◆ operator()() [1/2]

template<typename Grid , typename InterpolationScheme = Trilinear_interpolation<Grid>>

FT & CGAL::Isosurfacing::Interpolated_discrete_values_3< Grid, InterpolationScheme >::operator()	(	const std::size_t	i,
		const std::size_t	j,
		const std::size_t	k
	)

returns the scalar value stored at the grid vertex described by its three indices.

Note: This function can be used to set the value at a grid vertex.

Parameters

i	the index in the `x` direction
j	the index in the `y` direction
k	the index in the `z` direction

Precondition: i < xdim() and j < ydim() and k < zdim()
