|
|
//
|
|
// A G4Cons is, in the general case, a Phi segment of a cone, with
|
|
// half-length fDz, inner and outer radii specified at -fDz and +fDz.
|
|
// The Phi segment is described by a starting fSPhi angle, and the
|
|
// +fDPhi delta angle for the shape.
|
|
// If the delta angle is >=2*pi, the shape is treated as continuous
|
|
// in Phi
|
|
//
|
|
// Member Data:
|
|
//
|
|
// fRmin1 inside radius at -fDz
|
|
// fRmin2 inside radius at +fDz
|
|
// fRmax1 outside radius at -fDz
|
|
// fRmax2 outside radius at +fDz
|
|
// fDz half length in z
|
|
//
|
|
// fSPhi starting angle of the segment in radians
|
|
// fDPhi delta angle of the segment in radians
|
|
//
|
|
// fPhiFullCone Boolean variable used for indicate the Phi Section
|
|
//
|
|
// Note:
|
|
// Internally fSPhi & fDPhi are adjusted so that fDPhi<=2PI,
|
|
// and fDPhi+fSPhi<=2PI. This enables simpler comparisons to be
|
|
// made with (say) Phi of a point.
