Detailed Description

Function Documentation

reduce()

Transform Symmetry3D::reduce ( const Transform &  t3d, int  n = 0  ) const

virtual

A function that will reduce an orientation, as characterized by Euler anges, into a specific asymmetric unit.

Default behavior is to map the given orientation into the default asymmetric unit of the symmetry (n=0). This is a concrete implementation that works for all symmetries, relying on a concrete instance of the get_asym_unit_triangles function

Parameters

t3d	a Transform characterizing an orientation
n	the number of the asymmetric unit you wish to map the given orientation into. There is a strong relationship between n and to Symmetry3D::get_sym

Returns

the orientation the specified asymmetric unit (by default this is the default asymmetric unit of the symmetry)

Definition at line 974 of file symmetry.cpp.

{
        // Determine which asym unit the given asym unit is in
        int soln = in_which_asym_unit(t);
 
        // This should never happen
        if ( soln == -1 ) {
                cout << "error, no solution found!" << endl;
//              throw;
                return t;
        }
 
        // Get the symmetry operation corresponding to the intersection asymmetric unit
        Transform nt = get_sym(soln);
        // Transpose it (invert it)
        nt.invert();
        // Now we can transform the argument orientation into the default asymmetric unit
        nt  = t*nt;
        // Now that we're at the default asymmetric unit, we can map into the requested asymmunit by doing this
        if ( n != 0 ) {
                nt = nt*get_sym(n);
        }
        // Done!
        return nt;
 
}
