Member Function Documentation

virtual SphericalCap EmptySphericalRegion::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 EmptySphericalRegion::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 QVariantList EmptySphericalRegion::toQVariant (  )  const [virtual]

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

The format is ["EMPTY"]

Implements SphericalRegion.
