Struct ParameterSeparation 

pub struct ParameterSeparation {
    pub scale: [Scalar; 2],
    pub sigma: Scalar,
}

A certified lower bound of a surface’s Jacobian over a parameter box.

With D = diag(scale), |S(x) - S(y)| >= sigma |D (x - y)| for x, y in the box, and |J(x) w| >= sigma |D w| at every point of it. scale is |S_u|, |S_v| at the box’s centre as computed; it depends only on the centre.

Fields

scale: [Scalar; 2]

The scaling |S_u|, |S_v| at the box’s centre.

sigma: Scalar

The separation, positive.
