`#include <StelSphereGeometry.hpp>`

## Public Member Functions | |

SphericalPoint (const Vec3d &an) | |

virtual SphericalRegionType | getType () const |

virtual OctahedronPolygon | getOctahedronPolygon () const |

Return the octahedron contour representation of the polygon. | |

virtual double | getArea () const |

Return the area of the region in steradians. | |

virtual bool | isEmpty () const |

Return true if the region is empty. | |

virtual Vec3d | getPointInside () const |

Return a point located inside the region. | |

virtual SphericalCap | getBoundingCap () const |

Return a bounding SphericalCap. | |

virtual QVariantList | toQVariant () const |

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

virtual void | serialize (QDataStream &out) const |

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

virtual bool | contains (const SphericalPolygon &) const |

virtual bool | contains (const SphericalConvexPolygon &) const |

virtual bool | contains (const SphericalCap &) const |

virtual bool | contains (const SphericalPoint &r) const |

virtual bool | contains (const AllSkySphericalRegion &) const |

virtual bool | intersects (const SphericalPolygon &) const |

virtual bool | intersects (const SphericalConvexPolygon &) const |

virtual bool | intersects (const SphericalCap &r) const |

virtual bool | intersects (const SphericalPoint &r) const |

## Static Public Member Functions | |

static SphericalRegionP | deserialize (QDataStream &in) |

Deserialize the region. This method must allow as fast as possible deserialization. | |

## Public Attributes | |

Vec3d | n |

The unit vector of the point direction. |

Special SphericalRegion for a point on the sphere.

static SphericalRegionP SphericalPoint::deserialize | ( | QDataStream & | in |
) | ` [static]` |

Deserialize the region. This method must allow as fast as possible deserialization.

virtual double SphericalPoint::getArea | ( | ) | const` [inline, virtual]` |

Return the area of the region in steradians.

Reimplemented from SphericalRegion.

virtual SphericalCap SphericalPoint::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 SphericalPoint::getOctahedronPolygon | ( | ) | const` [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 Vec3d SphericalPoint::getPointInside | ( | ) | const` [inline, virtual]` |

Return a point located inside the region.

Reimplemented from SphericalRegion.

virtual bool SphericalPoint::isEmpty | ( | ) | const` [inline, virtual]` |

Return true if the region is empty.

Reimplemented from SphericalRegion.

virtual void SphericalPoint::serialize | ( | QDataStream & | out |
) | const` [inline, virtual]` |

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

Implements SphericalRegion.

virtual QVariantList SphericalPoint::toQVariant | ( | ) | const` [virtual]` |

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

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

Implements SphericalRegion.

The unit vector of the point direction.
