With the widespread of 3G/4G WAN and the intelligent mobile device, 3D mobile graphics applications have been gotten a rapid development recently. In order to overcome the the limitations of low power consumption and low computing performance for mobile device and the shortcomings of short bandwidth and high latency for the wireless network, this project mainly discusses the method of low cost and low latency hybrid remote rendering for interactive mobile graphics based on our existed researches of the mobile graphics encoding and transmission protocol. In detail, major achievements this project hopes to obtain are the following: 3D model interactive rendering method based on the adaptive spectral graph geometry image; Low latencey remote rendeirng and compression algorithm based on multi-depth images; Low cost hybrid rendering methods for complicated 3D scene on mobile device. Through above investigations, we hope we can solve the following key technologies including adaptive multiresoluation spectral graph geometry image construction, dynamical interactive rendering, multi-depth images compression, quick reference view choosen, visual salient object detection, joint source and channel bit allication for scene image and energy-saving color set optimization model. It can be seen that this project would provide novel methods and basic principles for 3D model low latency and low cost hybrid interactive rendering on the mobile device and thus improve or develop both theory and methodology for the research field of mobile graphics computing.
