The vertex position can be transformed to view space as discussed in the tutorial on diffuse reflection. For the implementation of the specular reflection, we require the direction to the viewer in view space, which we can compute as the difference between the camera position and the vertex position both in view space.

The shader code for the ambient lighting could be straightforward with a component-wise vector-vector product. The specular term of the Phong reflection model is then. Similarly to the case of the diffuse reflectionwe should clamp negative cosines to 0.ДЇor example, all highlights in Caravaggio's painting are white. The specular reflection term computes the specular reflection in the direction of the viewer V. Thus, we have to negate our direction L to use this function. In GLSL, the function vec3 reflect vec3 I, vec3 N or vec4 reflect vec4 I, vec4 N computes the same reflected vector but for the direction I from the light source to the point on the surface. Mathematically, the normalized reflected direction R is defined by. For less than perfectly shiny surfaces, light is reflected to directions around R : the smaller the shininess, the wider the spreading. A perfectly shiny surface will reflect light from the light source only in the geometrically reflected direction R. The shininess specifies how small the highlights are: the shinier, the smaller the highlights. If you have a closer look at Caravaggio's painting, you will see several specular highlights: on the nose, on the hair, on the lips, on the lute, on the violin, on the bow, on the fruits, etc. In Blender, the ambient light is specified in the World tab of a Properties window. Apparently there is always some light being reflected from walls and other objects to illuminate everything in the scene - at least to a certain degree.ДЄnalogously to the equation for diffuse reflection in the tutorial on diffuse reflectionthis equation can also be interpreted as a vector equation for the red, green, and blue components of light. While large parts of the white shirt are in shadows, no part of it is completely black. If you haven't read the tutorial on diffuse reflectionthis would be a very good opportunity to read it.Д¬onsider the painting by Caravaggio to the left. Together, the three terms constitute the Phong reflection model. It extends the shader code in the tutorial on diffuse reflection by two additional terms: ambient lighting and specular reflection. Posted 26 April - AM To make discussion about a maybe future version easier I think it's a good idea to start talking about it here.This tutorial covers per-vertex lighting also known as Gouraud shading using the Phong reflection model.
