FBX

Loads binary Autodesk FBX (.fbx) files into a SceneModel via FBXLoader, and writes a SceneModel back out via FBXExporter.

v1 covers binary FBX: mesh geometry (positions, polygon triangulation, normals, UVs), per-Model local transforms, basic diffuse materials, and embedded diffuse textures, wired from the FBX object/connection graph. ASCII FBX, animation, skinning, external-file textures, and NURBS are not yet supported.

Drive FBXLoader directly — fetch the bytes, create a SceneModel, and hand both to the loader:

import {FBXLoader} from "@xeokit/sdk/formats/fbx";

const fileData = await (await fetch("model.fbx")).arrayBuffer();
const sceneModel = scene.createModel({id: "myModel"}).value;
await new FBXLoader().load({fileData, sceneModel});
Copy

Export a SceneModel back to FBX with FBXExporter:

import {FBXExporter} from "@xeokit/sdk/formats/fbx";

const arrayBuffer = await new FBXExporter().write({sceneModel});
