What is 2D computer graphics?

Two -dimensional or 2D, computer graphics appear flat on the screen and is displayed only from one angle. Old arcade games, such as Pac-Man, offer an accurate representation of 2D graphics. Pac-Man's character and ghosts who chase him seem to see as flat shapes only from one side, regardless of where he moves on the screen. On the other hand, a newer computer or video game contains characters that seem three -dimensional or 3D, and can turn around in circles so that the viewer can see them from all angles. 3D graphics creates the illusion of depth, despite the fact that they are technically still flat images on the screen, while 2D computer graphics do not create this illusion of depth and simply show a flat shape or outline.

to create 2D computer graphics, the artist combines shapes, colors and lines into an image designed for an image with a computer image. The picture can be seen directly from one angle. It could be from behind, next to, front, or even from above characters, but POSTava still seems flat. The angle at which the character is drawn and shading around him can create a gentle illusion of being 3D, but it is still the only flat image.

Unlike 2D image, the 3D image is built around the wire model. It is a network model of lines that create geometric shapes such as balls around which texture and color are applied. This creates a 3D character that can move and be seen from multiple angles. Generating a 3D image requires more computer power than 2D image.

Usually 2D computer graphics are made from a standard image, while 3D computer graphics are made of vector image. Vector images of scale and size to adapt to their container, in this case the computer screen. 2D computer graphics are drawn as illustrations in the book and remain the same size. Newer technology allows 2D images BYly vectors and scaling up and down, but it is basically the same as drawing a flat image and then drawing it to more sizes. On the other hand, the 3D image must also scalance the shading and highlighting on the object to match the new size.

With computers and technologies, they constantly push the boundaries of what they can produce, most images are 3D today and uses smaller 2D computer graphics if necessary. Armor of a character can use 2D computer graphics as a logo painted on it, while a symptom can have a 2D computer graphics. Creating 3D objects compared to 2D objects relies heavily on mathematics to calculate how each piece should connect and move into their environment. The symbol on the building may not change, while the running person must show realistic movements of arms and feet, as well as movement in the hair that follows.
