Specular highlights are what make objects look shiny. Unlike diffuse illumination, where light scatters equally when it hits a surface, specular illumination goes in a particular direction. When it goes directly into the eye, it makes a highlight.

At this point, I can get the reflected color using a reflection ray (possibly recursively), an environment map, and also calculate a specular highlight for the light source (s) I have. I sum whatever reflection colors I have, multiplied by the amount of reflection from the fresnel equation.

Hello, I've been working on a Ray Tracer, in OpenGL using C++. I'm fairly new to both of these things so I'm struggling with certain elements of the shading, I feel like the mathematics used are correct in my code and I'm simply not combining the Ambient, specular and Diffuse properly. ...

Raytracing - how to combine diffuse and specular color?

Update 2: One actual solution would be to calculate the phong contribution to the final pixel color (that is your variable mySpec).The idea is to only use a part of the diffuse component where the specular is actually not 0, that is, if you have some specular component, you don't actually see the diffuse component that much (or at all) so it can be adjusted for:

Images stored with floating point numbers, allowing a wide range of values, are often calledhigh dynamic range(HDR) images to distinguish them from fixed- range, orlow dynamic range(LDR) images that are stored with integers. See u = l u = r v = b v = t j i –.5 3.5 j = 2.5 j = –.5 u = 0 u = 1 v= 0

A specular highlight is the bright spot of light that appears on shiny objects when illuminated (for example, see image at right). Specular highlights are important in 3D computer graphics, as they provide a strong visual cue for the shape of an object and its location with respect to light sources in the scene.
