The AngleAxis class provides a representation for orientation in 3D space using an angle in degrees and a rotation axis. This class is similar to a quaternion, except that a normalized quaternion only represents -PI to +PI rotation. Angles can be greater than 360 and so specify multiple revolutions, unlike quaternions. Rotations follow the right-hand-rule.
extracts the rotation component as an angleaxis
AngleAxis can convert to Matrix3's, Quat's, Eulerangle's
Creates a new copy of the angleaxis value. For example:
newAngleAxis = copy oldAngleAxis
The new value contains a copy of the input angleaxis value, and is independent of the input angleaxis value.
Random rotation in degrees, but uses quat Slerp, so loses multiple revolution angles.
