RTSDF：用于软阴影绘制的实时的有符号距离场生成
RTSDF: Generating Signed Distance Fields in Real Time for Soft Shadow Rendering
摘要：
用于表面表示的有符号距离场（SDF）通常离线生成，随后加载到游戏等交互式应用程序中。由于它们不是每帧更新，因此它们仅提供刚性曲面表示。虽然有一些方法可以在GPU上快速生成它们，但这些方法的效率在高分辨率下受到限制。本文展示了一种新的技术，结合跳跃洪水和光线追踪，以产生近似的SDF实时软阴影近似，实现突出的阴影半影，同时保持互动的帧速率。
英文摘要：
Signed Distance Fields (SDFs) for surface representation are commonly generated offline and subsequently loaded into interactive applications like games. Since they are not updated every frame, they only provide a rigid surface representation. While there are methods to generate them quickly on GPU, the efficiency of these approaches is limited at high resolutions. This paper showcases a novel technique that combines jump flooding and ray tracing to generate approximate SDFs in real-time for soft shadow approximation, achieving prominent shadow penumbras while maintaining interactive frame rates.
