The warping function $\omega(x, \ y)$ is needed to compute torsion. Although we can let the user define the place of the source points, a method to decide the best points is desirable.
Description
The approximative solution $\overline{\omega}$ should be as near as possible of the exact (and unknown) solution $\omega$.
At first sight, there are three ways to mesure how good a solution $\overline{\omega}$ is

At first sight, there are three ways to mesure how good a solution $\overline{\omega}$ is
$$J = I{xx} + I{yy} - \int{t{min}}^{t_{max}} \omega \cdot \langle \mathbf{p}, \ \mathbf{p}'\rangle \ dt$$
$$I{\omega \omega} = \int{\Omega} \omega^2 \ dx \ dy$$
$$I = \int{t{min}}^{t_{max}} \omega^2 \ \langle \mathbf{p}, \ \mathbf{p}'\rangle dt$$
