Struct RansacLineModel 

pub struct RansacLineModel {
    pub a: f64,
    pub b: f64,
    pub c: f64,
}

A 2D line in implicit form a x + b y + c = 0 with the normal (a, b) normalized so that a² + b² = 1.

Fields

a: f64

x coefficient of the normal.

b: f64

y coefficient of the normal.

c: f64

Signed offset.

Implementations

impl RansacLineModel

pub fn from_two_points(p1: Point, p2: Point) -> Option<Self>

Builds a line through two points.

Returns None when the points are coincident (within DEGENERATE_EPSILON). The normal (a, b) is perpendicular to the direction p2 - p1.

pub fn distance_to(&self, p: Point) -> f64

Perpendicular distance from a point to the line (a, b normalized).

pub fn direction(&self) -> (f64, f64)

Unit direction vector of the line: (-b, a).

pub fn point_on_line(&self) -> (f64, f64)

The point on the line closest to the origin: (-a*c, -b*c).

Trait Implementations

impl Clone for RansacLineModel

fn clone(&self) -> RansacLineModel

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for RansacLineModel

impl Debug for RansacLineModel

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

Formats the value using the given formatter.

impl PartialEq for RansacLineModel

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