support loading B3DM format data

[qlanto224]

hello, when I want load B3DM with map, but tips: deck: initialization of ScenegraphLayer({id: 'ceshi-3d-scenegraph-http://localhost:5173/static/20230628/Tile_-3340_9261_0000/Tile_-3340_9261_0000_-0001_0007.b3dm'}): Cannot convert undefined or null to object;

but I use mapbox-gl , it is right.

so , plan to support data like B3DM?

thank you.

maplibre-gl version:3.1.0. this my code:

import maplibregl from "maplibre-gl";
//@ts-ignore
import { Tile3DLayer } from "@deck.gl/geo-layers";
import { Tiles3DLoader } from "@loaders.gl/3d-tiles";
import {Matrix4} from "math.gl"
//@ts-ignore
import { MapboxLayer } from "@deck.gl/mapbox";

const dataUrl = "/static/20230628/tileset.json";
  let layer = new MapboxLayer({
    id: "test-3d",
    type: Tile3DLayer,
    data: dataUrl,
    loader: Tiles3DLoader,
    onTileError: (err) => {
      console.log(err);
    },
    onTilesetLoad: (tileset) => {
      tileset.setProps({ maximumScreenSpaceError: 1 });
      const { cartographicCenter, zoom } = tileset;
      layer.viewState = {
        center: cartographicCenter,
        zoom,
      };

      let mdMtx = new Matrix4().makeTranslation(1, 1, -200);
      tileset.modelMatrix = mdMtx;
      map.jumpTo(layer.viewState);
    },
  });
  map.addLayer(layer);

The current examples we have are with gltf files. I'm not an expert of 3D formats, but if you can convert from b3dm to gltf your might be able to use the existing examples.
