Struct GeoMesh 

pub struct GeoMesh {
    pub vertices: Vec<[f64; 3]>,
    pub faces: Vec<[usize; 3]>,
}

A simple triangle mesh for geodesic computation.

Fields

vertices: Vec<[f64; 3]>

Vertex positions.

faces: Vec<[usize; 3]>

Triangle face indices (each entry is [v0, v1, v2]).

Implementations

impl GeoMesh

pub fn new(vertices: Vec<[f64; 3]>, faces: Vec<[usize; 3]>) -> Self

Create a new geodesic mesh.

pub fn n_vertices(&self) -> usize

Number of vertices.

pub fn n_faces(&self) -> usize

Number of faces.

pub fn build_adjacency(&self) -> Vec<Vec<(usize, f64)>>

Build an adjacency list: for each vertex, list all neighbouring vertex indices along with the edge length.

pub fn face_area(&self, face_idx: usize) -> f64

Compute the area of a triangular face.

pub fn face_normal_raw(&self, face_idx: usize) -> [f64; 3]

Compute the normal of a triangular face (not normalised).
