Every GAD object has an intrinsic orientation, which is defined through its principal direction (key Axis1), a first perpendicular direction (key Axis2) and a second perpendicular direction forming a RHS coordinate system.

This orientation can be described in form of the Euler angles required to rotate the cartesian coordinate system into the intrinsic one. Thus, for an intrinsic coordinate system described through Axis1 = (1,0,0) and Axis2 = (0,1,0), all Euler angles would be zero.

The local orientation of a voxel is needed for some simulations (e.g. in ElastoDict) and can be stored in a 3D field that contains the three Euler angles for each voxel.

The Create GOF Orientation Image command creates this volume field. This command requires no input parameters, so there are no parameters to be set.

When the command is run, no (result) files are created. The created field is available in GeoDict as a volume field named GADOrientation.gof.

By a right click on the GADOrientation.gof line, the context menu allows to save the index image as .gof file.
