algorithm:

  1. Gather all Elements that belong to the Feature
  2. Determine the location of the c-axis in the sample reference frame for the rotated quaternions for all Elements
  3. Average the locations and store as the average for the Feature

Note: This Filter will only work properly for Hexagonal materials. The Filter does not apply any symmetry operators because there is only one c-axis (<001>) in Hexagonal materials and thus all symmetry operators will leave the c-axis in the same position in the sample reference frame. However, in Cubic materials, for example, the {100} family of directions are all equivalent and the <001> direction will change location in the sample reference frame when symmetry operators are applied.
