35 | // The polyconical solid G4BREPSolidPCone is a shape defined by a set of |

36 | // inner and outer conical or cylindrical surface sections and two planes |

37 | // perpendicular to the Z axis. Each conical surface is defined by its |
---|
38 | // radius at two different planes perpendicular to the Z-axis. Inner and |

39 | // outer conical surfaces are defined using common Z planes: |
