"Specular" color with phong shading and raytracing …
https://stackoverflow.com/questions/55544793/specular-color-with-phong-shading-and-raytracing-overflows
To figure out the reason was not complicated: It is calculated this way: specular_color += light_intensity * std::pow (reflected*camera_dir,mat.ns); where mat.ns is the specular exponent, that exhibits the expected values. reflected*camera_dir is the cause, because it always end being a big value. In three of four of my test cases it is a five ...

Phong shading | Computer Graphics | Fandom
https://graphics.fandom.com/wiki/Phong_shading
Template:Mergefrom The term Phong shading is used indiscriminately to describe both an illumination model and an interpolation method in 3D computer graphics. Phong reflection is a local illumination model devised by Bui Tuong Phong and can produce a certain degree of realism in three-dimensional objects by combining three elements - diffuse, specular and ambient …

Blinn-Phong shading - LaValle

The Blinn-Phong shading model proposes that some amount of light is reflected, depending on the amount of surface shininess and the difference between and [ 24 ]. See Figure 7.3. The bisector is the vector obtained by averaging and : ( 7. 3) Using the compressed vector notation, the Blinn-Phong shading model sets the RGB pixel values as. maxmax.
