English(EN) Occlusion-Point Reuse for Ray-Traced Ambient Occlusion and Shadow

新的渲染技术增强了环境光遮蔽和软阴影

作者 PulseAugur 编辑部 · [1 个来源] · 2026-07-28 04:00

研究人员开发了一个新的实时渲染框架，提高了环境光遮蔽和软阴影的质量。这种“遮挡点重用”方法在首次命中遮挡点的域内重用追踪样本，而不是直接重用最终着色或光线样本。该方法将AO和区域光阴影估计器转换为遮挡域积分，并使用多重重要性采样组合相邻样本。实验表明，与标准的射线追踪方法相比，该技术产生了更高质量的AO和阴影，并且在相似的计算成本下，比光线样本重用方法提高了阴影质量。 AI

影响提高了环境光遮蔽和软阴影的实时渲染质量，可能增强游戏和模拟中的视觉保真度。

用于光线追踪环境光遮蔽和阴影的遮挡点重用

arXiv:2607.23122v1 Announce Type: cross Abstract: Ambient occlusion (AO) and soft shadows are critical visibility cues for spatial perception in real-time rendering. Hardware ray tracing provides a direct way to evaluate these effects, enabling ray-traced AO and area-light shadow…
