Struct CurveFitOptions 

pub struct CurveFitOptions {
    pub degree: u16,
    pub control_point_count: usize,
    pub parameterisation: Parameterisation,
    pub interpolate_endpoints: bool,
    pub smoothing: f64,
    pub parameter_correction_iterations: usize,
}

Options for fit_curve3.

Fields

degree: u16

Degree of the fitted curve. Must be at least 1.

control_point_count: usize

Number of control points to solve for. Must be strictly between degree and the number of input points (inclusive of equality, which degenerates to interpolation).

parameterisation: Parameterisation

Parameter assignment.

interpolate_endpoints: bool

Constrain the first and last control points to equal the first and last input points exactly, by equality-constrained least squares rather than as an incidental consequence of the basis.

smoothing: f64

Weight of an optional second-difference smoothing term on the control polygon (a discrete fairness energy). Zero disables it. Must be finite and non-negative.

parameter_correction_iterations: usize

Newton parameter-correction passes (Hoschek and Lasser, section 9.3) run after the initial solve: each pass projects every point onto the current curve and refits with the corrected parameters. Zero skips correction and uses the assigned parameters as-is.
