吸収係数を考慮したオパールのボリュームモデル構築とその映像化

抄録

Precious opal is a gemstone consist of multiple regions where the light is scattered or diffracted. We have proposed a method for modeling this structure of opal using volumetric representation, and a rendering method based on the photon mapping algorithm. This time, the absorption has been also considered. As the result, we can successfully reproduce a variety of ground colors of opal.
