three-application v0.2.0

three-application

A general purpose three.js application that manages a renderer initialization, an update loop, window resizing, and mouse movement.

Example

const app = new Application();

app.camera.position.set(0, 0, -5);
app.camera.lookAt(0, 0, 0);

const mesh = new ExampleMesh();
app.scene.add(mesh);

app.addEventListener('update', event => {
  
  // app.time is seconds since app was last started
  mesh.rotation.set(Math.sin(app.time), Math.cos(app.time), 0);

});

app.addEventListener('mousemove', event => {
  
  const scale = app.mouse.x + 1; // app.mouse is normalized to [-1, +1] 
  mesh.scale.set(scale, scale, scale);
  
});

app.start(); // start a render loop with requestAnimationFrame
