Enum Field2

pub enum Field2 {
    Series(SeriesField2),
    Patches(PatchField2),
}

A field over a surface’s parameters whose zero set is a section curve: another surface’s equation read in this surface’s parameters.

Variants

Series(SeriesField2)

Powers and harmonics, on an analytic surface.

Patches(PatchField2)

Piecewise Bernstein polynomials, on a B-spline surface.

Implementations

impl Field2

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

A bound on the field’s size over its whole domain, and the scale its rounding is measured in.

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

The sum of the magnitudes of the terms that make up the value at p: the scale the value’s rounding is measured in there. A power series read far from its origin has terms much larger than its coefficients, and a value that cancels them to near zero carries their rounding.

pub fn is_finite(&self) -> bool

Whether every coefficient is finite.

Trait Implementations

impl Clone for Field2

fn clone(&self) -> Field2

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Field2

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

Formats the value using the given formatter.

impl PartialEq for Field2

fn eq(&self, other: &Field2) -> 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.
