Detailed Description

Special SphericalRegion for the whole sphere.


Member Function Documentation

virtual OctahedronPolygon AllSkySphericalRegion::getOctahedronPolygon (  )  const [inline, 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 double AllSkySphericalRegion::getArea (  )  const [inline, virtual]

Return the area of the region in steradians.

Reimplemented from SphericalRegion.

virtual bool AllSkySphericalRegion::isEmpty (  )  const [inline, virtual]

Return true if the region is empty.

Reimplemented from SphericalRegion.

virtual Vec3d AllSkySphericalRegion::getPointInside (  )  const [inline, virtual]

Return a point located inside the region.

Reimplemented from SphericalRegion.

virtual SphericalCap AllSkySphericalRegion::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 QVariantMap AllSkySphericalRegion::toQVariant (  )  const [virtual]

Serialize the region into a QVariant map matching the JSON format.

The format is {"type": "ALLSKY"}

Implements SphericalRegion.

virtual void AllSkySphericalRegion::serialize ( QDataStream &  out  )  const [inline, virtual]

Serialize the region. This method must allow as fast as possible serialization and work with deserialize().

Implements SphericalRegion.
