---|---|---|---|
reflectance |
spectrum or texture |
Specifies the diffuse reflectance of the material. Default: 0.5 |
P ∂ |
transmittance |
spectrum or texture |
Specifies the diffuse transmittance of the material. Default: 0.5 |
P ∂ |
The bi-Lambertian material scatters light diffusely into the entire sphere. The reflectance specifies the amount of light scattered into the incoming hemisphere, while the transmittance specifies the amount of light scattered into the outgoing hemisphere. This material is two-sided.
Note
This material is not designed for realistic rendering, but rather for large-scale simulation of atmospheric radiative transfer over vegetated surfaces.
