1. Diffuse reflection:
- small grained, rough surface
- the incoming light is reflected in all directions
2. Mirror (specular) reflection:
- glossy, refined surface
- the incoming light is reflected at the same angle (angle of incidence equals the angle of reflection)
3. Retroreflection:
- there are two kinds of retroreflection: spherical and cube corner
- the incoming light is reflected back in the direction that it came from (to return light back to its source)
