Struct SimpleMesh 

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

A simple indexed triangle mesh using [f64;3] vertices.

Fields

vertices: Vec<[f64; 3]>

Vertex positions.

triangles: Vec<[usize; 3]>

Triangle indices (each triple is one triangle).
