| 40 | CLHEP started in 1992 as a library for fundamental classes
|
|---|
| 41 | mostly needed for, and in fact derived from, the MC event generator
|
|---|
| 42 | MC++ written in C++. Since then various authors added classes to
|
|---|
| 43 | this package, including several contributions made by developers in
|
|---|
| 44 | the Geant4 Collaboration.

| 53 | The Geant4 project contributed to the development of CLHEP. The

| 54 | random number package, physics units and constants, and some of the
|

| 55 | numeric and geometry classes had their origins in Geant4.

| 59 | Geant4 also benefits from the development of CLHEP. In addition
|
|---|
| 60 | to the already mentioned classes for random numbers and numerics,
|
|---|
| 61 | we use the classes for points, vectors, and planes and their
|
|---|
| 62 | transformations in 3D space, and lorentz vectors and their
|
|---|
| 63 | transformations. Although these classes have Geant4 names like
|
|---|
| 64 | G4ThreeVector, these are just typedefs to the CLHEP classes.
