create(index, material_spec, surface_group)[source]

Determines the material before and after a surface based on its position.

Parameters:

  • index (int) – The index of the surface within the surface group.

  • material_spec (BaseMaterial | MaterialSpec | tuple | str | dict) – The material specification.

  • surface_group (SurfaceGroup) – The surface group containing the surfaces.

Returns:

  • The material before the surface (None for the object surface).

  • The material after the surface.

Return type:

tuple[BaseMaterial | None, BaseMaterial]
