Ray tracing method for stereo image synthesis using CUDA
摘要：
提出了一种利用并行图形处理器（GPU）实现三维图像可视化的空间三维立体方法。通过在GPU上使用CUDA（Compute Unified Device Architecture）实现光束跟踪法合成三维舞台图像的实验表明，一个计算问题的决策时间约占60%，大部分时间（40%）用于中央处理器和GPU之间的数据传输，用于计算和可视化的组织过程。GPU网络的大小的增加对计算速度的影响的研究表明了并行计算机网络的形成结构和并行化的一般机制的正确任务的重要性。关键词：体三维可视化，立体三维可视化，光线追踪，GPU并行计算，CUDA
英文摘要：
This paper presents a realization of the approach to spatial 3D stereo of visualization of 3D images with use parallel Graphics processing unit (GPU). The experiments of realization of synthesis of images of a 3D stage by a method of trace of beams on GPU with Compute Unified Device Architecture (CUDA) have shown that 60 % of the time is spent for the decision of a computing problem approximately, the major part of time (40 %) is spent for transfer of data between the central processing unit and GPU for computations and the organization process of visualization. The study of the influence of increase in the size of the GPU network at the speed of computations showed importance of the correct task of structure of formation of the parallel computer network and general mechanism of parallelization. Keywords: Volumetric 3D visualization, stereo 3D visualization, ray tracing, parallel computing on GPU, CUDA
