IO (Input)
This Filter reads from the .h5ebsd file that was generated with the Import Orientation File(s) to H5EBSD Filter.
The user is solely responsible for knowing any sample reference frame transformations, crystal reference frame transformations and how the Euler angles are represented in the file. DREAM.3D provides historically correct transformations from a few of the EBSD manufacturers under the assumption that the EBSD instrument has been setup according to their guidelines. The user is strongly encouraged to discuss these topics with the person(s) who were responsible for collecting the data. For example the IPF images presented below were generated from an H5Ebsd file that was generated using a CTF file. The difference is that the Incorrect image did not correctly select the Angle Representation combo box on the filter's user interface. The Euler angles were actually in degrees but were treated as if the values were in radians. The correct image is on the right.
If the user does not want the Read H5Ebsd filter to perform any transformations then the checkbox can be unchecked and the user can manually perform any desired transformations by inserting the appropriate filters into the pipeline. The suggested filters are:
