How Does 3d Movies Work
The ingenius technology works by exploiting human spatial vision discussed previously in episode one this involves some special equipment.
How does 3d movies work. To get a movie like toy story 3 into 3d animators create two versions of each frame one from the perspective of each eye. Its called stereoscopy or stereoscopic vision. The glasses have two polarized lenses which each allow different light through usually left handed circular polarization and right handed circular polarization allowing each eye to see a different version of the film. Because computer generated movies dont need cameras its much easier to.
Thats because the red and green movies would use one camera to film the movie then they would double each frame and project them over each other onto the same screen. 3 d images start out as a simple shape called a wireframe. More and more movies are being offered in 3d in theaters so almost all of us have experienced this new cinematic technology. Stereoscopy is what modern 3d technology tries to duplicate.
One lens of the glasses allows only vertically polarized light the other only horizontally. But when you look at a movie like toy story ii or play a game like tombraider you see a window into a three dimensional world. If youve heard of a stereoscope this is exactly the same idea except in a stereoscope you would typically see stationary photos and here you could show a movie. Now before we get into how does 3d movies work we are going to put some light on 3d image.
Firstly the models are created of individual objects using linked points that are made into a number of individual polygon tiles. Basically movies try to mimic the stereoscopic capabilities of human eyes and the hardest part for 3d movie makers is getting a camera to do the same thing so that they have the right images to send to your eyes via the movie screen. The answer is that modern 3d movies accomplish this by using glasses with polarized lenses. But do we all know how 3d movies work in theaters.
Three dimensional movies use polarized light and special glasses to create two films one for each eye. Youre probably reading this on the screen of a computer monitor a display that has two real dimensions height and width. Essentially movies try to mimic the stereoscopic capabilities of human eyes. A 3d process has three phases that is tessellation geometry and rendering.
But these new 3d movies look even more 3d than those red and green ones.
