walk in a 3D room (iOS Project)

Hi, I've a 3D room file (.USDZ). Have a look at the 3D file below. iOS supports .USDZ files. [login to view URL] We need to walk (Forward, Backward, Right, Left) in this room by tapping the screen or using the control on phone screen (UP/DOWN/RIGHT/LEFT ...etc). We also need to prevent the walk through the walls. This project has nothing to do with AR. Please do not copy paste your profile .. you'll be ignored if you bid without reading project description. Happy Bidding!
