-While Quaternions are quite difficult to fully understand, there are an exceeding number of convenience methods to allow you to use them without having to understand the math behind it. Basically, these methods involve nothing more than setting the Quaternion's x,y,z,w values using other means of representing rotations. The Quaternion is then contained in xref:jme3/advanced/spatial.adoc[Spatial] as its local rotation component.
