Fast Accurate Soft Shadows with Adaptive Light Source Sampling (original) (raw)

Abstract

Figure 1: Our proposed method is capable of selecting and rendering a significantly reduced amount of shadow maps needed for a physically correct soft shadow solution using an adaptive light source subdivision. Left: Scene rendered from far with 289 fixed samples (10 FPS). Middle Left: The same view point rendered with our method with only 25 samples (67 FPS). Middle Right: The same scene, rendered from a closer view point with 289 fixed samples (10 FPS). Right: Our method reduces the number of needed samples to 105 (18 FPS).
