多光源并行化算法的实现

针对在绘制具有真实感的图形中光照处理模块串行处理速度慢的问题,提出多光源光照算法的并行化,采用负载均衡的并行策略,重新优化计算模型,单独计算环境光、散射光、镜面光及衰减因子后叠加在一起。计算不同的PE(处理单元)个数使用了不同的分配方案来提高处理速度。实验结果表明,将多光源光照算法并行化,可充分利用资源,发挥多核处理器的处理能力,提高了资源利用率。

Study and Implementation of Lighting Parallelization Algorithm

According to slowly serial processing speed in the photorealistic rendering technology, the paper proposes many lights processing. Using parallel strategy of load balancing and optimizing calculation mode,ambient light 、diffuse light and specular light are added when they are calculated separately. Different number of PE (processing unit) with different schemes is to improve the processing speed .The experimental results show that the parallelization of many lights can make a better use of resources and the processing power of multicore processors. The optimizing of the processing from serial computing into parallel computing accelerate the original operation,as well as resource utilization.
