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: Point2) -> Scalar

The field’s value at p.

pub fn jet(&self, p: Point2) -> Jet2

Value, gradient and Hessian at p.

pub fn magnitude(&self) -> Scalar

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: Point2) -> Scalar

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.
