Blinn-phong reflection model
WebIn ray tracing, the reflection calculation is performed when a visual ray hits a reflecting surface. In this case, the direction of reflection r is calculated using the viewing direction v (direction of the visual ray) and the normal n at the point of intersection. The calculation according to the Blinn-Phong model is: WebJul 6, 2024 · The Phong reflection model in particular describes the light reflected from surfaces or emitted by light sources as the combination of 3 components: diffuse, ambient and specular. The model also requires information about the direction in which a particular surface is facing, provided via vectors called surface normals.
