The radial glial cells are disposed in planes perpendicular to the axes of ventricles. The output for the orientation tensor is in the three orthogonal (perpendicular) axes of space. There are six possibilities of choosing the rotation axes for proper Euler angles. Their forces were armed with weapons including sticks, battle axes, old swords and bows. Players can also shoot down projectiles like thrown axes or scythes. Clerics are restricted from using sharp weapons such as swords, axes, etc. This organizes the bed into two cylindrical masses contrarotating on parallel longitudinal axes. It has four quadrants divided by the two crossed axes. Specifically, they are the lines parallel to one of the coordinate axes. The last part of the challenge consisted of swinging blades/axes. The overall result is a lobe pointing along each direction of the primary axes. These are characterized by "three" refractive indices corresponding to three principal axes of the crystal. Combat can be made more effective with weapons like stone axes, spears, and torches. In epicyclic gearing one or more of the gear axes moves. Many rides provide a combination of rotations about several axes.
