<model-viewer> vs. Verge3D

Q: How does Needle Engine compare to ?

Google's is a web component for embedding a single 3D model with basic rotation and AR placement via HTML attributes. Needle Engine is for building full interactive 3D/XR applications — configurators, multi-user apps, games — with custom logic, a built-in optimization pipeline and Unity/Blender authoring.
