import * as Copper from 'copper3d';
    const allScenes = new Copper.Scenes(HTMLElement, 4, {0, 0, 1000});
    allScenes.animate();

In the HTML file, Vue or React components,
you should create a HTMLElement container for copper3d.
E.g., in index.html

    <div id="container_root"></div>

And the css for container might be:

    #container_root {
            width: 100vw;
            height: 100vh;
        }

In JS:

    import * as Copper from "copper3d";
    const container = document.querySelector("#container_root");
    const numberOfScene = 3;
    const allScenes = new Copper.Scenes(container, numberOfScene);

    const scene1 = allScenes.getScene(0);
    const scene2 = allScenes.getScene(1);
    const scene3 = allScenes.getScene(2);

    Copper.createTestMesh(scene1);
    Copper.createTestMesh(scene2);
    Copper.createTestMesh(scene3);

    allScenes.animate();
