Struct bevy_math::primitives::Tetrahedron

pub struct Tetrahedron {
    pub vertices: [Vec3; 4],
}

A tetrahedron primitive.

Fields

vertices: [Vec3; 4]

The vertices of the tetrahedron.

Implementations

impl Tetrahedron

pub fn new(a: Vec3, b: Vec3, c: Vec3, d: Vec3) -> Self

Create a new Tetrahedron from points a, b, c and d.

pub fn signed_volume(&self) -> f32

Get the signed volume of the tetrahedron.

If it’s negative, the normal vector of the face defined by the first three points using the right-hand rule points away from the fourth vertex.

pub fn centroid(&self) -> Vec3

Get the centroid of the tetrahedron.

This function finds the geometric center of the tetrahedron by averaging the vertices: centroid = (a + b + c + d) / 4.

pub fn faces(&self) -> [Triangle3d; 4]

Get the triangles that form the faces of this tetrahedron.

Note that the orientations of the faces are determined by that of the tetrahedron; if the signed volume of this tetrahedron is positive, then the triangles’ normals will point outward, and if the signed volume is negative they will point inward.
