Rendering in visual art and technical drawing means the process of formulating, adding color, shading, and texturing of an image. It can also be used to describe the quality of execution of that process. When used as a means of expression, it is synonymous with illustrating. However, it may be used for mere visualization of existing data regardless of any preconceived message or idea to express. Rendering is also a technique that can be used while designing packaging and branding.
Artistic rendering is the application of visual art styles to rendering. For photorealistic rendering styles, the emphasis is on accurate reproduction of light-and-shadow and the surface properties of the depicted objects, composition, or other more generic qualities. When the emphasis is on unique interpretive rendering styles, visual information is interpreted by the artist and displayed accordingly using the chosen art medium and level of abstraction in abstract art. In computer graphics, interpretive rendering styles are known as non-photorealistic rendering styles, but may be used to simplify technical illustrations. Rendering styles that combine photorealism with non-photorealism are known as hyperrealistic rendering styles.
