p1 | Start of the great circle segment. |
p2 | End of the great circle segment. |
nHalfSpace | Normal of the plane separating half space to intersect with. |
ok | is set to false if no intersection was found. |
QDataStream& operator<< | ( | QDataStream & | out, |
const SphericalRegionP & | region | ||
) |
Serialize the passed SphericalRegionP into a binary blob.

SphericalRegionP & | region | ||
) |
Load the SphericalRegionP from a binary blob.
Return whether the halfspace defined by the vectors v1^v2 and with aperture 90 deg contains the point p.
The comparison is made with a double number slightly smaller than zero to avoid floating point precision errors problems (one test fails if it is set to zero).
