Application template

Moving to the branch applicationTemplate inside the src/html/template.html file there is an initial template by which you can start to write your applications. The main part is reported below.

2. Start a session
3. Initialize the scene
4. Create and define the elements properties you want within the scene

        import * as CollaborativeXR from "../../collaborativeXR.min.js"

        const apiKey =  'yourApiKey';
        const appId = 'yourAppId';

        const scene = new CollaborativeXR.Scene(sessionManager);
        scene.initializeScene();
        
        //here the code of your application
        
        scene.activateRenderLoop();

Example

Moving on the example branch, you will have the opportunity to see some application examples made through the framework.

Simple Animation

Inside the file src/html/example_animation.html, you can find out how to create simple holograms and associate them with an animation that is started and stopped via a menu.

Hologram Manipulation

Inside the file src/html/example_robot.html you can find out how to import holograms defined by a file in .gltf format, and how to associate to them a manipulator menu that allows you to move and scale them.

Simple Application

Inside the file src/html/example_animal.html you can find out how to make a simple application consisting of both imported holograms and simple holograms, allow their manipulation, and create GUI for user interaction.
