In this paper, the authors propose a visual important-driven 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, they develop an efficient hybrid FEC and MAC-Lite model transmission protocol which will transmit the model data by their importance respectively.
