WebApr 16, 2024 · Per-pixel lighting is also known as Phong shading (in contrast to per-vertex lighting, which is also known as Gouraud shading). This should not be confused with the Phong reflection model (also called Phong lighting), which computes the surface lighting by an ambient, a diffuse, and a specular term as discussed in Section “Specular Highlights”. WebScience and Fiction - GLSL shader coding - Blinn-Phong Shading Blinn-Phong Shading One of the goals of rendering is to put a credible appearance of light into the scene - we want to show how illumination changes as objects move through the scene. The most widely-used scheme to do that is the Blinn-Phongmodel.

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.
