Phong shininess
WebPhong lighting is a great and very efficient approximation of lighting, but its specular reflections break down in certain conditions, specifically when the shininess property is low resulting in a large (rough) specular area. The … http://zyanidelab.com/uniform-sampling-phong/

WebThe first is called Phong highlighting. Usually, Phong highlights are described using two keywords: phong and phong_size . The float that follows phong determines the brightness … WebPhong's model combines the ambient, diffuse and specular components into one big, hairy equation. We'll first address the Lambertian part of it, and then get to the Phong Model. ... The e exponent is a number that gives the shininess. The higher the shininess, the smaller the spotlight, because the dot product (which is less than one), is ...

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.
