Detailed Description

Member Function Documentation

virtual SphericalCap SphericalPoint::getBoundingCap ( ) const

inlinevirtual

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

It can be used for safe computation of intersection/union in the general case.

Implements SphericalRegion.

virtual QVariantList SphericalPoint::toQVariant ( ) const

virtual

The format is ["POINT", [ra, dec]], with ra dec in degree in ICRS frame.

Implements SphericalRegion.
