Struct TriangleFace 

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

Fields

a: Vector3<S>

b: Vector3<S>

c: Vector3<S>

normal: Vector3<S>

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

vertex_normals: Option<[Vector3<S>; 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<S: Scalar> TriangleFace<S>

pub fn try_new(a: Vector3<S>, b: Vector3<S>, c: Vector3<S>) -> 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<S>; 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<S: Scalar> Debug for TriangleFace<S>

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

Formats the value using the given formatter.
