ABSTRACT
Translucent photon mapping is a technique developed for the realistic rendering of translucent materials such as milk, skin, and fog. In the physical world, however, no material is perfectly translucent at a constant density. By using a 3D density map for a rendered object and jittering the values of the map by using a Perlin noise function will create a non-perfect density throughout the object and thereby present a more realistic image.

Special Issue: The Very Best Papers from CASA 2004Obscurances is a powerful technique that approximates indirect global illumination in a much faster way than classic methods as radiosity or path tracing. In this method, the local environment of a point or a patch is sampled to estimate the amount of ...
Real-Time Realistic Skin Translucency
Diffusion theory allows the production of realistic skin renderings. The dipole and multipole models allow for solving challenging diffusion-theory equations efficiently. By using texture-space diffusion, a Gaussian-based approximation, and programmable ...
