Acceleration by programmable GPU on realizing 3D movie playback

Detailed research is conducted on video texture for 3D movie play application and current research situation, problem and challenge in the world are analyzed in this paper. Then an effective solution is presented. Direct Show is used to manage the video data while Direct 3D serves as graphic rendering API. This paper extracts the parallel computing module from the fixed rendering pipeline and takes full use of programmable GPU to accelerate the rendering process. In plus, GPU texture compression is used to solve the problem of limited graphic memory. The experiment and simulation prove that the designed method can effectively uplift the frame rate, alleviate the CPU burden and solve the bottleneck in real-time rendering. Finally, it is rather practical in certain applications.
