英文摘要： With the mature of the mobile network infrastructure, the widely used fresh mobile handheld devices are becoming a new information exchanging and mobile computing platform. However, the shortcomings of high packet-loss-ratio and error-ratio among wireless network and the limitations of low power consumption and low computing performance for mobile devices, which cannot meet the need of the robust transmission and realtime interaction for 3D model, hinder the further developing of 3D graphics application on mobile devices, such as the applications of e-bussiness, mobile game and kinds of digital media. Therefore, this project mainly discusses model transmission mechanism among wireless network and high performance graphics pipeline on mobile devices. In detail, the project hopes major achievements would be appeared in the following parts. The first part are the researches for error-resilient model transmission and protocol design. The second part are the researches for perceptual optimized model coding and reconstruction. The last part are the researches for speedup technologies and optimized algorithms for mobile 3D graphics pipeline. Through above investigations, this project would provide novel methods and basic principles for the relaziation of efficient 3D model transmission and rendering among wireless network and thus improve or develop both theory and methodology for the research field of moblie graphics computing.
