 Dear all,  

 There have been added in VMC new functions for definition of  surfaces and material properties for optical physics:  TVirtualMC:

    virtual void  DefineOpSurface(...);
    virtual void  SetBorderSurface(...);
    virtual void  SetSkinSurface(...);

    virtual void SetMaterialProperty(...);  TVirtualMCApplication:

    virtual void ConstructOpGeometry() {}

 These new functions make possible to set materials and surfaces  properties for optical physics in Geant4; this new setting has no  impact for Geant3. They complete already existing TVirtualMC function  SetCerenkov() which stays as before.

 All settings via these new functions, as well as via  SetCerenkov have to be done in the new VMC application  function ConstructOpGeometry() instead of ConstructGeometry().  In case of Geant3, it does not matter, but in case of Geant4  this is necessary.  

 There is also added a new VMC example (E06),  which redefines via VMC Geant4 novice example N06 demonstrating  optical photon generation and transport.

 Besides that, there is added visualization settings for G3+TGeo  (examples E02, E03) and demonstration on including own user Geant4  physics list (E03).  

 All is available in the development versions (CVS head)  of Root, geant3 and geant4_vmc.  

 Best regards,  

 Ivana
