In directory sc8-pr-cvs1.sourceforge.net:/tmp/cvs-serv22231/doc/tex

Modified Files:
	quat.tex 
Log Message:
quat.fromAngleAxis() now accepts an axis that is zero. The axis also doesn't have to be normalized

  \begin{methoddesc}{toAngleAxis}{}
  Returns a tuple containing the angle (in radians) and the axis of rotation.
  \end{methoddesc}
  
  \begin{methoddesc}{fromAngleAxis}{angle, axis}
! Initializes \var{self} from an angle (in radians) and an axis of rotation
! and returns \var{self}. New in version 1.1: The initialized quaternion will
! be a unit quaternion.

--- 82,93 ----
  \begin{methoddesc}{toAngleAxis}{}
  Returns a tuple containing the angle (in radians) and the axis of rotation.
+ The returned axis can also be zero if the rotation is actually the identity.
  \end{methoddesc}
  
  \begin{methoddesc}{fromAngleAxis}{angle, axis}
! Initializes \var{self} from an angle (in radians) and an axis of
! rotation and returns \var{self}. The initialized quaternion will be a
! unit quaternion. Passing the null vector as axis has the same effect
! as passing an angle of 0 (i.e. the quaternion will be set to (1,0,0,0)).
