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
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?
