rotates an odf with specimen symmetry into its symmetry axes
centerSpecimen(odf,center) tries to find the normal vectors of orthorhombic symmetry for the x mirror and y mirror plane and calculates an rotation needed to rotate the odf back into these mirror planes. the routine starts with a look around grid for a given center (default xvector) to find a starting value for newton iteration.
Syntax
Input
odf | SO3Fun |
v0 | vector3d initial guess for a symmetry axis (default xvector) |
Output
odf | rotated SO3Fun |
rot | rotation such that rotate(odf_out,r) = odf_in |
v1,v2 | normal vector of the two fold symmetry axes |
Options
SO3Grid | a SO3Grid where the SO3Fun is evaluated on |
delta | specifies the opening angle for the initial search grid around input center |
resolution | specifies the resolution for the initial search grid |
silent | don't verbose number of initial axes and the newton iteration |
Fourier | use Fourier coefficients as objective function |
