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. WebThe Phong model says that the specular component is proportional to the cosine between the light reflection vector and the eye vector. The following image shows this graphically: L is the vector from the light to the vertex being shaded. N is the normal vector, and Eye is the vector from the vertex to the eye, or camera. can a deputy jailer arrest someone

http://science-and-fiction.org/rendering/glsl_4.html WebIn the fragment shader we create a struct to store the material properties of the surface. We can also store them as individual uniform values, but storing them as a struct keeps it more organized. We first define the layout of the struct and then simply declare a uniform variable with the newly created struct as its type.
