摘要：Daylight simulation problem is a difficult problem in computer graphics due to the complexity of daylight itself. Based on the purposes of simplifying the traditional simulation process and improving the realism at the same time, this paper proposes an image-based daylight simulation method in which color temperature is used to describe daylight. This method can simulates various daylights at different color temperature realistically by using only one general image. The main idea of this approach is using a spectra database, called SOCS, to generate a spectral reflectance image from a general image. The experimental results illustrate the efficiency of this approach.
