Explored Augmented reality using project-tango, which locates the 3D objects exactly in a particular position in the real world. While navigating to that object or nearing that object a pathway should be overlaid to that object as shown in the image below enter image description here

This arrow spreads on the floor(using depth) while walking with the device. Project tango has some 3D Models which extends Object3D. I don't think those models will help to do this. Is there any way or library to get it drawn?

  • Can you load an obj or fbx file? It sounds like you are using Java, some of the Tango examples use Java rajawalli render library, it has a decent mesh loading function. – xuguo May 03 '16 at 18:02
  • Now the problem is not drawing path, but getting the relevant ground level depth points to draw path to a place marked in the adf – user1799171 May 06 '16 at 04:17

Old post, but answering for any future visitors (:

There are now examples for ExperimentalFloorFinding which shows you how to get the floor position from the point cloud data. Combined with Jasons suggestion for loading .obj, or with calling Instantiate() on a prefab, you should be able to find the position and draw the object.
