3114th Jun 2010 Peter Gumplinger (op-V09-03-03)
32              ProposeLocalEnergyDeposit(thePhotonMomentum) every time the
33              photon is fStopAndKill because of NoRINDEX. This will trigger
34              scoring when a photon encounters a volume not defined as an
35              optical medium (indirect user request):

40              http://hypernews.slac.stanford.edu/HyperNews/geant4/get/opticalphotons/334/1/1.html
41              theFacetNormal was not sampled for polishedbackpainted
42              in DielectricDielectric method of G4OpBoundaryProcess
43
4419th Apr 2010 Peter Gumplinger (op-V09-03-01)
45              fix Problem report #1114 in that for backpainted
46              surfaces theReflectivity is not applied twice.
47              While doing the fix I also completely refashioning the
48              code in the case of type == dielectric_dielect.
49
5019th Jan 2010 Peter Gumplinger (op-V09-03-00)
51              assign PropertyPointers to NULL at the start of the
52              PostStepDoIt, addresses bug report #1094
53
5419th Nov 2009 Peter Gumplinger (op-V09-02-06)
55              change the code such that the LUT are now read in and kept
56              by G4OpticalSurface and not G4OpBoundaryProcess, reordering
57              of enumeration and set theStatus in DielectricLUT.
58
5911th Nov 2009 Peter Gumplinger (op-V09-02-05)
60              add capability of simulating surface reflections
61              with Look-Up-Tables (LUT) containing measured
62              optical reflectance for a variety of surface
63              treatments - Thanks to Martin Janecek and
64              William Moses (Lawrence Berkeley National Lab.)
65
669th  Nov 2009 Peter Gumplinger (op-V09-02-04)
67              G4OpBoundary: initialze theReflectivity and theEfficiency
68              at the beginning of the PostStepDoIt; add method
69              BoundaryProcessVerbose which will now print the process
70              status for every call to PostStepDoIt.
71
725th  Nov 2009 Peter Gumplinger (op-V09-02-03)
73              G4OpBoundary::PostStepDoIt - all dielectric_dielectric
74              surfaces may now have a reflectivity <1; not only
75              'frontpainted' as was the case in the past.
76
776th  May 2009 Peter Gumplinger (op-V09-02-02)
78              G4OpBoundary::PostStepDoIt now throws an G4Exception
79              EventMustBeAborted when an invalid surface normal is returnd;
80              addresses bug report #1060
81
8223th Mar 2009 Peter Gumplinger (op-V09-02-01)
83              for complex index of refraction: (1)resample the reflectivity
84              every time in the do-while of DielectricMetal, but don't
85              re-calculate theFacetNormal (which has already been chosen
86              in CalculateReflectivity), also (2) avoid an infinite loop by
87              resetting iTE and iTM inside the do-while of GetReflectivity;
88              both are bug-fixes.
89
9014th Jan 2009 Peter Gumplinger (op-V09-02-00)

106
10715th Aug 2008 Peter Gumplinger (op-V09-01-05)
