Create a translucent radiance modifier from reflectances and transmittances.
The sum of the reflectances and transmittances must be less than 1 and any energy not transmitted or reflected is assumed to be absorbed.
name
Text to set the name for the modifier and to be incorporated into a unique modifier identifier.
r_diff_ref [Required]
A number between 0 and 1 for the red diffuse reflectance.
g_diff_ref [Required]
A number between 0 and 1 for the green diffuse reflectance.
b_diff_ref [Required]
A number between 0 and 1 for the blue diffuse reflectance.
diff_trans [Required]
A number between 0 and 1 for the transmitted diffuse component. This is the fraction of transmitted light that is diffusely scattered.
spec_trans
A number between 0 and 1 for the transmitted specular component. This is the fraction of transmitted light that is not diffusely scattered but passes through like a beam. (Default: 0).
spec
A number between 0 and 1 for the fraction of specularity. Specularity fractions greater than 0.1 are not common in non-metallic materials. (Default: 0).
rough
Roughness is specified as the rms slope of surface facets. A value of 0 corresponds to a perfectly smooth surface, and a value of 1 would be a very rough surface. Roughness values greater than 0.2 are not very realistic. (Default: 0).
modifier
A translucent modifier that can be assigned to a Honeybee geometry or Modifier Sets.
