我们提出了一种光谱渲染技术，与现有方法相比，它具有一系列引人注目的优势。关键思想是沿着路径传播能量，以实现少量、恒定数量的变化波长。第一个是主波长，对每条路径进行随机采样，并且所有方向采样仅基于它。附加波长与主波长的距离相等，以便所有路径波长一起始终均匀地覆盖可见光范围。
We present a spectral rendering technique that offers a compelling set of advantages over existing approaches. The key idea is to propagate energy along paths for a small, constant number of changing wavelengths. The first of these, the hero wavelength, is randomly sampled for each path, and all directional sampling is solely based on it. The additional wavelengths are placed at equal distances from the hero wavelength, so that all path wavelengths together always evenly cover the visible range.
