Visual simulation technique using CG has attracted wide attention in many fields. In this paper, we propose a method of modeling and visualizing pearls to implement a pearl visual simulator. Pearls manifest a very specific optical phenomenon. To investigate this feature, we propose a physical model considering the multiple reflection in spherical bodies. In our previous work, interference component, mirroring component and texture are considered as the principal factors for realistic representation of pearl. This paper proposes two additional factors to improve the visualization quality, which corresponds to internal blurring of an incident light and partial coherent interference. We developed a fast algorithm using subsurface reflection distribution to represent a blur. Experimental result shows the physics-based-modeling of internal blurring in subsurface multi-layer structure of a pearl and a partical coherent interference model are effective for high quality visualization.
