Map grains with rotation axis

[hwhouse]

Dear community：

I calculate the grain rotation of each grain during tensile deformation, now i can obtain the Rs(roation axis in sample coordinate) and Rc(rotation axis in crystal coordinate) of each pixel of a grain after deformation, how can i draw the Rs and Rc map of the grain respectively?

Best regards

Hi,
assuming that your axes in specimen coordinates are of type vector3d and those in crystal coordinates are of type Miller you can use a colorcoding such as:

axes_in_specimen_coordinates = vector3d.rand(10) % some random data
cKS =HSVDirectionKey(specimenSymmetry('1'))
rgb = cKS.direction2color(axes_in_specimen_coordinates)

axes_in_specimen_coordinates = Miller.rand(10,crystalSymmetry('222')) % some random data
cKC = HSVDirectionKey(axes_in_specimen_coordinates.CS):
rgb = cKC.direction2color(axes_in_specimen_coordinates);

Have a look at the documentation, for example here: https://mtex-toolbox.github.io/EBSDGROD.html
