Demo effect

Demo effects are computer-based real-time visual effects found in demos created by the demoscene.

Displacement mapping

Displacement mapping is an alternative computer graphics technique in contrast to bump mapping, normal mapping, and parallax mapping, using a (procedural-) texture- or height map to cause an effect where the actual geometric position of points over the textured surface are displaced, often along the local surface normal, according to the value the texture function evaluates to at each point on the surface.

Distance transform

A distance transform, also known as distance map or distance field, is a derived representation of a digital image.

Finite difference

A finite difference is a mathematical expression of the form.

Greeble

A greeble or nurnie is a fine detailing added to the surface of a larger object that makes it appear more complex, and therefore more visually interesting.

Heightmap

In computer graphics, a heightmap or heightfield is a raster image used to store values, such as surface elevation data, for display in 3D computer graphics.

Java applet

A Java applet was a small application that is written in the Java programming language, or another programming language that compiles to Java bytecode, and delivered to users in the form of Java bytecode.

Jim Blinn

James F. Blinn (born 1949) is an American computer scientist who first became widely known for his work as a computer graphics expert at NASA's Jet Propulsion Laboratory (JPL), particularly his work on the pre-encounter animations for the Voyager project, his work on the Carl Sagan documentary series Cosmos, and the research of the Blinn–Phong shading model.

Lookup table

In computer science, a lookup table is an array that replaces runtime computation with a simpler array indexing operation.

Normal (geometry)

In geometry, a normal is an object such as a line or vector that is perpendicular to a given object.

Normal mapping

In 3D computer graphics, normal mapping, or Dot3 bump mapping, is a technique used for faking the lighting of bumps and dents – an implementation of bump mapping.

Parallax mapping

Parallax mapping (also called offset mapping or virtual displacement mapping) is an enhancement of the bump mapping or normal mapping techniques applied to textures in 3D rendering applications such as video games.

A parallel of a curve is the.

Phong reflection model

The Phong reflection model (also called Phong illumination or Phong lighting) is an empirical model of the local illumination of points on a surface.

Pixel

In digital imaging, a pixel, pel, dots, or picture element is a physical point in a raster image, or the smallest addressable element in an all points addressable display device; so it is the smallest controllable element of a picture represented on the screen.

Programmer

A programmer, developer, dev, coder, or software engineer is a person who creates computer software.

Real-time computer graphics

Real-time computer graphics or real-time rendering is the sub-field of computer graphics focused on producing and analyzing images in real time.

Rendering (computer graphics)

Rendering or image synthesis is the automatic process of generating a photorealistic or non-photorealistic image from a 2D or 3D model (or models in what collectively could be called a scene file) by means of computer programs.
