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

Pointing device
Mice are not very apt to draw, so graphics tablets are an essential tool for digital illustrators, as they allow users to easily make marks in all directions, in ways that reflect natural or "live" lines made by human hands. In addition to motion flexibility, industry standard digital image tablets have pressure-sensitive surfaces, allowing the illustrator to make varying marks from fainting to thickness, and from thin to wide. This variation mimics traditional wet and dry media. Drawing on a digital image tablet begins to feel natural after about a week of practice. Hybrid graphics tablets/displays may be helpful, as artists can see more accurately where to place scratches on images, but today's hardware is much more expensive.

Illustration software
There are two main types of tools used for digital illustration: bitmapped (also known as "raster") and vector applications. Bitmap applications are usually called "painting" programs, while vector apps are called "drawing" programs. These terms reflect the differences in look and feel between images created in each type of program. With bitmap applications, content is stored digitally in rows and fixed pixel columns, which can be created in separate layers to more easily isolate and manipulate different parts of the image. The bitmap image contains information about each color of pixels (color), luminance (brightness), and saturation (color intensity). When the pointing device moves above the image area, new colors and values ââare applied to the underlying pixels. The painting tool allows easy creation of "fuzzy" images, including effects such as light and soft shadows, and textures such as feathers, velvet, stone and leather, and is widely used in photo retouches.
With vector-based tools, content is stored digitally as a resolution-independent mathematical formula that describes lines (open paths), shapes (closed paths), and color filling, scratches or gradients. The vector path is constructed from anchor points and road segments by using pointing devices to click and drag. Many vector graphics are available for download from online databases that can then be edited and incorporated into larger projects. The drawing tools usually create the right lines, shapes, and patterns with well-defined and exceptional edges to work with complex constructions such as maps and typography. Digital illustrations can include raster and vector graphics in the same work. Bitmap image files can be stored in formats that embed a vector information layer, and vector image files can include imported bitmap images.
