Vuforia does not have APIs for downloading 3D assets from your own database, but you can certainly take a 3D asset you have downloaded and render it on a cloud reco target. This would be done similarly to how the cloud reco sample is done in the core samples, with the main difference being instead of having the 3D asset already loaded locally on the app, you would need to download it from your database at run time. The logic for rendering it would not be different.
