35 // Class description:
36 //
37 // A G4Sphere is, in the general case, a section of a spherical shell,
38 // between specified phi and theta angles
39 //
40 // The phi and theta segments are described by a starting angle,
41 // and the +ve delta angle for the shape.
42 // If the delta angle is >=2*pi, or >=pi the shape is treated as
43 // continuous in phi or theta respectively.
44 //
45 // Theta must lie between 0-pi (incl).
46 //
47 // Member Data:
48 //
49 // fRmin inner radius
50 // fRmax outer radius
51 //
52 // fSPhi starting angle of the segment in radians
53 // fDPhi delta angle of the segment in radians
54 //
55 // fSTheta starting angle of the segment in radians
56 // fDTheta delta angle of the segment in radians
57 //
58 //
59 // Note:
60 // Internally fSPhi & fDPhi are adjusted so that fDPhi<=2PI,
61 // and fDPhi+fSPhi<=2PI. This enables simpler comparisons to be
62 // made with (say) Phi of a point.
63 
64 // History:
65 // 28.3.94 P.Kent: old C++ code converted to tolerant geometry
66 // 17.9.96 V.Grichine: final modifications to commit
