广义相对论射线追踪被提出作为引力物理学的工具。它展示了如何扩展标准三维光线追踪以允许一般相对论可视化。这种可视化技术提供观察者在引力场影响下看到的图像，并允许通过零测地线探测时空。此外，还提出了一种用于可视化引力透镜产生的焦散表面的技术。广义相对论射线追踪的适用性通过两个例子来证明，即刚性旋转尘埃盘的可视化和曲速驱动度量。
General relativistic ray tracing is presented as a tool for gravitational physics. It is shown how standard three-dimensional ray tracing can be extended to allow for general relativistic visualization. This visualization technique provides images as seen by an observer under the influence of a gravitational field and allows to probe space-time by null geodesics. Moreover, a technique is proposed for visualizing the caustic surfaces generated by a gravitational lens. The suitability of general relativistic ray tracing is demonstrated by means of two examples, namely the visualization of the rigidly rotating disk of dust and the warp drive metric.
