We present real-time stochastic lightcuts, a real-time rendering method for scenes with many dynamic lights. Our method is the GPU extension of stochastic lightcuts [Yuksel 2019], a state-of-art hierarchical light sampling algorithm for offline rendering. To support arbitrary dynamic scenes, we introduce an extremely fast light tree builder. To maximize the performance of light sampling on the GPU, we introduce cut sharing, a way to reuse adaptive sampling information in light trees in neighboring pixels.
