3D-ready TV sets are thosethat can operate in 3D mode (in addition to regular 2D mode), conjunction with a set-top an LCD SHUTTER glasses,

where the TV tells the glasses which eye should see the image

being exhibited at the moment,creating a steroscopic view.

These TV sets usually support HDMi and(if an LED-backlit LCD Television)

a minimum (input and output) refresh rate of 120 Hz;

glasses may be sold separately.

Toshiba's glasses-free 3D laptop


10/22

the best portable 3D experience, however, was Toshiba'sglasses-free 3D laptop. The laptop has a built-in camerain the screen bezel that it uses for face detectionit

locks onto the user's jaw-line so that it can track themovement of the user's face. The software on the laptopcan dynamically adjust the 3D rendering in order toensure that it offers optimal 3D viewing at the angle

from which the user is looking at the screen.

Most 3D graphics today are based onwhats called the polygon system; its asystem that builds things out of little

flat shapes called polygons.As computers increase their power,they will be able to have more of these

little shapes, more shapes means moreroundness and more objects on screen.

This herd of six eyed giraffes are enjoying an early morningstroll in the sunshine. Every rock on the ground is a realgeometry point cloud object, rather than a flat texture map

or a bump map.

Unlimited Detail can use a variety of different lightin

techniques,

in this case, we are using a shadow map.

But all of this is done by a new sort of method

that we call "mass connected processing". Massconnected processing is where we have a way ofprocessing masses of data at the same time andthen applying the small changes to each part atthe end.

Cameron has used the

Computer generated imagery (CGI)specifically used a novel technique called image-based

facial performance capture that required actors to

wear some special headgears already equipped with

camera. As the actors performed, the camera

transmitted facial movements that were put on

the virtual characters. This made the movementsof the body back to a connected array of systems

which acted out their scenes on a

performance capture stage six times bigger than

anything that was ever used earlier in the industry.

This resulted in an amazingly emotional authenticityby the movie characters.The movies footage was built from around 70% CGI

including its female lead.

Stereoscopic 3D Fusion Camera SysteIt was specially used to bridge up the gaps between scenes and

artistically formed an untraceable connectivity between the live action scenes

and the computer generated scenes.In real life, we see images in threedimensions because our left and right eyes see slightly different images that,

when combined by the brain, deliver a picture that has depth.In old-fashioned 3D cinematography the sort

where your glasses had red and green coloured lenses

a pair of closely-aligned images with different tints

gave the impression of depth by fooling the eyes. But modern 3Dfilms have developed new create the illusion of reality.
