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

```rust use babylon::prelude::*;

[macro_use]

extern crate lazy_static; use std::sync::Mutex;

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

struct Game { scene: Scene, shape: Vec, }

impl Game { fn new() -> Self { Game { scene: Scene::createfrombasic_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

rust 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); }
