Struct ConicPoint

pub struct ConicPoint { /* private fields */ }

One exact intersection point of two conics.

Implementations

impl ConicPoint

pub fn is_tangent(&self) -> bool

Whether the conics are tangent here (intersection multiplicity at least two), decided exactly.

pub fn sign_of_conic(&self, other: &Conic) -> Sign

Exact sign of the conic other at this point: zero on it, and for a circle or ellipse negative inside, positive outside.

pub fn side_of_line(&self, a: Point2, b: Point2) -> Sign

Exact side of the directed line a -> b: positive to the left.

pub fn x(&self) -> RealRoot

The exact x coordinate, as a root of an integer polynomial.

pub fn y(&self) -> RealRoot

The exact y coordinate, as a root of an integer polynomial.

pub fn approx(&self) -> Point2

An approximate point, for output only.

pub fn shear(&self) -> i64

The shear used internally (diagnostics).

Trait Implementations

impl Clone for ConicPoint

fn clone(&self) -> ConicPoint

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ConicPoint

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

Formats the value using the given formatter.

impl PartialEq for ConicPoint

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