The speed of applying a full screen effect is independent of the complexity of the image. In 3D rendering applications such as video games, common full screen effects include color filters, depth of field, and full screen bloom. A color filter, for example, may desaturate an image or convert it to grayscale.

Example of Carmack's stencil shadowing in Doom 3. Shadow volume is a technique used in 3D computer graphics to add shadows to a rendered scene. It was first proposed by Frank Crow in 1977 [1] as the geometry describing the 3D shape of the region occluded from a light source.
This tone mapping is done relative to what the virtual scene camera sees, combined with several full screen effects, e.g. to simulate dust in the air which is lit by direct sunlight in a dark cavern, or the scattering in the eye. Tone mapping and blooming shaders can be used together to help simulate these effects.
The 2D system (GUI system) of the A8 Engine is not very powerful (see scripting section), but replaceable using the 3D system if needed. Using Lite-C, most things can be customized. Shader model 3.0 support and post-processing using stages may assist shader programmers in chaining together effects to produce any number of custom-made shader ...
Bloom (sometimes referred to as light bloom or glow) is a computer graphics effect used in video games, demos, and high-dynamic-range rendering (HDRR) to reproduce an imaging artifact of real-world cameras. The effect produces fringes (or feathers) of light extending from the borders of bright areas in an image, contributing to the illusion of ...

Other rendering techniques, such as portal rendering, use the stencil buffer in other ways; for example, it can be used to find the area of the screen obscured by a portal and re-render those pixels correctly. The stencil buffer and its modifiers can be accessed in computer graphics by using APIs like OpenGL, Direct3D, Vulkan or Metal.
