我们提出了一种技术，用于捕获随时间变化的体积数据的参与媒体。激光片反复扫过体积，散射光使用高速相机成像。激光的每次扫描提供了几乎同时的密度值体积。我们演示了在不断变化的视点和照明下渲染的动画，利用测量值的散射相函数和反射。
We present a technique for capturing time-varying volumetric data of participating media. A laser sheet is swept repeatedly through the volume, and the scattered light is imaged using a high-speed camera. Each sweep of the laser provides a near-simultaneous volume of density values. We demonstrate rendered animations under changing viewpoint and illumination, making use of measured values for the scattering phase function and albedo.
