Special SphericalRegion for a point on the sphere.
virtual SphericalCap SphericalPoint::getBoundingCap | ( | ) | const [inline, virtual] |
Return a bounding SphericalCap.
This method is heavily used and therefore needs to be very fast. The returned SphericalCap doesn't have to be the smallest one, but smaller is better.
Reimplemented from SphericalRegion.
virtual OctahedronPolygon SphericalPoint::getOctahedronPolygon | ( | ) | const [virtual] |
Return the octahedron contour representation of the polygon.
It can be used for safe computation of intersection/union in the general case.
Implements SphericalRegion.
virtual QVariantList SphericalPoint::toQVariant | ( | ) | const [virtual] |
Serialize the region into a QVariant map matching the JSON format.
The format is ["POINT", [ra, dec]], with ra dec in degree in ICRS frame.
Implements SphericalRegion.
