Albedo

Albedo is the fraction of sunlight that is diffusely reflected by a body.

See Phong reflection model and Albedo

Bidirectional reflectance distribution function

The bidirectional reflectance distribution function (BRDF), symbol f_(\omega_,\, \omega_), is a function of four real variables that defines how light from a source is reflected off an opaque surface.

See Phong reflection model and Bidirectional reflectance distribution function

Blinn–Phong reflection model

The Blinn–Phong reflection model, also called the modified Phong reflection model, is a modification developed by Jim Blinn to the Phong reflection model. Phong reflection model and Blinn–Phong reflection model are computer graphics algorithms and shading.

Bui Tuong Phong

Bui Tuong Phong (December 14, 1942July 1975) was a Vietnamese-born computer graphics researcher and pioneer.

Channel (digital image)

Color digital images are made of pixels, and pixels are made of combinations of primary colors represented by a series of code.

See Phong reflection model and Channel (digital image)

Computer graphics

Computer graphics deals with generating images and art with the aid of computers.

See Phong reflection model and Computer graphics

Diffuse reflection

Diffuse reflection is the reflection of light or other waves or particles from a surface such that a ray incident on the surface is scattered at many angles rather than at just one angle as in the case of specular reflection. Phong reflection model and Diffuse reflection are shading.

See Phong reflection model and Diffuse reflection

Dot product

In mathematics, the dot product or scalar productThe term scalar product means literally "product with a scalar as a result".

See Phong reflection model and Dot product

Empirical modelling

Empirical modelling refers to any kind of (computer) modelling based on empirical observations rather than on mathematically describable relationships of the system modelled.

See Phong reflection model and Empirical modelling

Facial recognition system

A facial recognition system is a technology potentially capable of matching a human face from a digital image or a video frame against a database of faces.

See Phong reflection model and Facial recognition system

Gamma correction

Gamma correction or gamma is a nonlinear operation used to encode and decode luminance or tristimulus values in video or still image systems.

See Phong reflection model and Gamma correction

Lambertian reflectance

Lambertian reflectance is the property that defines an ideal "matte" or diffusely reflecting surface. Phong reflection model and Lambertian reflectance are shading.

List of common shading algorithms

This article lists common shading algorithms used in computer graphics. Phong reflection model and list of common shading algorithms are shading.

Normal (geometry)

In geometry, a normal is an object (e.g. a line, ray, or vector) that is perpendicular to a given object.

See Phong reflection model and Normal (geometry)

Phong shading

In 3D computer graphics, Phong shading, Phong interpolation, or normal-vector interpolation shading is an interpolation technique for surface shading invented by computer graphics pioneer Bui Tuong Phong. Phong reflection model and Phong shading are computer graphics algorithms, shading and Vietnamese inventions.

Photograph

A photograph (also known as a photo, image, or picture) is an image created by light falling on a photosensitive surface, usually photographic film or an electronic image sensor, such as a CCD or a CMOS chip.

See Phong reflection model and Photograph

Pioneer anomaly

The Pioneer anomaly, or Pioneer effect, was the observed deviation from predicted accelerations of the Pioneer 10 and Pioneer 11 spacecraft after they passed about on their trajectories out of the Solar System.

See Phong reflection model and Pioneer anomaly

Pioneer program

The Pioneer programs were two series of United States lunar and planetary space probes exploration.

Pixel

In digital imaging, a pixel (abbreviated px), pel, or picture element is the smallest addressable element in a raster image, or the smallest addressable element in a dot matrix display device.

See Phong reflection model and Pixel

Principal component analysis

Principal component analysis (PCA) is a linear dimensionality reduction technique with applications in exploratory data analysis, visualization and data preprocessing.

See Phong reflection model and Principal component analysis

RGB color model

The RGB color model is an additive color model in which the red, green and blue primary colors of light are added together in various ways to reproduce a broad array of colors.

See Phong reflection model and RGB color model

Set (mathematics)

In mathematics, a set is a collection of different things; these things are called elements or members of the set and are typically mathematical objects of any kind: numbers, symbols, points in space, lines, other geometrical shapes, variables, or even other sets.

See Phong reflection model and Set (mathematics)

Shader

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. Phong reflection model and shader are shading.

See Phong reflection model and Shader

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.

See Phong reflection model and Shading

Specular highlight

A specular highlight is the bright spot of light that appears on shiny objects when illuminated (for example, see image on right). Phong reflection model and specular highlight are shading.

See Phong reflection model and Specular highlight

Specular reflection

Specular reflection, or regular reflection, is the mirror-like reflection of waves, such as light, from a surface.

See Phong reflection model and Specular reflection

Surface (mathematics)

In mathematics, a surface is a mathematical model of the common concept of a surface.

See Phong reflection model and Surface (mathematics)

Thermal radiation

Thermal radiation is electromagnetic radiation emitted by the thermal motion of particles in matter.

See Phong reflection model and Thermal radiation

Unit vector

In mathematics, a unit vector in a normed vector space is a vector (often a spatial vector) of length 1.

University of Utah

The University of Utah (the U, U of U, or simply Utah) is a public research university in Salt Lake City, Utah.

3D computer graphics

3D computer graphics, sometimes called CGI, 3-D-CGI or three-dimensional computer graphics, are graphics that use a three-dimensional representation of geometric data (often Cartesian) that is stored in the computer for the purposes of performing calculations and rendering digital images, usually 2D images but sometimes 3D images.
