Struct TriangleFace 

pub struct TriangleFace {
    pub a: Vector3,
    pub b: Vector3,
    pub c: Vector3,
    pub normal: Vector3,
    pub vertex_normals: Option<[Vector3; 3]>,
}

Fields

a: Vector3

b: Vector3

c: Vector3

normal: Vector3

The triangle’s own (flat) normal, from its winding.

vertex_normals: Option<[Vector3; 3]>

The normal of the surface this triangle approximates, at each of its three corners — what a renderer needs to shade a curved face smoothly instead of as a field of facets. None where no surface normal was available (a debug triangle, or a degenerate point like a sphere’s pole), leaving a renderer with the flat Self::normal.

Implementations

impl TriangleFace

pub fn try_new(a: Vector3, b: Vector3, c: Vector3) -> GeopResult<Self>

Computes the normal from the cross product of (b-a) × (c-a). Fails if the cross product is zero (collinear or coincident points).

pub fn with_vertex_normals(self, normals: [Vector3; 3]) -> Self

This triangle carrying the surface normals at its corners, each oriented to agree with the triangle’s own winding — a renderer picks front or back from the winding, so a vertex normal pointing the other way would light the face inside out.

Trait Implementations

impl Clone for TriangleFace

fn clone(&self) -> TriangleFace
