Computer Graphics are created when the user of a computer creat visual images by visual computing. This can be done by changing or combining spacial information from a sample, usual taken from the authentic world. There are two kinds of computer graphics. These are two-dimensional (2D) and three-dimensional (3D) graphics. 2D graphics consists only on a plane generally using X and Y coordinates. Vector and raster graphics are used when creating 2D graphics. Vector graphics use points to create lines while raster graphics uses a two-dimensional grid or pixels to create standard shapes. 3D graphics are created by using X, Y, and Z coordinates. Polygons are created and then rendered by using shading, texturing, and rasterization. Graphics may also be rendered based on image.
