35 // Class description:
36 //
37 // A G4Cons is, in the general case, a Phi segment of a cone, with
38 // half-length fDz, inner and outer radii specified at -fDz and +fDz.
39 // The Phi segment is described by a starting fSPhi angle, and the
40 // +fDPhi delta angle for the shape.
41 // If the delta angle is >=2*pi, the shape is treated as continuous
42 // in Phi
43 //
44 // Member Data:
45 //
46 // fRmin1 inside radius at -fDz
47 // fRmin2 inside radius at +fDz
48 // fRmax1 outside radius at -fDz
49 // fRmax2 outside radius at +fDz
50 // fDz half length in z
51 //
52 // fSPhi starting angle of the segment in radians
53 // fDPhi delta angle of the segment in radians
54 //
55 // fPhiFullCone Boolean variable used for indicate the Phi Section
56 //
57 // Note:
58 // Internally fSPhi & fDPhi are adjusted so that fDPhi<=2PI,
59 // and fDPhi+fSPhi<=2PI. This enables simpler comparisons to be
60 // made with (say) Phi of a point.
