End of 2008, long vacation, we’re about to go to the movies watching the gorgeous white dog named Bolt from Disney and Pixar in 3D-3D movie. 3D-3D animation movie? And what the hell might it be? “The kind of movie with the latest 3D technology with special glasses to see the movie with depth and almost look alive,” a friend of mind tried to explain.

Ahh, i’ve got the idea. So we have to wear a special kind of glasses while we’re watching the movie. And, tadaa, that cute white dog seem to be very close so we can touch it. The environment now have a depth like a real world. The action does look alive.

Stereoscopy, stereoscopic imaging or 3-D (three-dimensional) imaging is any technique capable of recording three-dimensional visual information or creating the illusion of depth in an image. The illusion of depth in a photograph, movie, or other two-dimensional image is created by presenting a slightly different image to each eye. Many 3D displays use this method to convey images. It was first invented by Sir Charles Wheatstone in 1840.

Stereoscopy is used in photogrammetry and also for entertainment through the production of stereograms. Stereoscopy is useful in viewing images rendered from large multi-dimensional data sets such as are produced by experimental data. Modern industrial three dimensional photography may use 3D scanners to detect and record 3 dimensional information.  The three-dimensional depth information can be reconstructed from two images using a computer by corresponding the pixels in the left and right images. Solving the Correspondence problem in the field of Computer Vision aims to create meaningful depth information from two images.*(Vee)
