set_step ( self,  step )

update_transform ( self )

Compute 3 by 4 matrices encoding rotation and translation.

xyz_to_ijk ( self,  xyz )

A matrix ijk corresponds to a point in xyz space. This function maps the xyz point to the matrix index. The returned matrix index need not be integers.

set_cell_angles ( self,  cell_angles )

set_origin ( self,  origin )

ijk_to_xyz ( self,  ijk )

A matrix ijk corresponds to a point in xyz space. This function maps the matrix index to the xyz point.
