Struct Face3D 

pub struct Face3D {
    pub outer: Vec<Point3D>,
    pub holes: Vec<Vec<Point3D>>,
    pub normal: Point3D,
}

A planar 3D face consisting of one counter-clockwise (CCW) outer loop (viewed from outside along the outward normal) and zero or more clockwise (CW) interior hole loops.

Fields

outer: Vec<Point3D>

holes: Vec<Vec<Point3D>>

normal: Point3D

Implementations

impl Face3D

pub fn from_outer<P: Into<Point3D> + Copy>(outer_pts: &[P]) -> Self

Construct a simple planar face from an outer loop of 3D vertices, computing its outward unit normal via Newell’s method.

pub fn new(outer: Vec<Point3D>, holes: Vec<Vec<Point3D>>) -> Self

Construct a planar face with holes, computing its outward unit normal from the outer loop.

pub fn area(&self) -> f64

Signed area of the face (outer shell area minus hole areas) projected onto its unit normal.
