Currently, there are 4 different objects in the public folder for testing. Add your 3D objects to the public folder, use `.gltf` files. We suggest an [OBJ coverter](https://github.com/CesiumGS/obj2gltf), then optimize
your glTF assets with `gltf-pipeline`, [more info](https://www.npmjs.com/package/gltf-pipeline).
