ZOOM PhysicsVectors Package Release Notes

9/15/03

PhysicsVectors v2.2.1, cvs rtag V02-02-01

Update several of the tests to conform to the changes in CLHEP.

• See CLHEP/Vector release notes for details of changes in Vector made to allow all these tbins to build properly.
Update the Formulas and Definitions documentation.

4/4/03

PhysicsVectors v2.2, cvs rtag V02-02-00

Massive cleanups to make all the tbin tests work.
• Mods of tests to eliminate actions invalidated by the CLHEP/Vector merge.
• See CLHEP/Vector release notes for details of changes in Vector made to allow all these tbins to build properly.

7/24/02

PhysicsVectors v2.1.1, cvs rtag V02-01-01

Version update to reflect fixes in CLHEP/Vector
• Fix acos range problem
  Various Rotation routines need to take acos of a quantity built from the rotation components, which due to roundoff was slightly greater than 1. A safe version of acos was substituted.
• Bring up to date with respect to CLHEP changes for platforms not in use at FNAL.
See CLHEP/Vector release notes for details.

4/23/02

PhysicsVectors v2.1, cvs rtag V02-01-00

Version update to reflect fixes in CLHEP/Vector
• Inline all the Rotation*Vector and Rotation*Rotation operations
  This changes was made to bring the speed of the Vector package back up to that of CLHEP 1.6. For example, Rotation*vector is now 3.5 times faster than it had been in CLHEP 1.7.
• Remove virtuallity of specialized Rotations (e.g., RotationX)
  Necessary to effectively perform the above optimization.
See CLHEP/Vector release notes for details.

11/29/01

PhysicsVectors v2.0.4, cvs rtag V02-00-04

Version update to reflect fixes in CLHEP/Vector
• deltaR() more sensible for vectors near phi = - PI
• New method v1.deltaPhi(v2)
• azimAngle() always in range (-PI,PI]
• polarAngle() now always returns a positive theta.
• Fix bug in isNear() for EulerAngles
• eta(Hep3Vector(0,0,0)) returns 0
• Input operator>>accepts same format as output operator<<
• set(x,y) method for Hep2Vector
  This method is provided for completeness.
See CLHEP/Vector release notes for details.

  • Direct use of non-trivial accessors as L-values, as in

     SpaceVector v; v.phi() = myAngle; 

  • Direct application of Rotations and LorentzTransformations to containers of 3- and 4-vectors

Sep 12, 2000:

The following release was announced September 12, 2000:

PhysicsVectors v1.2.11; cvs rtag V01-02-11

New features in release:
Inserted using statements in tests
Necessary to enables tests in builds where namespace is in effect.
Coming soon:
The PhyiscsVectors capabilities are being merged into the CLHEP Vector classes.
• This will allow code to use (for example) Hep3Vector and also get the features of SpaceVector.
• For compatibility with existing code, the ZOOM PhysicsVectors package will remain, but will have mostly forwarding headers which define and namespace the appropriate original ZOOM names.
• The Hep3Vector and HepLorentzVector classes have already been merged with SpaceVector and LorentzVector, respectively. This code will go into the ZOOM cvs for CLHEP after this release is cut. The merged package will be released after the remaining Rotation and LorrentzTrasformation classes are done, and tests of the ZOOM features have been applied.

New features include the general Rotation class as well as special-case rotations such as RotationX. Also, there are now tutorial examples for the SpaceVector class and some for LorentzVector.
While the package provides a superset of CLHEP's Vectors functionality, it still does not contain the full set of intended features. In particular, LorentzTransformation classes are not yet provided (although direct boosts on 4-vectors are supported).
