Examples of com.jme3.math.Quaternion

com.jme3.math.Quaternion
Quaternion defines a single example of a more general class of hypercomplex numbers. Quaternions extends a rotation in three dimensions to a rotation in four dimensions. This avoids "gimbal lock" and allows for smooth continuous rotation. Quaternion is defined by four floating point numbers: {x y z w}. @author Mark Powell @author Joshua Slack
