Stereopsis is an optical illusion where our brain sent our eyes the signal to visualize a two-dimensional object as a three-dimensional object. This optical illusion has been used as a trick in the 3D film Avatar. The film has used high tech active glasses with side by side liquid crystal display (LCD’s) in place of lenses. The two LCD’s opened and closed alternatively and synchronized with the images on the screen via radio transmitters in the theatre thereby inducing the brain of the viewer to form a three-dimensional illusion. Except for few sequences, there was no camera used in the studio where Avatar was made. The actor’s movement was recorded by motion capture which suited their body movements and facial expressions. James Cameron integrated the digital image of the characters with a 3D image of the virtual environment of Pandora generated in real time so that he could see the 3D world as he directed the movements of the actors and could remake a scene if he did not like it (Straubhaaar,2013). Visual effects can be described as animation done in support of “live action plates” and it is primarily about surroundings and noncharacter dynamics. Avatar takes this idea further. The technology of visual effects makes us believe that fantasy places like that of Na’vi’s Pandora as depicted in Avatar exists in reality. Avatar is basically a photorealistic animated film with live-action plates created in the support of animation. Computer generated imagery has become a common element in film production. CGI has replaced other form of camera, optical and special effects. CGI has enhanced photorealism in Avatar through the creation of a realistic background in the film. It has created fantastic imagery in the film. CGI creates background images using the three-part process: developing the spatial characteristics of the object through the 3-D model, producing the finished image and then animating the object and stimulating movement (Valk & Arnold, 2013). Avatar is 90% computer generated and has live-action features. The design of creatures and characters play a very important role in any film having visual effects.
