Upon each iteration, new points are added to the list of interpolated points with associated values. These points are:
Points on the mesh which fall far from the implicit surface previously defined (with an associated zero value).
Points on the implicit surface previously defined which fall from the triangle mesh (with an associated value equal to the signed distance of the point from the mesh).
Distance is measured as real distance divided by the radius of regularity to punish errors around regions of high curvature with greater severity.
