Struct Triangle 

pub struct Triangle {
    pub id: u32,
    pub a: Point3,
    pub b: Point3,
    pub c: Point3,
    pub bounds: Bounds3,
    pub normal: Point3,
    pub face: u32,
}

One triangle with its cached bounds, unit normal and source face.

Fields

id: u32

Position in the snapshot’s triangles.

a: Point3

b: Point3

c: Point3

bounds: Bounds3

normal: Point3

Unit normal (b - a) × (c - a), normalized. Degenerate triangles never enter a snapshot.

face: u32

Index into MeshSnapshot::faces.

Implementations

impl Triangle

pub fn vertices(&self) -> [Point3; 3]

pub fn area_vector(&self) -> Point3

Twice the signed area vector; its length is twice the area.

pub fn area(&self) -> f64

pub fn centroid(&self) -> Point3

pub fn is_vertical(&self, tol: &Tolerance) -> bool

The triangle’s plane is vertical (normal perpendicular to Z) within the tolerance.

pub fn is_horizontal(&self, tol: &Tolerance) -> bool

The triangle’s plane is horizontal within the tolerance.

pub fn min_z(&self) -> f64

pub fn max_z(&self) -> f64
