AngleAxis Values

The AngleAxis class provides a representation for orientation in 3D space using an angle in degrees and a rotation axis. T

his class is similar to a quaternion, except that a normalized quaternion only represents -PI to +PI rotation.

AngleAxis angles can be greater than 360 and so specify multiple revolutions, unlike quaternions.

Rotations follow the right-hand-rule.

Constructors

angleaxis <degrees_float> <axis_point3> 
<quat> as angleaxis
<eulerangle> as angleaxis
<matrix3> as angleaxis

extracts the rotation component as an angleaxis

Operators

<angleaxis> == <angleaxis>
<angleaxis> != <angleaxis>
<angleaxis> as <class>

AngleAxis can convert to Matrix3's, Quat's, Eulerangle's

Properties

<angleaxis>.angle: Float
<angleaxis>.axis: Point3
<angleaxis>.numrevs: Integer

Methods

copy<angleaxis>

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 <angleaxis> <angleaxis>

Random rotation in degrees, but uses quat Slerp, so loses multiple revolution angles.
