12 //
13 // Class description:
14 //
15 // A UCons is, in the general case, a Phi segment of a cone, with
16 // half-length fDz, inner and outer radii specified at -fDz and +fDz.
17 // The Phi segment is described by a starting fSPhi angle, and the
18 // +fDPhi delta angle for the shape.
19 // If the delta angle is >=2*UUtils::kPi, the shape is treated as
20 // continuous in Phi
21 //
22 // Member Data:
23 //
24 // fRmin1 inside radius at -fDz
25 // fRmin2 inside radius at +fDz
26 // fRmax1 outside radius at -fDz
27 // fRmax2 outside radius at +fDz
28 // fDz half length in z
29 //
30 // fSPhi starting angle of the segment in radians
31 // fDPhi delta angle of the segment in radians
32 //
33 // fPhiFullCone Boolean variable used for indicate the Phi Section
34 //
35 // Note:
36 // Internally fSPhi & fDPhi are adjusted so that fDPhi<=2PI,
37 // and fDPhi+fSPhi<=2PI. This enables simpler comparisons to be
38 // made with (say) Phi of a point.
