Struct SeriesField2

pub struct SeriesField2 {
    pub u: Basis,
    pub v: Basis,
    pub coefficients: Vec<Vec<f64>>,
}

A field over the parameter plane: sum c[i][j] B_i(u) B_j(v), with the bases of Basis along each parameter. The form a plane’s, quadric’s or torus’s equation takes on an analytic surface.

Fields

u: Basis

The basis along u.

v: Basis

The basis along v.

coefficients: Vec<Vec<f64>>

coefficients[i][j] multiplies term i in u and term j in v.

Implementations

impl SeriesField2

pub fn value(&self, p: DVec2) -> f64

The field’s value at p.

pub fn jet(&self, p: DVec2) -> Jet2

Value, gradient and Hessian at p.

pub fn magnitude(&self) -> f64

The sum of the coefficients’ magnitudes: a bound on the field over the whole Fourier range, and the scale its rounding is measured in.

pub fn is_finite(&self) -> bool

Whether every coefficient is finite.

Trait Implementations

impl Clone for SeriesField2

fn clone(&self) -> SeriesField2

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for SeriesField2

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl PartialEq for SeriesField2

fn eq(&self, other: &SeriesField2) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
