WebApr 16, 2024 · The Phong reflection model includes a specular reflection term that can simulate such highlights on shiny surfaces; it even includes a parameter to specify a shininess of the material. The shininess specifies how small the highlights are: the shinier, the smaller the highlights. WebDec 19, 2011 · 1. I'm currently trying to make specular lighting on an sphere using glsl and using Phong-model. This is how my fragment shader looks like: #version 120 uniform vec4 color; uniform vec3 sunPosition; uniform mat4 normalMatrix; uniform mat4 modelViewMatrix; uniform float shininess; // uniform vec4 lightSpecular; // uniform vec4 …
WebJan 25, 2024 · The Phong equation is the sum of three different components: Ambient, Diffuse and Specular; that try to produce the result of different light behaviors. The result of each of this components and, therefore of this equation, is an RGB value that represents the amount of light L (or intensity) in each RGB channel that is reflected at point P in ... http://zyanidelab.com/uniform-sampling-phong/
