rotate_grains(
    dfMerged,

    misorientation,

    ref_or,
    ref_id,
    ref_cols_ids
)

Given a pandas DataFrame with Euler angles phi1, Phi, and phi2, rotate each grain voxel by the specified misorientation rate

Args:

  • dfMerged: (pandas DataFrame) DataFrame containing at least, X (m), Y (m), Z (m), phi1, Phi, and phi2
  • gids: (list of int) list of grain IDs contained within dfMerged to which to apply the misorientations
  • misorientation: (float) misorientation rate (angle/meter) in the same angular units as phi1, with standard for ExaCA being degrees
  • update_ids: (bool) whether to update the IDs of each voxel to match to closest ID to their new orientation
  • ref_or: (numpy array) (N, 3) array of phi1, Phi, phi2 of the reference orientations, with default ExaCA being N=10000
  • ref_id: (numpy array) (N, 1) array of Reference ID of the reference orientations, with default ExaCA being N=10000
  • ref_cols_ids: (list of ints) array of column indices for phi1, Phi, and phi2 in dfMerged
