Struct R3 

pub struct R3 {
    pub x: Rational,
    pub y: Rational,
    pub z: Rational,
}

Exact 3D point (or vector). Derived Ord is lexicographic (x, y, z) for exact vertex welding in output assembly.

Fields

x: Rational

y: Rational

z: Rational

Implementations

impl R3

pub fn new(x: Rational, y: Rational, z: Rational) -> Self

pub fn from_vec3(v: Vec3) -> Self

pub fn to_vec3_rounded(&self) -> Vec3

pub fn sub(&self, o: &R3) -> R3

pub fn add(&self, o: &R3) -> R3

pub fn scale(&self, s: &Rational) -> R3

pub fn dot(&self, o: &R3) -> Rational

pub fn cross(&self, o: &R3) -> R3

pub fn is_zero(&self) -> bool

pub fn project_drop(&self, axis: usize) -> R2

Drop the coordinate at axis (0=x, 1=y, 2=z), keeping the other two in cyclic order — the paper’s bijective dominant-axis projection used to embed per-triangle 2D arrangements.

Trait Implementations

impl Clone for R3

fn clone(&self) -> R3

Returns a duplicate of the value.

impl Eq for R3

impl Hash for R3

fn hash<__H: Hasher>(&self, state: &mut __H)

impl Ord for R3

fn cmp(&self, other: &R3) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

Equality operator ==.

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

Inequality operator !=.

impl PartialOrd for R3

fn partial_cmp(&self, other: &R3) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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