This paper introduces a simple model for subsurface light transport in translucent materials.
The model enables efficient simulation of effects that BRDF models cannot capture, such as
color bleeding within materials and diffusion of light across shadow boundaries. The …

This paper introduces an efficient two-pass rendering technique for translucent materials.
We decouple the computation of irradianceat the surface from the evaluation of scattering
inside the material. This is done by splitting the evaluation into two passes, where the first …

The reflection of light from most materials consists of two major terms: the specular and the
diffuse. Specular reflection may be modeled from first principles by considering a rough
surface consisting of perfect reflectors, or micro-facets. Diffuse reflection is generally …

This paper introduces a shading model for light diffusion in multi-layered translucent
materials. Previous work on diffusion in translucent materials has assumed smooth semi-
infinite homogeneous materials and solved for the scattering of light using a dipole diffusion …

Multiple scattering in participating media is generally a complex phenomenon. In the limit of
an optically thick medium, ie, when the mean free path of each photon is much smaller than
the medium size, the effects of multiple scattering can be approximated by a diffusion …

We present a new BSSRDF for rendering images of translucent materials. Previous diffusion
BSSRDFs are limited by the accuracy of classical diffusion theory. We introduce a modified
diffusion theory that is more accurate for highly absorbing materials and near the point of …

Shadow maps are a very efficient means to add shadows to arbitrary scenes. In this paper,
we introduce Translucent Shadow Maps, an extension to shadow maps which allows very
efficient rendering of sub-surface scattering. Translucent Shadow Maps contain depth and …

This paper presents a new method for computing global illumination in scenes with
participating media. The method is based on bidirectional Monte Carlo ray tracing and uses
photon maps to increase efficiency and reduce noise. We remove previous restrictions …

Translucent objects are characterized by diffuse light scattering beneath the object's surface.
Light enters and leaves an object at possibly distinct surface locations. This paper presents
the first method to acquire this transport behavior for arbitrary inhomogeneous objects …

We describe a new mathematical framework for solving a wide variety of rendering problems
based on a non-linear integral scattering equation. This framework treats the scattering
functions of complex aggregate objects as first-class rendering primitives; these scattering …
