Computer Graphics: Create it

computer graphicsA lot of us have doodled or made something before. At a very young age, especially, children let their imagination go wild and do many interesting things. They talk, draw, and build anything that is in their mind. It is amazing because it can be very creative sometimes. Drawing is easy to do, but it is hard to make it look very realistic and appealing to the eye. Now, we can draw on computers; computer graphics is a category. Drawing on computers is harder than drawing manually, but it is worth it because your hard work looks very realistic.

Computer graphics are "graphics created using computers and the representation of image data by a computer specifically with help from specialized graphic hardware and software." It is basically things on the computer that is not text or sound. You use the computer to create and manipulate an image data, making it visually appealing to the audience. Computer graphics are used in many different fields: animation, movies, and video games. In the website Computer Graphics World, you can see different articles and news about computer graphics; it is like an online magazine.

image processing
Related to computer graphics, there is also image processing. It is "any form of signal processing for which the input is an image, such as a photograph or video frame; the output of image processing may be either an image or a set of characteristics or parameters related to the image." The image is treated as "a two-dimensional signal, applying standard signal-processing techniques to it." In other words, it is a way to convert an image into digital form so you can perform, or edit, operations to make it visually appealing or extract information from the image. There are two types of image processing: analog and digital. Analog, or visual techniques, can be used for hard copies such as photographs and printouts. Digital is for manipulation of digital images by using computers.

Computer graphics is a great field for people who like to draw and create animation. It is a big step from manual drawing to computer drawing. For animation, instead of drawing the same picture over and over again on flip paper and flipping it to create a visual story, you can do it with ease on the computer.

  1. I think digital design is a very lucrative field especially in the digital age. If you mess up creating an image all you have to do it undo that step. with paiting and taking photos you have a seemingly huge project that can get very messy while adobe photoshop allows you to organize and group together parts of your projects. the bad part of the using a computer to make digital images is that you could lose all your work instantly, and it has a large cost. A good computer and adobe suite can cost up to 6,000 dollars. I do agree that it can be very creative, just costly.

  2. Nice post. I especially like your introduction. It is very interesting and true. In addition, I also agree with you that with computer drawing, creating animation becomes easier and much faster. In the past, it took a huge amount of time to create animation because it was very inefficient to draw the same picture over and over. While using computer drawing, it allows you to make changes on the same picture. Computer graphics is a great field for people who are interested in drawing and creating animation.

  3. Hi Ryan,
    What an informative post you have! Your post helps me visualize the Computer Graphic in hardware term and in software term. I also interested in image processing. I use Photoshop to alternate images for years, and I’m still wondering how that can be done. However, I’m not so sure about the differences in applications of processing Analog images and Digital Images you mentioned in your post. it would be great if you could give an example for each type. I do understand what is a digital image, but I don’t quite sure about what is analog image. Overall, this is a good post, and I very enjoying reading it.
