WebNov 5, 2024 · Blinn Phong is the default lighting model for different editors and environments, with its specular reflection. Some Comparison Images: Lambert, Blinn and Phong, Source: CGRU 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. Apart from this, it may also be used for other purposes. For … See more • List of common shading algorithms • Blinn–Phong shading model – alteration of the Phong reflection model to trade precision with computing efficiency See more The Phong reflection model was developed by Bui Tuong Phong at the University of Utah, who published it in his 1975 Ph.D. dissertation.

WebAug 21, 2016 · The reflective component is determined by further ray tracing. The other component is calculated via the equation from the Phong reflection model. Our ray tracer currently adds both components as in (1 - reflectivity) * color + reflectivity * trace (reflected_ray, depth + 1) where color is determined by the Phong equation.
