Remote non-photorealistic rendering of 3D models on mobile devices

Nowadays, the pervasiveness of mobile devices has increased steadily in our daily life. We utilize them for the chief purposes of communication, learning and entertainment. And there is a growing interest in providing more applications for these small devices. In the realms like digital entertainment, product concept design and architecture draft, we strongly desire to mobile access to the 3D models conveniently although the limited resources like network bandwidth, graphical resources and computing power in such small devices. To overcome the disadvantages of the devices and balance the workload and performance between the client and server, in this paper we present a real time remote rendering method by transferring only the line primitives to client devices from server side, which will be rendered in the client side locally with various non-photorealistic rendering (NPR) techniques. We propose a general framework that enables the user to interactively go through the 3D models with his personal mobile device anytime and anywhere. Moreover, we can enrich the users' experience since NPR based images are usually eyes-attracting.
