Useage

• Load demo

import * as Copper from "copper3d";
import { getCurrentInstance, onMounted } from "vue";
let refs = null;
let appRenderer;
onMounted(() => {
  let { $refs } = (getCurrentInstance() as any).proxy;
  refs = $refs;
  const bg: HTMLDivElement = refs.classfy;
  appRenderer = new Copper.copperRenderer(bg);
  const scene = appRenderer.getCurrentScene();
  scene.createDemoMesh();
  appRenderer.animate();
});

• Add options (curently only control gui)

appRenderer = new Copper.copperRenderer(bg, { guiOpen: true });

• Load multiple scenes with gltf-loader

import * as Copper from "copper3d";
import { getCurrentInstance, onMounted } from "vue";

let refs = null;
let appRenderer;
onMounted(() => {
  let { $refs } = (getCurrentInstance() as any).proxy;
  refs = $refs;
  const bg: HTMLDivElement = refs.classfy;
  appRenderer = new Copper.copperRenderer(bg);
  appRenderer.animate();
  loadModel("/Healthy.glb", "health");
});

function loadModel(url, name) {
  let scene1 = appRenderer.getSceneByName(name);
  if (scene1 == undefined) {
    const scene1 = appRenderer.createScene(name);
    appRenderer.setCurrentScene(scene1);
    scene1.loadViewUrl("/noInfarct_view.json");
    scene1.loadGltf(url);
  } else {
    appRenderer.setCurrentScene(scene1);
  }
}
