I'm not sure I've understand all aspects of surface finish. Even going through the G4OpBoundaryProcess.cc source file I have some doubts. I know what a polished or ground surface is. What I'm not sure is what a frontpaint and a back paint is.
1.Is a frontpaint a paint directly applied on the solid surface (like a house paint)?
2.Is a backpaint a reflector coating (some thin foil a few mircometers away from the actual volume surface)?
Imagine I want to test two diferent kinds of surface finish:
A)Polished surface with a difuse reflector coating (e.g. carbon foil) a few micrometers apart from the polished surface.
B)Same as A) but with a specular reflector (e.g. aluminium).
I'm changing surface finish interactively, using a CmdWithAnInteger and a method in my DetectorConstruction class named SetSurfaceFinish. This method takes an integer. In the method SetSurfaceFinish I simply assing the integer to a G4OpticalSurfaceFinish enumeration variable which I have in my Detector Construction class, (surfaceFinish = inputInteger). Is this a bad thing do?
Thank you for your attention and any comments that might help me.
