Member Function Documentation

◆ getBoundingCap()

virtual SphericalCap AllSkySphericalRegion::getBoundingCap ( ) const

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.

◆ getOctahedronPolygon()

virtual OctahedronPolygon AllSkySphericalRegion::getOctahedronPolygon ( ) const

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

Implements SphericalRegion.

◆ toQVariant()

virtual QVariantList AllSkySphericalRegion::toQVariant ( ) const

The format is ["ALLSKY"]

Implements SphericalRegion.
