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.

Specular color determines the color of the highlight ( GL_SPECULAR ). In addition, users need to determine how shiny a surface is ( GL_SHININESS ). Figure 2 shows specular color changes from the same color to white from bottom to the top. WebMar 6, 2024 · Description Vectors for calculating Phong and Blinn–Phong shading In Phong shading, one must continually recalculate the dot product R ⋅ V between a viewer ( V) and the beam from a light-source ( L) reflected ( R) on a surface. If, instead, one calculates a halfway vector between the viewer and light-source vectors, H = L + V ‖ L + V ‖ tatum login

WebFeb 11, 2015 · a shininess of 0 seems like a reasonable value to specify for a Phong material that shouldn't be shiny That's not how the Phong reflectance model works. Decreasing the shininess value only increases the size of the specular highlight and does not change the brightness of the highlight.
