自從電腦CG普及之後，越來越多的人喜歡用電腦做一些插畫設計。

CG在我們身邊，無處不在！CG的含義是泛指所有的電腦圖形和數碼影像，只要是使用電腦或者是使用數碼技術生成的圖形和影像我們都可以把它稱為CG。我們的電影、廣告、數碼攝影、電腦遊戲、圖書繪製排版、建築圖設計還有網站方面的設計都是數碼藝術的範疇！現在有很多朋友開始接觸和從事CG 這方面的工作，我覺得這是件非常好的事情。

The term computer graphics includes almost everything on computers that is not text or sound. Today almost every computer can do some graphics, and people have even come to expect to control their computer through icons and pictures rather than just by typing.

Here in our lab at the Program of Computer Graphics, we think of computer graphics as drawing pictures on computers, also called rendering. The pictures can be photographs, drawings, movies, or simulations -- pictures of things which do not yet exist and maybe could never exist. Or they may be pictures from places we cannot see directly, such as medical images from inside your body.

We spend much of our time improving the way computer pictures can simulate real world scenes. We want images on computers to not just look more realistic, but also to BE more realistic in their colors, the way objects and rooms are lighted, and the way different materials appear. We call this work "realistic image synthesis", and the following series of pictures will show some of our techniques in stages from very simple pictures through very realistic ones.

Computer illustration or digital illustration is the use of digital tools to produce images under the direct manipulation of the artist, usually through a pointing device such as a tablet or a mouse. It is distinguished from computer-generated art, which is produced by a computer using mathematical models created by the artist. It is also distinct from digital manipulation of photographs, in that it is an original construction "from scratch". (Photographic elements may be incorporated into such works, but they are not the primary basis or source for them.)

There are two main types of tools used for digital illustration: bitmapped and vector. With bitmapped tools, the content is stored digitally in fixed rows, columns, and layers, containing information about each pixel's hue, luminence, and sometimes filter settings. Popular examples include Photoshop, Paint Shop Pro, Corel Painter, and the GIMP. With vector-based tools, the content is stored digitally as resolution-independent mathematical formulae describing lines, shapes, and color gradients. Popular examples include Freehand, Illustrator, CorelDRAW, and Inkscape.
