Diffuse refraction of light
 |
Diffuse refraction scatters light in many angles. |
Specular refraction
 |
Specular surfaces reflect light at the same as the angle at which the light strikes the surface. |
Glossy refraction
 |
Glossy surfaces are actually specular surfaces with micro surfaces at angles to surface plane. These micro surfaces refract light not only specularly but also diffusely (at angles very close to the specular transmission), giving the surface a glossy appearance. |
