inlinevirtual |
Return the area of the region in steradians.
Reimplemented from SphericalRegion.
Definition at line 757 of file StelSphereGeometry.hpp.
|
inlinevirtual |
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.
Definition at line 760 of file StelSphereGeometry.hpp.
|
inlinevirtual |
Return the octahedron contour representation of the polygon.
It can be used for safe computation of intersection/union in the general case.
Implements SphericalRegion.
Definition at line 753 of file StelSphereGeometry.hpp.
|
inlinevirtual |
Return a point located inside the region.
Reimplemented from SphericalRegion.
Definition at line 759 of file StelSphereGeometry.hpp.
|
inlinevirtual |
Return true if the region is empty.
Reimplemented from SphericalRegion.
Definition at line 758 of file StelSphereGeometry.hpp.
|
inlinevirtual |
Serialize the region. This method must allow as fast as possible serialization and work with deserialize().
Implements SphericalRegion.
Definition at line 764 of file StelSphereGeometry.hpp.
|
virtual |
Serialize the region into a QVariant map matching the JSON format.
The format is ["EMPTY"]
Implements SphericalRegion.
