Linked Constant Light Output

Linked constant light output is a paradigm that comes into play when the virtual reality system's display part consists of multiple projectors, overlaying their output to create a combined panorama. One of the most complex issues with any multiple-projector display is maintaining a steady lumen count. Lumen is a measure of brightness, and if one projector is brighter than another it will show up markedly inside the simulation.

If one projector is displaying a predominately dark image, and another a predominately bright image – shadow contrasted to full sun for example – then even if the projectors are calibrated to the same lumen standard, one will be emitting more light than the other, and the two images will differ in brightness even where they are showing something that is supposed to be of equal brightness such as the same area of reflective surface.

Linked Constant Light Output counteracts this by linking the projectors together with an internal simulation. The control program calculates before displaying each frame, how the relative light levels produced by the projectors will look inside the simulator, and makes adjustments to the overall brightness of each projector to compensate.

Using Linked Lists to Represent Game Objects
An introduction to the uses of linked lists, for creating, manipulating, and destroying large numbers of objects at any one time. A very good technique to know for large worlds, or complex situations.

Podcast: Tim Berners-Lee: The next Web of open, linked data
This podcast comes from TED 2009, by the original inventor of the Internet. He looks at the next stage in the Internet's evolution; open, linked data.



At CES 2009, Nvidea unveiled a system of active glasses. Specifically, shutter glasses. The frames alternate polarisation to block light out every second frame, so that each eye gets half the screen update rate of any normal monitor, but will work with a normal output stream just fine.

Large Image Display: Animatrix: Beyond: A Broken, Glowing Light
n a broken part of the ruin of an area of heavy file corruption, a light flickers. Upon closer inspection, it's a broken light bulb, hanging from a rusty chain. Yet every so often, the ghost of an intact bulb, shinning brightly, overlays the broken one perfectly.

The Real Virtual Light
Virtual Light, a term coined to describe seeing without eyes, is something that has been semi-mythical for decades, whilst research quietly moves forwards. Now, we are starting to see a convergence of the technologies vital to making it a reality.



Announced just one day after the Nintendo Wii itself, at E3 2006?s second day, the Nintendi Wii light-gun attachment connects directly to the back of the Nintendo Wii-mote immersion controller.





Virtual Light is classic Cyberpunk in every sense: it is dark, and gritty, a surreal near-future world that sets you on edge, and both the main characters have sunk as low as it is possible to go, before attempting to change the world for the better.





An expressive face is a work of art. Constantly moving and changing. Lips, brows, frown lines, each is in constant motion. Stop Staring analyses facial structures and movements, then shows animators how to bring life to the faces of their characters.
