We present a novel 3D-image-based client-server streaming approach, as an alternative to current video-based streaming for engineering applications on mobile devices. A render server generates multi-layered panoramic 3D impostors on-the-fly. The impostors are compressed and then transmitted to the client. Since impostors can be reused for several frames of a camera path, the necessary bandwidth can be reduced to a level much below video compression. Furthermore, this approach completely eliminates latencies, which are a major problem of 2D-image-based streaming methods. Also, client rendering speed is decoupled from scene size and complexity and server rendering load can be reduced many times compared to continuous 2D streaming. We demonstrate navigating through a CAD model of a Boeing 777 passenger aircraft with 350 million triangles, on a smartphone, remotely connected via an EDGE network, with zero latency, at 60 frames per second. This makes the approach suitable also for Augmented Reality applications.
