Volumetric Shadow

Volumetric shadows or shadow volumes are a technique for creating shadows in virtual environments by using a polygonal volume as the shadow, created using real-time shadow geometry in each frame more often than not, for the most accurate and thus realistic shadowing. This polygonal area then greatly simplifies the prospect of casting sub-shadows, since if a second model is partially in the shadow volume, that part must therefore be in shadow.

The Looming Shadow of DVT
DVT or Deep Vein Thrombosis is a condition which is already known to affect airline travellers, and office workers. Thrombosis occurs when people are sitting still for long periods of time. Blood clots form in the arteries where blood is settling over long periods of time - as opposed to circulating properly when moving briskly around. This tends to be more of a problem in the lower legs when sitting, but can occur in any part of the body when fully reclined.
