Line 91: ==Reflection and shading models== ~~Modrn~~Modern 3D computer graphics rely heavily on a simplified reflection model called ''[[Phong reflection model]]'' (not to be confused with [[Phong shading]]). In refraction of light, an important concept is the [[refractive index]]. In most 3D programming implementations, the term for this value is "index of refraction," usually abbreviated "IOR."
