Detailed Description

Represents a uniquely identifyable rotation matrix.

An object of this class is a reference-object and thus leightweighted. It is uniquely identified by its DDName. Further details concerning reference-objects can be found in the documentation of DDLogicalPart.

DDRotation encapsulates CLHEP CLHEP::HepRotation.

Constructor & Destructor Documentation

DDRotation::DDRotation

(

)

refers to the unit-rotation (no rotation at all)

Definition at line 44 of file DDRotation.cc.

DDRotation::DDRotation

(

const DDName &

name

)

Creates a initialized reference-object or a reference to an allready defined rotation.

A reference-object to a defined rotation is created if a rotation was already defined usind DDrot(). Otherwise a (default) initialized reference-object named name is created. At any later stage the rotation matrix can be defined using DDrot(). All initialized-reference object referring to the same name will then immidialtely refere to the matrix created by DDrot().

DDRotation is a lightweighted reference-object. For further details concerning reference-object refere to the documentation of DDLogicalPart.

Friends And Related Function Documentation

DDRotation DDanonymousRot ( DDRotationMatrix *  rot )

friend

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.

Definition at line 194 of file DDRotation.cc.

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

friend

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!

Definition at line 90 of file DDRotation.cc.

DDRotation DDrotReflect ( const DDName &  name, double  thetaX, double  phiX, double  thetaY, double  phiY, double  thetaZ, double  phiZ  )

friend

Defines a rotation-reflection in the Geant3 way.

The resulting matrix MUST be a LEFThanded orthonormal system, otherwise a DDException will be thrown!
