What is computer graphics and Its use?

Computer graphics means drawing pictures on a display screen. What’s so good about that? Sketch something on paper—a man or a house—and what you have got could be a piece of analog information: the thing you draw may be a likeness or analogy of something within the planet. Looking at the materials you utilize, changing what you draw may be easy or hard: That is the wonder of art, of course—it captures a fresh dash of creativity—and that’s exactly what we love about it. As every sketching child knows too well if you draw the primary part of your picture too big, you’ll struggle to squeeze everything else on the page, and what if you modify your mind about where to place something otherwise you want to swap red for orange or green for blue? Ever had one among those days where you snap sheet after sheet of spoiled paper and toss it in the trash?

What are computer graphics used for?
That’s why many artists, designers, and designers have fallen taken with special effects. Draw an image on a monitor and what you have got maybe a piece of digital information. It probably looks just like what you’d have drawn on paper—the ghostly concept was hovering in your head, to start with—but inside the computer, your picture is stored as a series of numbers. Change the numbers and you’ll change the image, within the blink of a watch or perhaps quicker. It is simple to shift your picture around the screen, scale it up or down, rotate it, swap the colors, and transform it altogether styles of other ways. Once it’s finished, you’ll put it aside, incorporate it into a text document, print it out, upload it to an online page, or email it to a client or work colleague—all because it’s digital information.

Obvious uses of tricks include computer art, CGI films, architectural drawings, and graphic design—but there are many non-obvious uses still and not all of them are “artistic.” Scientific visualization could be a way of manufacturing graphic output from computer models so it’s easier for people to grasp. Computerized models of worldwide warming produce vast tables of numbers as their output, which only a Ph.D. in climate science could figure out; but if you produce a speeded-up animated visualization—with the planet getting bluer because it gets colder and redder because it gets hotter—anyone can understand what is going on on. Medical imaging is another model of how graphics make computer data more meaningful. When doctors show you a brain or body scan, you are looking at a computer graphic representation drawn using vast amounts of information produced from thousands or maybe even numerous measurements. The jaw-dropping photos beamed back from space by amazing devices just like the Hubble Space Telescope are usually enhanced with the assistance of a sort of lighting trick called image processing; which may sound complex, but it isn’t so very different from employing a graphics package like PhotoShop to the touch up your holiday snaps).
