Struct Rectangle3

pub struct Rectangle3 {
    pub origin: Point3,
    pub x: Vec3,
    pub y: Vec3,
}

A planar rectangle in three-dimensional space.

Stored as a corner and two edge vectors rather than four corners, so the parallelogram property holds by construction and cannot drift as corners are edited independently. Whether x and y are perpendicular is not enforced: an importer may produce a sheared quad, and refusing it here would lose data the caller may still want to inspect or repair.

Fields

origin: Point3

Corner the edge vectors start from.

x: Vec3

First edge vector, from origin.

y: Vec3

Second edge vector, from origin.

Implementations

impl Rectangle3

pub const fn new(origin: Point3, x: Vec3, y: Vec3) -> Self

Construct from a corner and two edge vectors.

pub fn corners(&self) -> [Point3; 4]

The four corners, counter-clockwise about normal.

pub fn normal(&self) -> Vec3

Unnormalized normal of the plane the rectangle lies in.

pub fn area(&self) -> Scalar

Area of the rectangle, which is the parallelogram area when sheared.

pub fn center(&self) -> Point3

Centre point.

Trait Implementations

impl Clone for Rectangle3

fn clone(&self) -> Rectangle3

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Rectangle3

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

Formats the value using the given formatter.

impl PartialEq for Rectangle3

fn eq(&self, other: &Rectangle3) -> 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.
