periodic 

<h:div class="summary">Is the axis periodic.</h:div>
<h:div class="description">Any or all of the axes may be periodic or aperiodic. An example could be a surface where 2 periodic axes (not necessarily orthogonal) are used to describe the coordinates in the surface, perhaps representing lattice vectors of a 3D crystal or 2D layer. The third vector is orthogonal and represents coordinates normal to the surface. In this case only the direction, not the magnitude of the vector is important.</h:div>
