Property Value

Setting the angle influences all components of the quaternion. The result is a unit quaternion that specifies a rotation of angle radians around the axis given by Axis.

This property assumes that the quaternion is a unit quaternion. It returns NaN if the w component is numerically greater than 1.0 or less than -1.0.
