It must **not** be used as a substitute for writing good git commit messages! ------------------------------------------------------------------------------- ## 2025-09-16 Soon Yung Jun (op-V11-03-03) - G4OpBoundaryProcess: Refactor boundary handling at dielectric-dielectric interfaces by replacing goto with a do-while loop to improve readability. Extract transmission logic into a new inline function DoTransmission() and introduce constexpr helper IsBackpainted() to identify backpainted surfaces. ## 2025-09-03 Soon Yung Jun (op-V11-03-02) - G4OpMieHG.cc: Remove redundant acos/cos calls in angular sampling to improve performance and readability. ## 2025-08-10 Soon Yung Jun (op-V11-03-01) - G4OpBoundaryProcess: Refactor for readability and efficiency - Reuse local variables for trigonometric and exponential function results, as well as other repeated expressions. - Improve code readability by replacing simple if–else clauses with ternary operators and making other minor rearrangements. - Replace h_Planck * c_light with a static function for clarity and reuse. ## 2025-07-30 Soon Yung Jun (op-V11-03-00) - G4OpWLS, G4OpWLS2: improve WLS photon energy sampling: enforce energy below the primary photon's energy ## 2024-07-18 Hans Wenzel (op-V11-02-01) - G4OpWLS2.cc: change SetProcessSubType from fOpWLS to fOpWLS2 ## 2024-05-24 Daren Sawkey (op-V11-02-00) - G4OpBoundaryProcess: Calculate Fresnel reflection/refraction correctly when material property TRANSMITTANCE is specified. The ratio of Fresnel reflection/refraction now does not change when a non-zero transmission is specified. Previously, if transmission of X% was specified, there would be transmission of X% as expected, but the ratio of Fresnel refraction to Fresnel reflection would be set to X%.

Do not overwrite Rayleigh scattering length for the material named 'Water' if it has been specified by the user through a call to AddProperty("RAYLEIGH" 21st April 2004 Peter Gumplinger (op-V06-01-00) Assign class members to defaults in DoIt. 17th March 2004 Peter Gumplinger (op-V06-00-03) Assign all class members in constructor. 24th February 2004 Gabriele Cosmo (op-V06-00-02) Added EOL at end of file in G4OpBoundaryProcess.cc to clear compilation warning in Linux-g++. 19th February 2004 Peter Gumplinger (op-V06-00-01) Add process status: NotAtBoundary, SameMaterial, StepTooSmall, NoRINDEX Allow for a skin-surface between mother and daughter volumes, with the daughter skin taking precedence. 2nd February 2004 Peter Gumplinger (op-V06-00-00) Set theStatus = Undefined at start of DoIt Replace usage of 0 with NULL. 1st December 2003 Peter Gumplinger (op-V05-02-02) G4OpBoundaryProcess.cc: modified to adopt G4SurfaceProperty. Requires tag "materials-V05-02-00". Replaced usage of NULL with 0. 4th October 2003 Gabriele Cosmo (op-V05-02-01) Modified GNUmakefile: added dependency to new module "geometry/navigation". Coworks with "geometry-V05-02-00" and "digits_hits-V05-02-00". 23rd September 2003 Peter Gumplinger (op-V05-02-00) Add WLS (wavelength shifting) process 15th March 2003 Peter Gumplinger (op-V05-00-01) Change logic for assigning of Rindex2; bug report #444 4th February 2003 Peter Gumplinger (op-V05-00-00) Fix calculation of polarization for perpendicular incidence when Rindex1 > Rindex2; bug report #442 12th November 2002 Peter Gumplinger (op-V04-01-01) Fix calculation of polarization on dielectric dielectric interfaces; bug report #427 28th March 2002 Peter Gumplinger (op-V04-00-01) Add public inline method GetStatus and make enum G4OpBoundaryProcessStatus public in G4OpBoundaryProcess.hh 18th October 2001 Peter Gumplinger (op-V03-02-01) Avoid warnings on Linux (gcc-2.95.2) compiler - G4OpRayleigh.cc: remove unused variable 'aMaterial' in PostStepDoIt and 'no_unit' in RayleighAttenuationLengthGenerator - G4OpBoundaryProcess.cc: moved definition of E2_perp, E2_parl, E2_total outside IF-statement 31st August 2001 Peter Gumplinger (op-V03-02-00) - G4OpRayleigh.hh, G4OpBoundary.hh and G4OpAbsorption.hh: changed processName to 'OpRayleigh', 'OpBoundary' and 'OpAbsorption' respectively 30th January 2001 Peter Gumplinger (op-V03-00-05) - G4OpRayleigh.cc: allow for positiv and negative CosTheta and force the new momentum direction to be in the same plane as the new and old polarization vectors still bug report: 207 29th January 2001 Peter Gumplinger (op-V03-00-04) - G4OpRayleigh.cc: fix calculation of SinTheta from CosTheta bug report: 207 23rd January 2001 Peter Gumplinger (op-V03-00-02) - G4OpRayleigh.cc: Allow for Rayleigh scattering length to be defined for arbitrary material through the use of G4MaterialPropertyTable. 5th October 2000 Peter Gumplinger (op-V02-00-02) - G4OpAbsorption.cc: Comment out warning - No Absorption length specified. 3rd August 2000 Gabriele Cosmo (op-V02-00-00r) - G4OpBoundaryProcess.cc: changed RandGauss to G4RandGauss to fix problem of events' reproducibility. - Syncronized with HEAD (only CVS headers changes). 21th October 1999 Peter Gumplinger (op-V00-01-01) - G4OpBoundaryProcess.hh and G4OpBoundaryProcess.cc have been modified (Fill NewMomentum/NewPolarization in DoAbsorption. These members need to be filled since DoIt calls aParticleChange.SetMomentumChange etc. upon return (thanks to: Clark McGrew)
