//
|
|
// The polyconical solid G4BREPSolidPCone is a shape defined by a set of
|
|
// inner and outer conical or cylindrical surface sections and two planes
|
|
// perpendicular to the Z axis. Each conical surface is defined by its
|
|
// radius at two different planes perpendicular to the Z-axis. Inner and
|
|
// outer conical surfaces are defined using common Z planes:
