It is of 3-D
A single image random dot stereogram (SIRDS) is a computer-generated image consisting of seemingly random dots or lines, which, when viewed properly, coalesce into a previously unseen 3-D illusion. To see the hidden illusion, the viewer must relax the eyes and focus on a point in space behind the image. SIRDS work in the same way that stereoscopes, anaglyphs, and Polaroid 3-D movies do. Each eye receives a slightly different image, which the brain integrates into a single 3-D illusion. SIRDS became popular in the early 1990s with the Magic Eye series of books.
In random scan display the electron beam is directed only to the part of the screen where the picture is to be drawn. Random Scan monitor draw one picture at a time therefore they are also known as vector display.refersh rate or random scan system depends on the number of times to be displayed. Picture definition is stored in an area of memory called refresh display file.
raster scan display -based on television technology.where as random scan display based on hard copy devices.raster scan display cannot directly pass electron beam through the scan line..but random scan directed the beam toward the scan line.
Raster-scan:-q1) Raster displays have less resolution.q2) The lines producced are ziz-zag as the plotted values are discrete.q3) High degree realism is achived in picture with the aid of advanced shading and hidden surface technique.q4) Decreasing memory costs have made raster systems popular.Random scan:-q1) Random displays have high resolutions since the picture definition is stored as a set of line drawing commands and not as a set of intensity values.q2) Smooth lines are produced as the electron beam directly follows the line path.q3) Realism is difficult to achieve.q4) Random-scan system's are generally costlier.
Graphics can be important to technical writing, if the graphics accurately represent the current state of the technology. Too often, the technology morphs and changes, so that the graphics become different from the technology -- this is the danger of using graphics in technical writing.
Graphics programming is when you manually draw an item to your application instead of using a picture box, label, or button. To start drawing graphics you need to import the graphics library. Imports System.Drawing.Graphics Then create a new graphics Dim g As New Graphics that is it. when you call "g" you will have many operators in it to draw to the forum. Hope this helps :)
plen plotter is most example of random scan display

Application of Raster scan display: Basically it is used in Plotters. and mainly more like....Printers,,,,
they put random numbers
The process of representing continuous graphics object as a collection of discrete pixel is called Scan Convertion.
it blows up your computer. SORCE i have shrapnal in my eye
Display File is a memory area which stores picture definition as a set of line drawing commands.Video controller interprets these commands and produces actual image on the screen.Display File in random scan system is comparable to frame buffer in raster scan system, on the basis of their functions.
Graphics card, and RAM ( Random Access Memory )
(Graphics Double Data Rate, version 5) SGRAM is a type of high performance dynamic random-access graphics card memory usually used for graphic cards. Its fast!
Displaying or capturing a video image line by line. Computer monitors and TVs use this method whereby electrons are beamed (scanned) onto the phosphor coating on the screen a line at a time from left to right starting at the top-left corner.
