Image data, unless modified by pixel zoom, generally has a one-to-one correspondence between a pixel in an image to a pixel on the screen. In fact, this is where we get the term pixel (picture element). In this chapter, we extend this knowledge further by applying images to three-dimensional primitives. ...
