Generic Filters (Misc)
This filter will generate colors based on the method developed by C. Schuh and S. Patala for Cubic, Hexagonal, Tetragonal, or Orthorhombic Crystal Structures (currently only cubic high is working)[1]. Orientations are colored by disorientation relative to a reference orientation. The user can enter a reference orientation which is relative to the sample reference frame. The default reference orientation is the sample frame (misorientation from sample frame: 0 degrees about [001]).
The user is required to run a filter that will determine if a voxel should have it's color calculated by generating the GoodVoxels array or an equivalent boolean array. Typically the MultiThreshold Cells or Single Threshold Cells filter is run before this filter with an output array set to GoodVoxels.
The user should be aware of the crystal symmetry (Laue Group and Point Group) of their data. The Filter is only valid for certain point groups within a Laue group (See table below).
With other coloring methods such as IPF bad voxels which result from non-indexed EBSD scans can be colored with a black color (RGB= 0,0,0). Since the Misorientation Coloring scheme uses all possible colors, marking voxels in an image in such a way that the voxels stand out is not possible.
