		KernelFunction	chi_r,
		Scalar	t = `2.5`,
		Metric	aMetric = `Metric()`,
		bool	verbose = `false`
	)

Constructor. Computes the VCM of the given surface.

Parameters

_surface	the digital surface that is aliased in this. The user can secure the aliasing by passing a CountedConstPtrOrConstPtr.
_surfelEmbedding	the chosen embedding for surfels.
_R	the offset radius for the set of points. Voronoi cells are intersected with this offset. The unit corresponds to a step in the digital space.
_r	(an upper bound of) the radius of the support of the kernel function chi_r (note \(\chi_r\) in the VCM paper). The unit corresponds to a step in the digital space. This parameter is used for preparing the data structure that answers to proximity queries.
chi_r	the kernel function whose support has radius less or equal to r.
t	the radius for the trivial normal estimator, which is used for finding the correct orientation inside/outside for the VCM.
aMetric	an instance of the metric (used for the Voronoi map construction).
verbose	if 'true' displays information on ongoing computation.
