Public Attributes
double	roughness {-1}
	Scale from 0 = specular to 1 = diffuse.

Detailed Description

Global surface normal with smearing.

Roughness range is \( [0, 1] \), where 0 is specular and 1 is diffuse. This parameter is the complement of the polish as defined in Geant4:

roughness = 1 - GetPolish(); 

.

See celeritas::optical::SmearRoughnessSampler .

Note

This model is used by the GLISUR subroutine in Geant3 and the corresponding "glisur" surface model in Geant4.
