| summary |
Bui-Tuong Phong published his illumination model in 1973, in the paper titled "Illumination for Computer-Generated Images". Phong's model is a local illumination model, which means only direct reflections are taken into account. Light that bounces off more than one surface before reaching the eye is not accounted for. While this may not be very realistic, it allows the lighting to be computed efficiently. To properly handle indirect lighting, a global illumination method such as radiosity is required, which is much more expensive. In addition to Phong's basic lighting equation, we will look at a variation invented by Jim Blinn. Blinn changed the way specular is calculated, making the computations slightly cheaper. Blinn published his approach in his paper "Models of Light Reflection for Computer Synthesised Pictures" in 1977. |
