App design

The app is the source for events, global values and other core features. On a per frame basis, we can check values of uniforms and other parameters from app.state, we can expect to pick up the updated values without the need to emit there was a change. You can also use state to write your scene shared state like references to textures or parameters you want to share in your render stages that are called from your scene.

scene structure

To create a scene, export a function that returns your render function. Handling cleanup can be done by having your render function return a function for cleanup.

export default function initialize(ctx, app) {
  // initial setup, module state, events, etc
  return function render(state) {
    // draw calls - this function will be run per frame
    return function cleanup() {
      // release any resources and event handlers from initializer
    }
  }
}
