contains2D()

bool luciad::Patch::contains2D

(

Coordinate

point

)

const

Returns if this patch contains the given point.

For these calculations, the height value of the given point or base geometry is ignored. I.e. only the horizontal coordinates are taken into account.

Limitations:

• Currently, this function doesn't support patches with a CompositeRing as base geometry. In that case, an exception is thrown.
• For patches with PolylineRing base geometries, a spherical approximation is used.
• For patches with geodetic PolylineRing base geometries, LineInterpolationType::Linear is not supported.

Parameters

point

a point, defined in the same reference as the reference of this Patch

Returns

whether this patch contains the given point.

Exceptions

luciad::InvalidArgumentException

when calling this function on a patch with a geodetic PolylineRing base geometry with linear interpolation.

getBaseGeometry()

const std::shared_ptr< Ring > & luciad::Patch::getBaseGeometry

(

)

const

Returns the base ring geometry on which the patch is based.

Returns

the base ring geometry on which the patch is based.

getBounds()

Bounds luciad::Patch::getBounds ( ) const

overridevirtual

Returns the bounds for the geometry object.

Returns

the bounds for the geometry object.

Exceptions

luciad::InvalidArgumentException

if the bounds could not be computed. For example, when the geometry is defined by invalid points.

Implements luciad::Geometry.

getHash()

size_t luciad::Patch::getHash ( ) const

overrideprotectedvirtual

Returns the hash value for this geometry.

Returns

the hash value for this geometry.

Implements luciad::Geometry.

getReference()

std::shared_ptr< CoordinateReference > luciad::Patch::getReference ( ) const

overridevirtual

Returns the coordinate reference of the geometry.

Returns

the coordinate reference of the geometry.

Implements luciad::Geometry.
