Definition at line 1203 of file TGeoMatrix.cxx.

◆ RotateX()

void TGeoRotation::RotateX ( Double_t angle )

overridevirtual

Rotate about X axis of the master frame with angle expressed in degrees.

Reimplemented from TGeoMatrix.

Definition at line 1098 of file TGeoMatrix.cxx.

◆ RotateY()

void TGeoRotation::RotateY ( Double_t angle )

overridevirtual

Rotate about Y axis of the master frame with angle expressed in degrees.

Reimplemented from TGeoMatrix.

Definition at line 1121 of file TGeoMatrix.cxx.

◆ RotateZ()

void TGeoRotation::RotateZ ( Double_t angle )

overridevirtual

Rotate about Z axis of the master frame with angle expressed in degrees.

Reimplemented from TGeoMatrix.

Definition at line 1144 of file TGeoMatrix.cxx.

◆ SavePrimitive()

void TGeoRotation::SavePrimitive	(	std::ostream &	out,
		Option_t *	option = "" )

overridevirtual

Save a primitive as a C++ statement(s) on output stream "out".

Reimplemented from TObject.

Definition at line 1221 of file TGeoMatrix.cxx.

◆ SetAngles() [1/2]

void TGeoRotation::SetAngles	(	Double_t	phi,
		Double_t	theta,
		Double_t	psi )

Set matrix elements according to Euler angles.

Phi is the rotation angle about Z axis and is done first, theta is the rotation about new X and is done second, psi is the rotation angle about new Z and is done third. All angles are in degrees.

Definition at line 1251 of file TGeoMatrix.cxx.

		Double_t	phi1,
		Double_t	theta2,
		Double_t	phi2,
		Double_t	theta3,
		Double_t	phi3 )

Set matrix elements in the GEANT3 way.
