Last updated 1 year ago

-

Create an opaque radiance modifier from red, green, and blue reflectances.

Inputs

  • name

Text to set the name for the modifier and to be incorporated into a unique modifier identifier.

  • r_ref [Required]

A number between 0 and 1 for the absolute diffuse red reflectance.

  • g_ref [Required]

A number between 0 and 1 for the absolute diffuse green reflectance.

  • b_ref [Required]

A number between 0 and 1 for the absolute diffuse blue reflectance.

  • spec

A number between 0 and 1 for the absolute specular reflectance of the modifier. Note that the sum of this value and the diffuse should be less than one. Specular reflectances greater than 0.1 are rare for 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).

Outputs

  • modifier

An opaque modifier that can be assigned to a Honeybee geometry or Modifier Sets.
