面向移动终端的分布并行化渲染

Distributed parallel rendering method for mobile terminals

目的随着移动互联技术和实时渲染技术的快速发展,面向移动终端的3维展示提供了远程交互式的模型渲染,但较高的渲染计算复杂度与较大的数据处理规模,影响了移动终端3维展示的渲染质量和实时性。针对以上不足,提出一种面向移动终端的分布并行化渲染方法。方法该方法将渲染任务分布到服务端与终端,服务端采用层次细节模型控制场景复杂度,生成初次渲染图像;终端采用基于图像的渲染技术再次绘制图像,提高渲染质量,同时在渲染过程中利用CUDA(compute unified device architecture)并行计算加速渲染数据处理。结果本方法有效提高了渲染速度,降低了数据传输量,并保证了图像质量,帧率和数据传输量优化了大约10.8%。结论本文方法为面向移动终端的3维展示提供了很好的解决途径,在移动网络环境中,能够有效降低服务端负载压力,提高资源利用率并改善用户体验。

Objective Following the rapid development of network and real-time rendering technology, 3D demonstration for mobile terminals can now provide remote interactive real-time model rendering. Increased computing complexity and data handling scale affect the quality and real-time performance of 3D demonstration. Hence, a distributed parallel rendering method for mobile terminals is proposed. The method renders a model in both server and client sides. Method The server side utilizes levels of detail technology to control a scene＇s complexity and generates primary rendering frame views. The cli- ent side employs image-based rendering technology to re-render an image and further improve rendering quality, compute unified device architecture （CUDA） parallel computing is employed to accelerate the process of data rendering. Result Ex- periments show that the method improves rendering speed, reduces the size of transmitted data, and further improves image quality, frame rate, and data traffic optimization by approximately 10. 8%. Conclusion Hence, a valuable solution for 3D demonstration for mobile terminals is provided. In mobile networks, the proposed method can reduce server side loading pressure and improve resource utilization and customer experience.
