DDRotation DDanonymousRot

(

DDRotationMatrix *

rot

)

Defines a anonymous rotation or rotation-reflection matrix.

It can't be addressed by a unique DDName. Once created, it's the users responsibility to keep the reference object DDRotation! Will be mostly used by algorithmic positioning.

DDRotationMatrix* DDcreateRotationMatrix	(	double	thetaX,
		double	phiX,
		double	thetaY,
		double	phiY,
		double	thetaZ,
		double	phiZ
	)

create a new DDRotationMatrix in the GEANT3 style.

The Matrix must be orthonormal - left or right handed - otherwise a DDException is thrown; memory of the returned pointer belongs to the caller

DDRotation DDrot	(	const DDName &	ddname,
		DDRotationMatrix *	rot
	)

Definition of a uniquely identifiable rotation matrix named by DDName name.

DDrot() returns a reference-object DDRotation representing the rotation matrix rot.

The user must not free memory allocated for rot!
