Development of a Spectral Rendering Method Based on a Global Illumination Model

在间接照明环境下，由于物体的光学特性依赖于光的波长，因此如何逼真地绘制物体是非常重要的。 为了实现这一研究目标，我们提出了一种基于光子映射的光谱绘制方法，光子映射是计算机图形学中全局光照模型的一种典型算法。 此外，我们已经改进了一种方法，用于显示高动态范围的光谱图像逼真地通过使用色调映射技术，考虑到人类的视觉特性。

It is important to render the objects realistically whose optical properties depend on the wavelength of light, under indirect lighting environment. To achieve the research goal, we have developed a spectral rendering method based on a photon mapping method, that is a typical algorithm of a global illumination model in computer graphics. Furthermore, we have improved a method for displaying high dynamic range spectral images realistically by using a tone mapping technique taking into account human visual properties.
