Computer Graphics is a term to describe the drawing of objects on a display. The original task was to change tiny little squares from on to off and back. The display would be just black and white (no grey scale) and these tiny boxes, known as pixels, would turn on for white and off for black. This allowed for text, pong and the beginning of the personal computer evolution. Soon after, inventors discovered they could shade the pixels to be brighter or darker, ultimately creating grey scale.
Today, computer graphics have jumped leaps in order to build great games or movies. Games have provided many advances in light shading and real world physics. Calculations are made to determine what boxes get changed to what colors. In a video game, the user can make decisions that can effect the the angle or lighting of a particular object. So the computer has to make split-second decisions on what colors the pixels need to be. These pixels are put together in an attempt to make things appear real world.
Computer graphics will continue to make great advances to make visual representations more and more realistic. We have come a long way from black and white boxes and a screen to the high quality and fast visual representations. It will be exciting to see what comes next.
Hello Andrew,
ReplyDeleteYou did a good job introducing the idea of computer graphics with the description about pixels and how they are put together in video games. I liked the pictures you used on this post including the Mario picture where it shows how Mario’s character design has changed over the years. There were a few grammar errors, but a quick reread should be able to fix them. Keep up the good work.
Great job on describing the progression of graphics! I enjoy the visuals, and having grown up with Mario, can appreciate the progression from many perspectives. I found your writing clear and personable, and well within the context of the article. Good Job.
