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

在间接光照环境下，逼真地渲染其光学特性依赖于光的波长的物体是很重要的。为了实现这一研究目标，我们开发了一种基于光子映射的光谱绘制方法，这是计算机图形学中的一种典型的全局光照模型算法。此外，我们改进了一种利用色调映射技术来逼真显示高动态范围光谱图像的方法，该方法考虑了人眼的视觉特性。

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.
