 The choice depends on the shape of the simplex, where the algorithm tries to create regular simplices.
 Alternatively, a good strategy is choosing points somewhere on the edge of a triangle such that the simplex aligns with the gradient of the function; creating an anisotropic triangulation[@dyn1990data].
 This is a similar approach to the anisotropic meshing techniques mentioned in the literature review.
