Livelink React

About

Livelink React is a React library that sits on top of Livelink.js and provides core React components to easily build 3dverse applications.

Installation

To install the library, run:

npm install @3dverse/livelink-react

Usage

Here's a snippet for the simplest application:

import React from "react";
import { Livelink, Canvas, Viewport, CameraController, useCameraEntity } from "@3dverse/livelink-react";

function App() {
  return (
    <Livelink token="your-authentication-token" sceneId="your-scene-id">
      <AppLayout />
    </Livelink>
  );
}

function AppLayout() {
  const { cameraEntity } = useCameraEntity();

  return (
    <Canvas width="100vw" height="100vh">
      <Viewport cameraEntity={cameraEntity} style={{ width: "100%", height: "100%" }}>
        <CameraController />
      </Viewport>
    </Canvas>
  );
}

Structure of a Livelink React App

Livelink React provides 3 contexts:

• LivelinkContext
  • Handles the connection to the Livelink server and gives access to the resulting session.
• CanvasContext
  • Creates an HTML <canvas> element and its underlying RenderingSurface and provides access to them.
• ViewportContext
  • Creates a Livelink.Viewport and assign a <div> element to it and attach the provided camera.

with their 3 respective components.

• <Livelink>
  • Instantiates a LivelinkContext
• <Canvas>
• <Viewport>

It also provides a component

• <CameraController>

and 2 hooks:

• useEntity()
• useCameraEntity()
