Application

Application is the normal ExoJS entrypoint.

Responsibilities

• own the canvas
• own the backend/runtime manager
• own the input manager
• own the scene manager
• drive the frame lifecycle
• present the frame

Default backend behavior

new Application() behaves as backend auto-selection:

• prefer WebGPU when available
• fall back to WebGL2 if WebGPU is unavailable or initialization fails

You can still force a backend explicitly:

new Application({ backend: { type: 'webgpu' } })
new Application({ backend: { type: 'webgl2' } })
new Application({ backend: { type: 'auto' } })

Typical usage

import { Application } from 'exojs'

const app = new Application()
await app.start(scene)

Important properties

• canvas
• loader
• inputManager
• sceneManager
• renderManager
• onResize

Important methods

• start(scene)
• stop()
• resize(width, height)
• destroy()

Application owns frame presentation. Scene code should not call display() itself.
