3D TECHNOLOGY

CHAPTER 1: BACKGROUNDS AND TRANSITION OF 3D

3D technology has been with us in different forms for over 150 years. Recent developments in technology make that the 3d can be tasted by consumers that make that increases the application of 3d as a possibility in the near future

People now a days prefer 3d instead of 2d because many reasons. The biggest reason is how they watch the movie, they see that the characters are out of screen so is very different than 2d, another reason we can list is the use of glasses because people that are watching a 3D movie want to use the glasses to know what happen with them. Another reason is that 3d movies are now made in HD, excellent sound and special effects you can’t see in 2D because the 3d movies make you feel that everything is coming out from the screen. But some people can’t use the glasses because they don’t feel good and comfortable with them but a new glasses were created, that let you watch the 3D movie like 2D but you can’t feel and watch the 3D effect because you will watch the movie like a normal 2D movie

Now 3d is taking control of all cinemas. The movies industry nowadays is making their movies with 3d. with this technology the cinema is changing and the people that have forgotten about the cinema is visiting again the theaters because they want to try this new experience.

Because that the industry is making more 3d movies because the ticket us expensive and they earn more money so they make better 3d movies to get consumers involved by their business and visit the cinema more than once a month that will be more than 20 dollar per month

CHAPTER 2: HOW 3D TECHNOLOGY IS MADE AND HOW IT WORKS

 Cameras

There is a lot of fancy footwork that goes into creating 3D. The real heavy lifting, however, is all just a matter of geometry and precision. To get a 3D image, you essentially need two versions of the same scene filmed from the precisely correct angle as if your eyes were seeing the same scene. Filmmakers need to triangulate the distance between the two cameras and make sure they are focused on the same object. They also need to zoom and track, or move, at the same speed, otherwise the images won’t sync up. In modern film rigs, these two cameras are bolted into place preventing any unwanted jostling or disparity.

 Computer Graphics

There is a difference between creating three-dimensional graphics and images that appear to be 3D in the theater. Again, it’s all just a matter of some high-tech geometry. To get a movie like Toy Story 3 into 3D, animators create two versions of each frame, one from the perspective of each eye. Because computer-generated movies don’t need cameras, it’s much easier to get perfectly synced images and to fine-tune any mistakes in post-production. The downside is that this technique requires a lot of time and elbow grease to get perfect.

It’s possible to create a 3D video game using the same technique; however, games add their own complications. Films and shows are largely pre-recorded and all have a fixed perspective — you can’t move the camera’s focus or orientation when you’re watching a film. Video games allow you to change the perspective by moving your on-screen character. This creates a labor-intensive problem since animators need to create objects that can be seen in 3D from a variety of angles depending on where the
