threejs indexdb

Three.js is a JavaScript library for creating 3D graphics and animations in the web browser. IndexedDB is a browser-based database that allows you to store and retrieve large amounts of data in the browser.

While Three.js does not have a built-in feature for using IndexedDB, you can still use IndexedDB with Three.js by storing your Three.js objects as JSON data and then saving that data into IndexedDB. You can then retrieve the data from IndexedDB and use it to recreate your Three.js objects.

Here is a basic example of how you can use IndexedDB with Three.js:

1. Create a Three.js scene with some objects.
2. Convert the scene to JSON data using the `THREE.Object3D.toJSON()` method.
3. Save the JSON data into IndexedDB using the `indexedDB` API.
4. Retrieve the JSON data from IndexedDB using the `indexedDB` API.
5. Create new Three.js objects from the retrieved JSON data using the `THREE.Object3D.fromJSON()` method.
6. Add the new objects to your Three.js scene.

Keep in mind that using IndexedDB with Three.js can be complex and may require some knowledge of both technologies. Additionally, IndexedDB is not supported in all browsers, so you may need to provide a fallback option for browsers that do not support it.
