Type	Name
	PointCloud () = default Default constructor — creates an empty point cloud.
	PointCloud (const std::vector< Vector3D< double > > & points) Construct a point cloud from an existing list of points.
void	addPoint (const Vector3D< double > & p) Append a single point.
void	clear () Remove all points.
bool	empty () const Whether the cloud contains no points.
const std::vector< Vector3D< double > > &	getPoints () const Const access to all points.
void	print (std::ostream & os=std::cout) const Print a human-readable summary to a stream.
void	reserve (std::size_t n) Pre-allocate storage for n points.
void	saveAsObj (std::ostream & filename) const Export the points as a Wavefront OBJ file (vertices only).
std::size_t	size () const Number of points in the cloud.

Detailed Description

Provides basic storage, iteration, and OBJ export capabilities. Commonly used as the output of surface sampling algorithms and as input to surface reconstruction.
