Display 3d model / metadata

March 14, 2016 - 8:39am #1

Hello, i've searched everywhere for a simple direct tutorial on this without success. Basically i wan't to build an app that recognizes an image and shows a 3d model...

 

I've done it with image target with device database but can't seem to find noob information on doing it with cloud recognition. I want a few image targets on the database, each with it's own 3d model to augment. My main difficulties are:

 

  1. What do i put in the metadata? just a .txt with a link pointing to a server with an .obj? what type (and best) of file should i use? .obj, .3ds, .dae, .unity3d
  2. after image/cloud reco i want for example a dragon flying arround, on another i want something completelly different, so i need to, for every target, to have a unity scene that i need uploaded, right? how do i do this?
  3. does unity or vuforia have the ability to cache the downladed scenes on device for faster display next time? does the unity loadFromCacheOrDownload does that?
  4. what is the size recomendation for a model/scene to be downloaded when target recognized?    

For now i guess these are my doubts. Thanks in advance for any help.
