ModelSet Upload API

To create a new ModelSet using the upload API, make a POST request to /v1/vps/object with your authentication token, providing the object name, tracking type (full for 360-degree tracking or side for side-view only), and source details including the file type (glb or gltf), provider (web), and coordinate system (RHS for right-handed or LHS for left-handed).

The API will respond with a pre-signed S3 upload URL, unique object ID, and object code. Use the returned uploadUrl to upload your 3D model file directly to S3 via a PUT request with Content-Type: application/octet-stream. Once uploaded, the system will automatically process the model for Object tracking.
