// Class description:
|
|
//
|
|
// A G4Sphere is, in the general case, a section of a spherical shell,
|
|
// between specified phi and theta angles
|
|
//
|
|
// The phi and theta segments are described by a starting angle,
|
|
// and the +ve delta angle for the shape.
|
|
// If the delta angle is >=2*pi, or >=pi the shape is treated as
|
|
// continuous in phi or theta respectively.
|
|
//
|
|
// Theta must lie between 0-pi (incl).
|
|
//
|
|
// Member Data:
|
|
//
|
|
// fRmin inner radius
|
|
// fRmax outer radius
|
|
//
|
|
// fSPhi starting angle of the segment in radians
|
|
// fDPhi delta angle of the segment in radians
|
|
//
|
|
// fSTheta starting angle of the segment in radians
|
|
// fDTheta delta angle of the segment in radians
|
|
//
|
|
//
|
|
// 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.
