Lighting marble

ABSTRACT

A method is suggested for modeling subsurface light transport through highly scattering materials such as marble. The technique is a natural extension of previous work describing the use of a lattice-Boltzmann method for calculating light transport in clouds and other participating media. Though the technique does not offer real-time performance, it produces accurate results by correctly modeling a diffusion process, and it is highly parallelizable.
