Member Function Documentation

◆ contains()

bool SphericalRegion::contains

Returns whether a SphericalRegion is contained into this region.

A default potentially very slow implementation is provided for each case.

◆ getBoundingCap()

SphericalCap EmptySphericalRegion::getBoundingCap ( ) const

inlineoverridevirtual

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.

◆ getOctahedronPolygon()

OctahedronPolygon EmptySphericalRegion::getOctahedronPolygon ( ) const

inlineoverridevirtual

Return the octahedron contour representation of the polygon.

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

Implements SphericalRegion.

◆ getSubtraction()

SphericalRegionP SphericalRegion::getSubtraction

Return a new SphericalRegion consisting of the subtraction of the given region from this.

A default potentially very slow implementation is provided for each case.

◆ intersects()

bool SphericalRegion::intersects

Returns whether a SphericalRegion intersects with this region.

A default potentially very slow implementation is provided for each case.

◆ toQVariant()

QVariantList EmptySphericalRegion::toQVariant ( ) const

overridevirtual

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

The format is ["EMPTY"]

Implements SphericalRegion.
