VOID 3D is a 3D model viewer application based on AR technology. It presents 3D models in the real environment which is totally different from ordinary 3D model viewer application. You just need to find a suitable surface to present 3D models in real environment for 360 degrees observation. You can observe 3D models shared by other users or upload your own 3D models. VOID 3D is a 3D model viewer application using AR SDK engine called VOID AR. This application combines AR technology and 3D models to help 3D model fans to present and observe the 3D models in real environment. The unique feature using in this app is called VOID SLAM from VOID AR SDK. VOID SLAM is designed for high quality AR presentation. It is using monocular camera on regular smart phone or smart glasses to reach the same SLAM effect through Hololens. It lowers the threshold for high quality AR applications.
