Message: Documentation on CalculateExtent  Not Logged In (login) 
Hello GEANTers.
Does anybody have a good reference or documentation on what information CalculateExtent() returns? I've been going over the code, but I am getting bogged down in the conditionals and switch statements. Also, I don't know how to use G4VoxelLimits, and would appreciate an example or two of how they work. I can read the code, of course, but that doesn't necessarily tell me how to use the objects intelligently. For example, consider a hollow cylinder oriented along the Z axis, with a halflength of 10 cm, an inner radius of 3 cm, and an outer radius of 4 cm. If I call CalculateExtent with kZAxis and no transformation, what are pmin and pmax set to? Are they set to +/10 cm, or are they set to 0 (because the Z axis doesn't actually intercept any of the volume). I assume if I call CalculateExtent with kXAxis or kYAxis, I get pmin = +/4 cm. If I call with kRho, I assume I get 3 cm and 4 cm? What if I call with kRadial3D? I am coding up this situation to find out for myself what values are returned, but I'm looking for a more generalized description than one only applicable to G4Tubs. So for any arbitrary shape built up of the standard shape, polyhedra, subtractions/unions/intersections, and so on, what is CalculateExtent intended to return? Thanks for any and all help.
