Hidden Surface Determination
Hidden surface determination, also known as hidden surface removal, visible surface determination or occlusion culling, is simply a method of determining in a 3D environment filled with objects of various types, transparencies and distances, which surfaces and parts of surfaces are not visible from a certain viewpoint or viewpoints. Once this determination is made, they can be removed from the scene without affecting the final result for that frame, but increasing redraw speed as unnecessary data is not processed.

At the start of May 2008, Engineers at Eyebeam, an engineering and design firm based in New York, created a scaled-down open-source version of Microsoft Surface, called Cubit.
Here we see the lovable disaster area that is Robo Dog 3000. As we find out much later in the film, Robo is a cyborg, much like the other members of Stepford. AA champion terrier's brain plus a minimal life support system, is hidden inside that shell, and hooked to considerable neuroprosthetics. This allows the dog to behave and think like a normal dog, whilst appearing to be fully robotic.

A creature from worldwide mythology, included for content within the virtual. The Ahl al-trab come from Islamic folklore. Living in burrow-homes just, literally just, below the surface of the Saharan sands, These humanoid creatures are tiny; practically flightless pixies.
Much of the work in launching a new world, is spent on creating the fundamental technologies that lay under the surface: Databases, daemons, graphical APIs, you name it. All of these have been written before, and continue to be written, improved and perfected now. Why write your own, when great ones are available, pre-made, and ready for you to build from?
Powering a neuroprosthetic is a tricky issue. As most of these devices are implanted either on the surface of the brain, or deep inside its folds, it is not a trivial matter to pop it out and change the battery. But, what if the same sugar that feeds the brain, could also feed the prosthetic?
One of the key issues when printing electronic circuits on the fly, is ensuring reliability. You don't wish to be in the situation where you have to go over the new circuitry by hand to look for places the conductive ink has not affixed to the surface properly, not if you are making complex 3D shapes with internal circuitry, and aiming to keep the price as low as possible.
The making of a bespoke prosthetic jaw from a patient's existing medical data is one of those things that seems both easy and obvious on the surface, but one which is frought with implementation issues when you get right down to it. Could it really be as simple as laying down on a CT bed, and letting the computer do the rest?
