Find Neighbor Slip Transmission Metrics

Group (Subgroup)

Statistics (Crystallographic)

Description

This Filter calculates a suite of slip transmission metrics that are related to the alignment of slip directions and planes across Feature boundaries. The algorithm for calculation of these metrics is as follows:

  1. Get the average orientation of the Feature
  2. Get the Feature's list of neighboring Features
  3. Get the average orientation of each neighboring Feature
  4. Calculate metrics given by equations in slip transmission metrics
  5. Store metrics in lists for the Feature
  6. Repeat for all Features

Note: The transmission metrics are calculated using the average orientations for neighboring Features and not the local orientation near the boundary. Also, the metrics are calculated twice (i.e., when Feature 1 has neighbor Feature 2 and when Feature 2 has neighbor Feature 1) because the direction across the boundary between the Features affects the value of the metric.
