Outline of Final Research Achievements

In this study, we develop light reflection model and geometric model for CG reconstruction of the tangible cultural properties. The deterioration state of an object in the model is measured as change of spectral reflectance. Then the change is implemented to the degradation model of the target object. The geometric model is developed based on complementing methods of loss of the object shape. Furthermore, we develop a multi-spectral rendering system for reproducing the tangible cultural properties.　Finally, we rendered realistic images of the actual tangible cultural properties such as industrial arts work “Twelve hawks” of Meiji period.
