threlte

• Purpose: Threlte is a Svelte library designed to simplify the creation of interactive 3D applications for the web. It offers a declarative, type-safe, reactive, and interactive API.

• Target Audience: Developers looking to build 3D web applications using Svelte, with support for physics, animations, and interactivity.

• Key Features:

  • Clean API: Transparently exposes all Three.js objects through a declarative interface.
  • Hooks: Provides low-level access to contexts like animation frames and rendering.
  • Plugins: Allows extending Threlte with custom logic.
  • Events: Svelte-native state transformation handling.
  • Interactivity: Easy reaction to user inputs on 3D objects.

• Core Packages:

  • @threlte/core: Declarative Svelte bindings for Three.js.
  • @threlte/extras: Productivity-boosting enhancements.
  • @threlte/gltf: CLI for converting GLTF assets into reusable components.
  • @threlte/rapier: Physics engine integration via Rapier.
  • @threlte/theatre: Animation studio via Theatre.js.
  • @threlte/xr: VR/AR components and hooks.
  • @threlte/flex: Flexbox-like layout engine integration.
