Abstract:
In this paper we show how Metropolis Light Transport can be extended
both in the underlying theoretical framework and the algorithmic implementation
to incorporate volumetric scattering. We present a generalization of the
path integral formulation that handles anisotropic scattering in non-homogeneous
media. Based on this framework we introduce a new mutation strategy that
is specifically designed for participating media. Our algorithm includes effects
such as volume caustics and multiple volume scattering, is not restricted to certain
classes of geometry and scattering models and has minimal memory requirements.
Furthermore, it is unbiased and robust, in the sense that it produces satisfactory
results for a wide range of input scenes and lighting situations within
acceptable time bounds.
