Member Enumeration Documentation

enum SFCGAL::algorithm::Buffer3D::BufferType

Buffer type enumeration.

Enumerator
ROUND	Minkowski sum with a sphere.
CYLSPHERE	Union of cylinders and spheres.
FLAT	Construction of a disk on the bisector plane.

Constructor & Destructor Documentation

SFCGAL::algorithm::Buffer3D::Buffer3D	(	const Geometry &	inputGeometry,
		double	radius,
		int	segments
	)

Constructs a Buffer3D object.

Parameters

inputGeometry	The input geometry (must be a Point or LineString)
radius	The buffer radius
segments	The number of segments used to approximate curved surfaces

Exceptions

std::invalid_argument

if the input geometry is not a Point or LineString
