- 4. A 3D or3-D (three-dimensional) film or S3D (stereoscopic 3D) film is a motion picture that enhances the illusion of depth perception. Derived from stereoscopic photography, a regular motion picture camera system is used to record the images as seen from two perspectives (or computer- generated imagery generates the two perspectives in post-production), and special projection hardware and/or eyewear are used to provide the illusion of depth when viewing the film. 3D films are not limited to feature film theatrical releases; television broadcasts and direct-to-video films have also incorporated similar methods, especially since 3D television and Blue- ray 3D.
- 5. Hold up yourfigure about an arm length in front of your face stair and close your right eye then the left eye what do you notice? Brain use a process call stereoscopic to translate these two images to depth perception
- 6. Stereoscopy (also calledstereoscopies or 3D imaging) is a technique for creating or enhancing the illusion of depth in an image by means of stereopsis for binocular vision
- 7. More modern choicefor cheap 3d Allow color viewing . Two synchronized projector project two respective view onto the screen, each with a different polarization. The glasses allow only one of the image into each eye because they contain lenses with different polarization. The brain does the hard work again , combining two separate image into a single 3D one. Used in most of today 3D theaters…
- 8. Used at HOMETHEATER. Image Looks Great. There is a battery in it. The TV rapidly flash alternating left-eye and right –eye video frames at 120 times per second. Through the glasses you will see a one picture for each one at time , But the left/right video image. Alternate so quickly that you perceive a full, three alternate so quickly that you perceive a full, three-dimensional view…
- 9. PASSIVE 3D V/SACTIVE 3D PASSIVE 3D ACTIVE 3D ITS CHEAP.. PASSIVE 3D DOSE NOT REQURED CHARGING.. THESE GLASSES ARE LIGHT & EASY TO USE.. NO HARMFULL EFECTS… ITS COSTY.. ACTIVE 3D NEEDS TO BE CHARGE BEFORE USE.. THEY R HEAVY IN COMPARISION OF ACTIVE 3D. PEOPLE COMPLAIN ABOUT HEADACHE .

TOSHIBA:: ”Due to the possibility of impact on vision development , viewers of 3D video images should be above 6 years‘….” Watching TV for long time is not good .. Some risk 6 or 8 while using NINTENDO 3DS “potential impact on growth of children eyes” PC MAC, FOX. Can effects older people in different ways.. Very little research is done on EFFECTS OF 3D VIEWING ON CHILDREN ADULTS
- 16. PEVENTIONS FOR USING 3D Takethe glasses off if u feel stress and relax for around 30 sec Never wear 3D glasses outside .. Get your eyes check periodically if you use 3D TV daily ..
