Example of lambertian transmitter material

Description

This material type diffuses light in transmission. No light is reflected back from the incident ray, it is fully transmitted, and scattered evenly in every direction. This is similar to the lambertian material, except that it is transmitting instead of reflecting.

This material used on its own is unrealistic and very unlikely to be found in nature. However, a blend of this material type with another diffuse material, such as lambertian, oren-nayar or phong will help modelling thin translucent materials, such as sheets of paper, leaves, cloth, and many other, which diffusely transmit a fraction of incident light.
