| Abstract: | Three-dimensional (3D) graphic scenes require considerable network bandwidth to be transmitted and computing power to be rendered on users' terminals. Toward high-quality display in real time, we propose a sender-driven mechanism for streaming 3D scenes in a resource-constrained environment. By pre-processing the database,objects in the scene are properly weighted upon their rendering importance, and their resolutions are selected accordingly to reduce the bit rate. Partially ordered delivery is then performed using decoding independencies between the objects. Simulation results show the efficacy of the proposed mechanism. For a test benchmark, for example, the proposed algorithm outperforms the comparing heuristic by 4 dB under a 100-KB bit rate. | ||
