Visual Important-Driven Interactive Rendering of 3D Geometry Model over Lossy WLAN

In this paper, we propose a visual importantdriven interactive rendering method for 3D model over 802.11 WLAN for overcoming the shortcomings of wireless network’s narrow bandwidth, high transmission error rates and mobile devices’ low power supply. This paper first proposes an efficient simplification method based on an improved visual important region detection technique. Then, we develop an efficient hybrid FEC and MAC-Lite model transmission protocol which will transmit the model data by their importance respectively. Finally, we propose a real-time interactive rendering method by an efficient model coding. Experimental results demonstrate that we can obtain better rendering result among lossy environment and gain real-time interactive rendering result.
