The Blitz3d game engine uses the .b3d
extension, which is provided by this crate.
```rust let bytes = unimplemented!();
let b3d = b3d::B3D::read(bytes).unwrap();
let vertices = b3d.node.mesh.vertices.vertices; let positions: Vec<_> = vertices.iter().map(|v| v.position).collect(); let normals: Vec<_> = vertices.iter().map(|v| v.normal).collect();
println!("Postions: {:#?}", positions); println!("Normals: {:#?}", normals); ```
