Subsurface scattering

Subsurface scattering or SSS, is a method of handling light that is halfway between polygon rendering and volumetric rendering. In essence, it assumes that any given object is slightly translucent. This translucence is used as a depth calculation. Raycast or raytraced light beams striking the surface of a polygon do not immediately bounce off if the object is reflective. Instead, they continue on very slightly inside the polygon, using the degree of translucency as a guide to how far to penetrate.

Once the target depth is reached, the beam reflects as normal, obeying the rules of diffuse reflection or specular reflection, depending on the settings for that object. It then leaves the object back into the scene, from a point fractionally below the surface of that object. This effect lends considerable realism to a scene, as shadows and dark areas alter depending on the material the object is seemingly constructed from.

Prosthetic Control Systems and Grace of Movement
For a great many, the dream of being graceful and smooth of movement - or even not scattering every item on a desk they try to lean over - is something of a fondly held dream. For others, even being able to walk unaided holds a similar place of reverence.

Large Image Display: A MICA Conference in 2009
The image is of a MICA conference, held in mid 2009, in the VR environment Second Life. It clearly shows the problem with such organisations in worlds such as SL. The sparce scattering of avatars represents less than a quarter of MICA's membership at the time. It also represents al lthe avatars the sim environment could support.
