i just need the definition!!!!!!
Answer
Stereopsis (from stereo meaning solidity, and opsis meaning vision or sight) is the process in visual perception leading to perception of stereoscopic depth. In turn, stereoscopic depth is the sensation of depth that emerges from the fusion of the two slightly different projections of the world on the two retinas. The difference between the two eyes' images, which is a result of the eyes' horizontal separation, is usually referred to as binocular disparity or retinal disparity. The fact that this binocular disparity is interpreted by the brain as depth was first discovered by Charles Wheatstone, a British scientist, and described by him in a classic paper[1] published in 1838: â⦠the mind perceives an object of three-dimensions by means of the two dissimilar pictures projected by it on the two retinæâ¦â, (Wheatstone, 1838). To prove his ideas, Wheatstone invented a simple device which he dubbed a stereoscope. Using his newly invented stereoscope Wheatstone was able to convincingly show that a vivid sense of depth emerges from two completely flat pictures depicting two different projections of the same scene.

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.[1] 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.
Traditional stereoscopic photography consists of creating a 3-D illusion starting from a pair of 2-D images. The easiest way to create depth perception in the brain is to provide the eyes of the viewer with two different images, representing two perspectives of the same object, with a minor deviation similar to the perspectives that both eyes naturally receive in binocular vision. If eyestrain and distortion are to be avoided, each of the two 2-D images preferably should be presented to each eye of the viewer so that any object at infinite distance seen by the viewer should be perceived by that eye while it is oriented straight ahead, the viewer's eyes being neither crossed nor diverging. When the picture contains no object at infinite distance, such as a horizon or a cloud, the pictures should be spaced correspondingly closer together.

My computer keeps freezing?
sirhouse
My computer freezes a lot to the point where its become "useless". I'll list the history of what happened to it and if anyone has a fix to it I'm literally going to explode out of happiness.
I got my first blue screen playing a 3D game called minecraft, all I had to do was restart my computer and it worked again. This kept happening but not to the point where it was annoying, it rarely happened.
But I kept playing games and it got to the point where I would get a blue screen after a few minutes every time I played any game or video.
I asked a question on here a while ago and I got some help that told me it was the graphics card/driver. I uninstalled the graphics driver and reinstalled it, but the problems continued.
I thought it had to be an overheating problem so I removed the back case of my laptop. But in fact this made it much worse and I thought it was because now my RAM sticks weren't seated securely and they were moving around causing it to crash much more commonly. So I took one out I couldn't find the other one but this didn't change anything at all except now it crashes even when I'm not doing anything video related like surfing the web.
Anyways thats where I'm at now. I think its a problem with the hardware because it kept getting worse over time, but I don't know what parts not working. Thanks for ANY advice/pointers!
Answer
What Operating System your using?
Suggest running the Memory Diagnostics Tool from Microsoft:
http://windows.microsoft.com/en-nz/windows7/diagnosing-memory-problems-on-your-computer
If one or more memory sticks is corrupted at a point, then your find that your computer will randomly crash (when it has reached and tries to use that address). So, this could happen at any time - boot time, during any application/game, etc. If this is your issue, then carefully remove all memory sticks (after removing static from your body by grounding yourself - for example: touching a piece of metal area on the computer) except for one and retest each individually... place back any good ones and replace the damaged one(s).
Next scan your computer hard drive(s) for errors, go under "My Computer" -> Right click on each Local Disk (one at a time) -> Properties -> Tools (tab) -> Erroring Checking -> Check Now. Select automatically fix file system errors and also check for bad sectors option. If the drive is in use, it might ask to check on next boot up instead (say okay and restart).
Next scan your computer for viruses, spyware and trojans. If you already have an virus scanner, then ensure it is up-to-date as well as Windows, a good firewall and other applications you use regularly. Most virus scanner are utter rubbish, I recommend total application control rather than virus definition only scanners. This means something which gives or denies each application/game access to various areas of your system (including itself) with a strong firewall to prevent any network access, such as Kaspersky Internet Security.
You can check with some free tools, such as: http://www.kaspersky.com/virus-scanner
Also, check for spyware using a free manual running application (which doesn't conflict with your virus scanner) such as Lava Soft Ad-Aware: http://www.lavasoft.com/products/ad_aware_free.php or Spybot: http://www.safer-networking.org/dl/
Next clean out any startup background applications and/or services you don't need. This is more advance, only remove what you know is and don't want. You can use Start -> Run -> type "MsConfig.exe" and press enter, then look under the Startup tab, also more carefully under the Services tab (Leave it alone or Google search the name of each if unsure what it is/does).
