Phong reflection
WebThe Phong model states that the light reflected in the direction of the viewer varies based on the angle between difference between the view direction and the direction of perfect reflection. Mathematically, the Phong model looks … Phong shading may also refer to the specific combination of Phong interpolation and the Phong reflection model, which is an empirical model of local illumination. It describes the way a surface reflects light as a combination of the diffuse reflection of rough surfaces with the specular reflection of shiny surfaces. It is based on Bui Tuong Phong's informal observation that shiny surf…

WebOne of those models is called the Phong lighting model. The major building blocks of the Phong lighting model consist of 3 components: ambient, diffuse and specular lighting. Below you can see what these lighting components look like on their own and combined: ... We calculate a reflection vector by reflecting the light direction around the ...
Phong reflection is an empirical model of local illumination. It describes the way a surface reflects light as a combination of the diffuse reflection of rough surfaces with the specular reflection of shiny surfaces. It is based on Phong's informal observation that shiny surfaces have small intense specular highlights, while … See more The Phong reflection model (also called Phong illumination or Phong lighting) is an empirical model of the local illumination of points on a surface designed by the computer graphics researcher Bui Tuong Phong. … See more The Phong reflection model is often used together with Phong shading to shade surfaces in 3D computer graphics software.
