Vec3d | greatCircleIntersection (const Vec3d &p1, const Vec3d &p2, const Vec3d &nHalfSpace, bool &ok) |
Define all SphericalGeometry primitives as well as the SphericalRegionP type.
Vec3d greatCircleIntersection | ( | const Vec3d & | p1, | |
const Vec3d & | p2, | |||
const Vec3d & | p3, | |||
const Vec3d & | p4, | |||
bool & | ok | |||
) |
Compute the intersection of 2 great circles segments.
ok | is set to false if no intersection was found. |
Vec3d greatCircleIntersection | ( | const Vec3d & | p1, | |
const Vec3d & | p2, | |||
const Vec3d & | nHalfSpace, | |||
bool & | ok | |||
) |
Compute the intersection of a great circles segment with another great circle.
ok | is set to false if no intersection was found. |
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).
