text: CellViewer allows to visualize the sample material in four modes widely used in material research:
  * 3D model of atomic structure (direct space),
  * simulated diffraction pattern (reciprocal space),
  * stereographic projection (projection of 3D space of crystallographic planes and directions to 2D),
  * inverse pole figure (defined part of stereographic projection).
  Graphical user interface provides user with two interactive views side by side. These views can display arbitrary combination of the four aforementioned visualization modes allowing to perceive their mutual relations. For instance, rotation of the atomic structure in direct space leads (if set so) to an instant update of the simulated diffraction pattern. If any diffraction spot is selected, corresponding crystallographic planes are shown in the unit cell etc. Such interconnections are implemented for each pair of the four available visualization modes. The electronic visualization allows to simplify understanding of widely used, yet less intuitive representations such as the inverse pole figure. For instance by drawing the coloured triangle of the inverse pole figure into the stereographic projection or to the more intuitive 3D atomic structure.
