heightmap_interpolation.rbf.tension_spline_rbf module

heightmap_interpolation.rbf.tension_spline_rbf.tension_spline_rbf(r, e)

Spline with tension.

Definition of the spline with tension from [2]. You can also find a brief description of its behaviour in [1]. Note that [1] suggests using a polynomial of degree 0 with this RBF.

Parameters

• r – value to evaluate.

• e – tension parameter.

Returns

value of the RBF at r.
