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.

![]() A brief but thorough multi-part article from Gamasutra, on creating volumetric rendering in real-time, for use in fog, fluid, and other effects, which correctly affect light at any point through them. The Perspecta display system was released by Actuality Systems in May 2005. Its intended purpose is as a 3D volumetric display capable of projecting a virtual object right in front of you. ![]() ![]() ![]() ![]() ![]() A coder?s article about creating realistic, dynamic soft shadow in real-time interactive, and complex scenes. ![]() ![]() ![]() ![]() Read this series for the twisting, evolving, many diverse threaded storyline, or read them for the wonderful imagery, and enchanting ideas for VR of the future. Whichever reason makes you pick up one of these, you are in for one hell of a ride! ![]() ![]() ![]() 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.
