Babylon.rs

A WebAssembly wrapper for Babylon.js in Rust.

This project is pre-alpha and the api is in active exploration. Current priorities:

get a basic GLTF up
get a camera
get some sort of interaction

This project uses js_ffi for javascript binding and lazy_static for global static singletons fairly extensively.

Idioms

Scenes hold 3D objects
Materials determine how a 3D object looks
When an 3D object drops it's removed from the scene

HelloWorld

use babylon::prelude::*;
#[macro_use]
extern crate lazy_static;
use std::sync::Mutex;

lazy_static! {
    static ref GAME: Mutex<Game> = Mutex::new(Game::new());
}

struct Game {
    scene: Scene,
    shape: Vec<Sphere>,
}

impl Game {
    fn new() -> Self {
        Game {
            scene: Scene::create_from_basic_engine("#renderCanvas"),
            shape: vec![],
        }
    }
}

#[no_mangle]
pub fn main() {
    babylon::js::log("Starting demo...");
    let mut game = GAME.lock().unwrap();
    for _ in 0..10 {
        let mut sphere = Sphere::new(&game.scene, babylon::js::random());
        sphere.set_position(
            babylon::js::random() - 0.5,
            babylon::js::random() - 0.5,
            babylon::js::random() - 0.5,
        );
        game.shape.push(sphere);
    }
}

Materials

let mut game = GAME.lock().unwrap();
for _ in 0..10 {
    let mut cube = Cube::new(
        &game.scene,
        babylon::js::random(),
        babylon::js::random(),
        babylon::js::random(),
    );
    let mut mat = StandardMaterial::new(&game.scene);
    mat.set_diffuse_color(Color::new(babylon::js::random(),babylon::js::random(),babylon::js::random()));
    mat.set_alpha(babylon::js::random());
    cube.set_material(&mat);
    cube.set_position(
        babylon::js::random() - 0.5,
        babylon::js::random() - 0.5,
        babylon::js::random() - 0.5,
    );
    game.shape.push(cube);
}
