OOF: Finite Element Analysis of Microstructures
OOF2 and Orientation Maps
Version 2.0.4 of OOF2 can import orientation mapping data, such as that generated by Orientation Imaging Microscopy. This allows the orientation of the material at every pixel of the Microstructure to be determined experimentally, rather than being assigned by the user. OOF2 2.0.4 is still a beta release, meaning that it's not thoroughly tested or well documented, and the features may still change. It's being made available so that we can get some feedback from users about what features will be useful.
NOTE to users of 2.0.4a1 and 2.0.4a2: The orientation mapping features are now included automatically. You no longer need to provide the --enable-orientationmap argument to setup.py.
The Microstructure page contains a button called "New from Orientation Map", which makes OOF2 read an orientation data file and creates a Microstructure of the same size as the data in the file. It's also possible to load orientation data into an existing Microstructure using the OrientationMap/Load menu item in the menubar in the main OOF2 window. A Microstructure can only contain one orientation map at a time.
The orientation data file, at the moment, must be in the TSL .ang format or the HKL .ctf format. It is easy to support other formats. Please let us know what you need. Please let us know if the data files are being read correctly.
To tell OOF2 to actually use the orientation map, you must use Materials that contain the OrientationMap property. It is not sufficient to simply load the map into the Microstructure.
It's possible to view the orientation data by creating a new graphics window layer that displays a Microstructure with the "OrientationMap" display method. There are a number of ways provided for converting angles to colors for the display, but no doubt the ones you really want to use are missing. Please let us know what you'd like -- new methods are pretty easy to implement.
OOF2 2.0.4b1 is probably missing a lot of useful features for handling orientation data. Please let us know of any other missing features that you'd find useful.
