Subsurface scattering is an indirect form of reflection where some of the light is transmitted into a semi-transparent material, scattered under the surface and bounced back out again.
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]
Shaders are written in OpenGL Shading Language and compiled. The compiled programs are executed on the GPU. The compiled programs are executed on the GPU. OpenGL Shading Language ( GLSL ) is a high-level shading language with a syntax based on the C programming language .
This shader works by replacing all light areas of the image with white, and all dark areas with a brightly colored texture. In computer graphics, a shader is a computer program that calculates the appropriate levels of light, darkness, and color during the rendering of a 3D scene—a process known as shading.
In the field of 3D computer graphics, deferred shading is a screen-space shading technique that is performed on a second rendering pass, after the vertex and pixel shaders are rendered. [2] It was first suggested by Michael Deering in 1988. [3] On the first pass of a deferred shader, only data that is required for shading computation is gathered.
Open Shading Language (OSL) is a shading language developed by Sony Pictures Imageworks, a Canadian visual effects and computer animation studio headquartered in Vancouver, British Columbia and Montreal, Quebec, with an additional office on the Sony Pictures Studios lot in Culver City, California, a unit of Sony Pictures Entertainment's Motion Picture Group, which through an intermediate ...
An example of bloom in a computer-generated image (from Elephants Dream).The light on the bright background bleeds on the darker areas, such as the walls and the characters.
A pair of carbon brushes. A brush or carbon brush is an electrical contact, often made from specially prepared carbon, which conducts current between stationary and rotating parts (the latter most commonly being a rotating shaft) of an electrical machine. [1] Typical applications include electric motors, alternators and electric generators. The ...
