Shading is used traditionally in drawing for depicting a range of darkness by applying media more densely or with a darker shade for darker areas, and less densely or with a lighter shade for lighter areas. Light patterns, such as objects having light and shaded areas, help when creating the illusion of depth on paper.
Phong shading is an improvement on Gouraud shading, and was one of the first computer shading models developed after the basic flat shader, greatly enhancing the appearance of curved surfaces in renders. Shaders are most commonly used to produce lit and shadowed areas in the rendering of 3D models.

Leonardo da Vinci's Vitruvian Man (c. 1485) Accademia, Venice. Drawing is a visual art that uses an instrument to mark paper or another two-dimensional surface. The instruments used to make a drawing are pencils, crayons, pens with inks, brushes with paints, or combinations of these, and in more modern times, computer styluses with graphics tablets or gamepads in VR drawing software.
The principle of solid drawing means taking into account forms in three-dimensional space, or giving them volume and weight. [12] The animator needs to be a skilled artist and has to understand the basics of three-dimensional shapes, anatomy, weight, balance, light and shadow, etc. [ 32 ] For the classical animator, this would be achieved with ...
The software is capable of simulating soft-shading using curved gradients within an area so that the animator doesn't have to draw shading into every single frame. There is also a wide variety of other real-time effects that can be applied to layers or groups of layers like radial blurs, color tweaks that all are resolution-independent .
A shading language is a graphics programming language adapted to programming shader effects. Shading languages usually consist of special data types like "vector", " matrix ", "color" and " normal ".
Cel shading or toon shading is a type of non-photorealistic rendering designed to make 3D computer graphics appear to be flat by using less shading color instead of a shade gradient or tints and shades. A cel shader is often used to mimic the style of a comic book or cartoon and/or give the render a characteristic paper-like texture. [1]
