Title: 使用史瓦西度规的黑洞图像并行光线追踪

Abstract: Rendering images of black holes by utilizing ray tracing techniques is a common methodology employed in many aspects of scientific and astrophysical visualizations. Similarly, general ray tracing techniques are widely used in areas related to computer graphics. In this work we describe the implementation of a parallel open-source program that can ray trace images in the presence of a black hole geometry. We do this by combining a couple of different techniques usually present in parallel scientific computing, such as, mathematical approximations, utilization of scientific libraries, shared-memory and distributed-memory parallelism.

Abstract: 通过利用光线追踪技术来渲染黑洞图像是一种在科学和天体物理可视化多个方面常用的的方法。 同样，一般的光线追踪技术在与计算机图形学相关的领域中也被广泛使用。 在这项工作中，我们描述了一个并行开源程序的实现，该程序可以在存在黑洞几何结构的情况下进行光线追踪以生成图像。 我们通过结合并行科学计算中通常使用的几种技术来实现这一点，例如，数学近似、科学库的使用、共享内存和分布式内存并行性。
