  2. Gradation (art) - Wikipedia

    en.wikipedia.org/wiki/Gradation_(art)

    Artists use a variety of methods to create gradation, depending upon the art medium, and the precise desired effect. Blending, shading, hatching and crosshatching are common methods. A fading effect can be created with pastels by using a torchon. [2]

  3. Shading - Wikipedia

    en.wikipedia.org/wiki/Shading

    Shading refers to the depiction of depth perception in 3D models (within the field of 3D computer graphics) or illustrations (in visual art) by varying the level of darkness. [1] Shading tries to approximate local behavior of light on the object's surface and is not to be confused with techniques of adding shadows, such as shadow mapping or ...

  5. Hatching - Wikipedia

    en.wikipedia.org/wiki/Hatching

    In Western art, hatching originated in the Middle Ages, and developed further into cross-hatching, especially in the old master prints of the fifteenth century. Master ES and Martin Schongauer in engraving and Erhard Reuwich and Michael Wolgemut in woodcut were pioneers of both techniques, and Albrecht Dürer in particular perfected the ...

  6. Skiagraphia - Wikipedia

    en.wikipedia.org/wiki/Skiagraphia

    Skiagraphia is often described as a hatching technique used to create the illusion of forms through shading. [1] The shading is created by the use of curved lines, either by the use of hatching or cross-hatching. Within this same approach, painters can use different colors to add shade to an area.

  7. 3D rendering - Wikipedia

    en.wikipedia.org/wiki/3D_rendering

    A simple example of shading is texture mapping, which uses an image to specify the diffuse color at each point on a surface, giving it more apparent detail. Some shading techniques include: Bump mapping: Invented by Jim Blinn, a normal-perturbation technique used to simulate wrinkled surfaces. [10]

  9. Computer graphics lighting - Wikipedia

    en.wikipedia.org/wiki/Computer_graphics_lighting

    The lighting and shading at that vertex is then calculated using the average normal and the lighting model of choice. [32] This process is repeated for all the vertices in the 3D model. [2] Next, the shading of the edges between the vertices is calculated by interpolating between the vertex values. [2]
