Struct MeshData 

pub struct MeshData {
    pub vertices: Vec<[f64; 3]>,
    pub faces: Vec<[usize; 3]>,
    pub normals: Vec<[f64; 3]>,
    pub uvs: Vec<[f64; 2]>,
    pub material_ids: Vec<usize>,
}

Container for mesh geometry and per-vertex attributes.

Fields

vertices: Vec<[f64; 3]>

Vertex positions as [f64; 3] triples.

faces: Vec<[usize; 3]>

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

normals: Vec<[f64; 3]>

Per-vertex normals (may be empty).

uvs: Vec<[f64; 2]>

Per-vertex UV coordinates (may be empty).

material_ids: Vec<usize>

Per-face material ID (may be empty).
