Real Time Rendering Iridescent Colors Appearing on Soap Bubbles

摘要

We present a novel technique for real-time rendering of iridescent colors appearing on soap bubbles. Previous techniques are based on multi-stage ray tracing techniques, or depend on user specified manual textures, which are unsuitable for real-time dynamic environment such as games. To render iridescent colors appearing on soap bubbles, we deploy optical phase reflectance based on light polarized perpendicular and parallel to the incident plane. On this framework, we implement intersection of the primary rays using rasterization, and efficiently approximate refraction and reflection for real-time performance. In addition, we simulate sloshing effects between the soap film using GPU based Perlin noise. This makes it possible to render the soap bubbles with visually convincing results in real-time dynamic environment.
